Cheap 𝙁𝙖𝙠𝙚𝙨 or Impressive New Brakes? Lewis LH4 Full Review

[@DaleStone]

If anybody tells you that these are the best brakes that have ever been made, they are absolutely full of it. What are your favourite brakes? 👇

[@LaurentiusTriarius]

So I'm full of shit? Well yeah not the best ever, I'm impressed by the features and ease of bleeding and quality for the price I got my second set of LH4 a couple days ago from S4 suspension at 499$ CDN so I didn't pay shipping for customs and duties this time, like when nobody wanted these 😅 Anyway my favorite ever are the code RSC but minus the DOT hassle, maybe the Cura but I'd have to retry them it's been awhile.

I pains me to see the Hayes A4s in purgatory at the bottom of the list waiting on scores. Not that I have experience (aside from the A4s) with brakes outside of Sram and Shimano offerings, but the A4s have been completely maintenance free, super reliable and fantastic performers for me. While I don't have daily access to terrain that can properly find their limits, I'm extremely grateful to have them on my bike every time I head out on a weekend trip to the mountains where they can be put to proper use.

I promise to release them from their purgatory in 2024. I can also assure you they'll be scored very well. 🫡

[@owenjohnson9174]

i’ve been riding them for the better part of a year, and i’ll admit they have their ups and their downs, god i hate the lever body clamp, but more importantly they were my primary brake for my dh bike, where a full top to bottom laps at my local park is 1800ft usually 16-20 minutes of pure chaos, and they consistently do fantastic. like dale mentioned it is a lot of rider preference and i love them and would recommend them…just run the glafer pads, more consistent bite point and either the hayes 203 rotors or the sram H2S for the A4😉

[@kaijuoncrack6198]

I love my hayes as well. I weigh 260lb , and these just never fade.

[@SpencerBaum]

I have had the same experience with my Hayes. While my dhr evos leaked all over my pads both times I've bleed them, my Hayes have worked flawlessly and are always super easy to bleed ant maintain. The lever feel of the Hayes is also far and away the best I've ever felt on any brake

[@MtbOverload]

[@saskskier]

My shop had a set of LH4's and hooked me up so we could get a good review in. For science. I live in Calgary and mostly ride in Alberta, interior BC (Golden, Revelstoke, Panorama, etc), but also managed to get some Kamloops and Squamish in as well over the summer. I'm 6'4 and riding weight is around 270lbs, so put any brakes I use to the test. I haven't had any issues with them at all. They've been consistent, have lots of modulation and more than enough power to manage speed and stop me (even on trails like Dead Dog). My bite point and reach adjusters spin freely and I haven't needed pliers to mess around with them. Lever feel is great. I have a great shop who's willing to support if there are any issues, which is awesome. The real question will be long term reliability and access to parts if something needs replacing. So far, zero regrets getting them.

Glad you've had a positive experience. Shop perks!

Nothing that surprise me. I knew they would turn out to be decent brakes, so a good bang for your buck. At this point I'd still wait and see what 2nd iteration will be like, because if they manage to smooth out the few flaws and just carry over what is good with the 1st iteration, it's worth the wait in my mind.

I agree, and hopefully will be testing a set soon.

这是我看过最为详细的关于lewis刹车与它的制造商的相关视频，感谢您做出的努力！在中国，一些厂商将仿制作为进入某个行业的方式。他们在仿制产品后会做一些非常小的改进，便将其称为自己的设计，这个现象在自行车行业尤其明显。例如，tideace就仿制了santa cruz hightower与norco range并在淘宝上销售。这种现象在中国也被反感。很高兴看到lewis并没有止步于仿制产品并出售，而是继续进行改进，这是一个好的趋势。在中国，影响lewis刹车销售的一个原因是价格。禧玛诺刹车在中国的非官方售价非常有竞争力，例如m8120仅需190美元左右，m9120仅需约300美元（显然，没有任何售后与质保），而lh4刹车的售价约为235美元。影响lewis刹车销售的另一个原因是其不同批次的质量并不稳定，据我所知有一些lewis刹车存在漏油问题。所以，许多人会选择更为便宜且成熟可靠的禧玛诺产品。我希望lewis可以更好的改进他的刹车系统，我也希望可以在您的频道继续看到关于lewis刹车的内容😉😉nice work dale！

I love this series! I'm sure you've already heard, but just a heads up that there is a grub screw on the reach adjust knob that is used to lock your reach in place. That probably just needs to be loosened in order to fix your need for pliers. Also, I throw my little adjustment Allen knob thing under my fork top screw cap. I keep it in the little plastic bag it came with and it doesn't rattle around at all!

Indeed, I will be testing it our shortly. I appreciate you reaching out here and on IG. 🙂 Now that's a good hack for the adjustment knob!

Great detailed review. Not something I'm about to run out and buy given I'm running Shimano MT-400 with 6100 levers and am happy with them but always fun to bike geek on something that looks super cool and controversial.

[@spacedoutboy404]

Another great review! Informative and entertaining as always. As someone who owns both Direttissima and Piccola HD brakes, I would like to point out that at some point Trickstuff changed the C42 caliper to take the same pads as SRAM Codes/ Guides. The current sets no use the Hope E4/ Shimano pads.

[@diran971]

I have the LV4 (bought them at their Taobao shop. Bought 2 pairs, the first one at the end of 2023 but the bike where they were installed got stolen in January... Bought the other pair in May and been using them since. Had no issues with the reach adjustment dial on both of the pairs but did have issues with the clamp on the first pair. On the second pair, they give me the new clamp but seems like you have the old one. Their new clamp is very similar to Trickstuff's new clamp (what a coincidence). Another thing, i have the silver model and one of the calipers came slightly shinier than the other parts for some reason... It's not an issue at all but I noticed that. Other than that, they have been really good so far. Best brakes i ever had and hope they'll last long :)

[@GrigoryRechistov]

Out of curiosity, I watched Lewis's bleeding video last week and I can confirm that it is quite detailed and thorough. It reminded me one Park Tools video on the bleeding of Shimano brakes in which Calvin went way over the regular procedures that us mere mortals do under bleeding.

[@a8f235]

Park Tool still show gravity bleed and pushing dirty fluid up through the lever side, instead of sucking it out through where most dirt comes from, which is the caliper. In my mind you should start by sucking out the dirty fluid first through the caliper, and then fill up with fresh fluid and start the actual bleed process when all the fluid is fresh. Gravity bleed is a joke and very outdated. I feel Park Tool try to stay in line with what certain brands recommend, instead of following what seems more reasonable. You can bleed Shimano brekas the SRAM way just by choosing to do so, and I wish Shimano would update themself on this area as well as making threads inside the bleedport for a more secure bleed.

[@GrigoryRechistov]

@@a8f235 Given how many brands and vendors showcase this method simply means that there is likely no measurable difference in which direction to push the fluid. Yeah, in theory there could be dirt there and getting rid of it kinda makes sense as a hypothesis. But is there really any reliably *measurable* difference? And speaking of dirt, does it make a difference where it gets pushed first if in the end its gets purged? Let's not forget that the bleeding process is primarily meant to evacuate air bubbles. If someone has serious dirt and water in their brake lines, maybe it is too late to reason about in which direction the filth should be pushed. They likely have more serious problems on their hands, which require a caliper rebuild with consequent bleeding to fill in the system again.

[@GrigoryRechistov]

@@a8f235 And by the way, I always thought that *gravity* bleed means that the old fluid is evacuated from the bottom, being driven there by gravity. I.e., that's the traditional Shimano method. And forcing the old fluid to leave from the top at the caliper by using a syringe at the bottom works against gravity. But maybe my interpretation is wrong.

[@a8f235]

@@GrigoryRechistov By relying on gravity you have no control over what you hopefully want to achieve(removal of air bubbles) so how do you know there are no airbubbles left... With a syringe you have direct control over what you want to achieve, which drastically increase your chances of removing as much as possible. You should want to probe the system instead of scratching your head hoping for a miracle. How do you even troubleshoot a gravitybleed? In regards to your way of thinking that amount of brands(people) doing something equals more right is completely wrong, because truth doesn't care who or how many believe in it. Truth is its own entity, so I couldn't care less how many people follow something if I personally believe it is wrong. There is a good reason why there are so many videos about brake bleeds and what ever else, simply because the industry cannot make up its mind about something that should be easy for people who have been working within the industry for so long. Park Tool produce a lot of good tools(and I do own a lot of it myself) but in certain areas they can feel a bit outdated. Obviously they have got a lot of proper knowledge, so I have no intention of throwing them completely under the bus as I've mentioned I do own lots of their tools and intend to keep using them for good reason. I'm just tired of seeing brake bleed videos surfacing every spring, like how many ways of doing this is there, really... The industry need to make up its mind. PS: About contaminated brake fluid, it's as simple as why compromise the lever side of things if you don't have to, because it is a choice to push the fluid out the top or you push it out the bottom. It's the same as when I store my bike I always engage the lowest gear so the gearcable will be slack. Why have constant tension on it if you don't have to(My bike will be stored for at least 7 months at a time because of winter). It's just certain things at least I feel is good practice, because then you know you have cared about something which you can put into something else as well.

[@GrigoryRechistov]

​@@a8f235 Many good points I agree with. Totally agree that if many people do something, that does not mean that it is a right thing to do. > how do you know there are no airbubbles left... Exactly, and in fact Park Tools' video for Shimano brakes has them forcing the oil in both directions at separate steps, and then rotating the lever into two ±45° positions to hunt for even more bubbles. A crazy involved process. Still, I have a feeling that the pushing order does not matter that much. Like, is it even proven that all dirt that comes in is heavier than oil? If there is some dirt that is lighter than oil, it will float up anyway, and in this case pushing it down would be the wrong thing. And yes, my brakes, when I bleed them, often vomit out nasty brown shit :-)

[@cmcmillan22]

Just an FYI I’ve got a set of the new LV4 brakes and I wanted to comment on them, beside them feeling amazing the fit on the lever adjustment Nob is perfect, tight enough they don’t move but loose enough I can adjust easily even with gloves on.

[@DaleStone]

Thanks, always gotta cite your sources! 🤓

[@BrawndoDrinker]

Interesting! Thanks as always for the deep dive. I need to go find your XTR review to find why the reliability of the 9120 was so low. I've had multiple sets of the older XTR 2 pistons that I move from bike to bike for over a decade and only had one lever seal fail. Was considering a set of Trinity's but the order process is a joke, and I found a set of 9120s for half your MSRP, so I am running them now and will compare to my old sets. I really prefer the levers of Shimano, but hate the no rebuild/repair policy they have on so much of their stuff. Cura's are pretty good too if you ever get around to them.

[@DaleStone]

I have the script done for the XTR video... But haven't gotten around to filming it yet. The tl;dr is that I've managed to make just about every bit of those brakes fail over time.

[@psyguy37]

Been waiting for this review, thanks for your take! Only a couple weeks left in the season for me before a long winter, so I have many months to make my final decision. I'm hoping the next gen Lewis brake becomes available from S4 during that time as now that's the model that interests me most. It also looks like new Saint will actually release by the spring as well which is another strong contender. New Saint will likely be double the price of Lewis though, so they'll need to be something special.

[@DaleStone]

It looks like their LHP model will be coming to north america sooner than you think, given that it's been on sale in China for a bit already.

[@viperrules24]

Good review I am (almost) considering replacing my SLX brakes to try these out! :) One thing to note: I don't know if its a good idea to NOT back off the deadstroke adjust screw completely during a bleed. I believe not doing so will prevent some fluid movement and if there is air trapped in that chamber, it might not be released during the bleed process. I believe both SRAM and Shimano suggest winding the screw all the way out during the bleed for this reason. Perhaps what you did in your video is the best way to get a minimal deadstroke: plan for a shakedown ride after a bleed to prevent the issue #1 that you had.

[@DaleStone]

It was quite effective at eliminating dead stroke, that much is for sure haha! 🚫⚰️

18:17 I thought that was intended for extra grip on the lever. That's what I've seen on Instagram. I've messaged Lewis about holes in the lever for grip, I was told they did not do it, to not weaken the lever, but they told me they will do it, but not sure if they will make indents or holes. but later months later I saw people posting pictures with the tape shown here on the lever. 19:22 Good idea to implement this. I forgot when I asked them about it but I asked them when ever I saw their brakes first, but this confirms they were actually worked on this. But it seems like they worked on it before i asked them about it. But I think it's strange they did not implement it. But if they weren't lying in the reply I got they might do it, they wrote they will. 18:24 brake clamp moving, is unacceptable.

[@kevinxodemonth]

Cracked open the master cylinders on a pair of LH4 to replace the seals on the pistons because the bite point had gotten inconsistent. Downsides: the internals (and parts) didn't QUITE match the schematics/exploded diagram that Lewis sent us (rolling improvements, maybe), and disassembly required a 1.3mm hex! Had to go out and buy a bit kit specifically for this task. Upsides: the manufacturing quality is absolutely up there with the best; the user (brakes weren't mine) said that the braking performance was excellent... when they were working properly, that is; Lewis aftersales support and service was responsive and helpful. I hope they do well and continue to give the big brake boys some food for thought. EDIT: we tried the seal replacement method because that was what Lewis recommended. On opening up the master cylinder, the seals and piston design didn’t match what their exploded drawing was showing, so I made the call to just bleed and reassemble instead of replacing it with the new seals they had sent. No complaints from the user so far, but the bike is coming in again later this week so I will report back!

I used carbon paste to stop my Lewis brakes from slipping on my carbon handle bars. It made a huge difference.

The torque required to keep the matchmakers from moving is way too much.

[@sprousaTM]

Really love the design on the nebula. Would match quite nicely my Dreadnought v1 deep space nine frame. This thing is though, that these brakes cost around 400-420€ here in Germany. That's basically the same price as a set of Hope Tech4 E4s and only around 50€ less than a pair of V4s. Considering that the V4s come with 3 pairs of brake pads for each side (race, ebike and standard), which all work pretty fine (standard ones are a bit lackluster though), it's at least in Germany a bit hard to really recommend them to anyone. The E4s come with 2 pairs of pads which basically makes them as pricey as the Nebula Lewis ones. I am a big fan of Hope Tech4s (riding 2 sets of V4s on e-enduro and the bio enduro and a set of E4s on my trailbike), which just work perfectly and have a huge following on the bike market for years and a lot to come. I'd really love to give the Lewis ones a try (heck I even installed some alieexpress ipro4 ones on my hardtail, which work great for 80€ a set :D ), but they need to come down with the prices a lot.

I even rebuild the hopes after two years of use with a hope service kit (accidentally damaged a piston seal during a very bad bleed). Since then they are like new again and it was very easy to do. I like that hope doesn’t change their design every other week and you’ll get the service kits for years to come.

[@TheMTBRider96]

As always, very nice and complete video, can't wait to see the maximas to have a direct comparison with the Trinity, and next year with the Hopes V4 ( hopefully v4 ). from my almost non existent experience with lewis if not a lever squeeze, the lht are really light so i was expecting the lh4 to be the same, but i was wrong apparently

[@DaleStone]

The power curve is solid, but the dead stroke lever force is disappointingly average.

[@mtbboy1993]

16:29 Usually this is a symptom of pistons needed lubing, once cycled trough properly it should fix it, unless seals are worn, in this case that's impossible as they are new. I'm not sure how an adjustment would make the pistons get stuck. Maybe the seals are bad. But what you said makes sense. Fluid expanding making the brakes lock up. This shouldn't happen. I wonder if they used thread locker on the adjustment dials.

[@ChazFMTBChronicles]

[@illestFlavor]

Am also curious what you think of the M820 Saints.

[@Vwise]

Sounds like the freestroke adjuster can be adjusted too far in effectively making it a closed system with no access to the reservoir. This would lead to the situation you had where heat expanded fluid can't expand into the resivoir so instead it prevents the caliper pistons from being able to retract. Assuming this is what's happening bleeding the system with the bleed screw all the way in wouldn't solve this. You wouldn't be able to bleed the system with the freestroke screw this far in as the resevoir would be closed off from the master piston. That's my guess as to what's happening based purley on theory and never seeing these brakes in person.

[@DaleStone]

Plausible theory, could be an oversight!

[@bullit4x]

So. I might try them. Spice it up some. You gave them the same overall as my beloved Slx and actually better than my Xt’s. And I am a bit sweet on the silver and camouflage flavored ones.

[@DaleStone]

If you want to minimize fatigue and make sure you'll be able to easily service them anywhere in the world, keep your XTs. If you want flashy colours with a fantastic build quality, but a question mark in terms of serviceability and warranty support, try these! ...and double check that 160 doesn't void your warranty.

Hey Dale I wanted to ask have you considered doing a lever swap with the sram mavens? Kind of like shigura, but I guess we can call it Leven? As it seemed most of your complaints were with the levers not the calipers. I've seen someone on instagram swap on lewis LHP levers funnily enough and they said it was a huge improvement in the lever feel, with easily 50% less force needed. This as a shigura user has me interested because you can get a maven caliper new for 80 usd, same price as the mt5 caliper but more powerful

[@leafydialupking1]

Damn man, sneak peaking the Hayes dominations in the chart. Hope the heck can you rate them 9 for service they have like the least pleasant bleeding experience of any brakes I’ve had. I can see marking down the maguras because you need a special bleed cup to thread into the master but that’s the only real annoying part of them. Once you have the special cup, you just attach a catch cup to the caliper and moto bleed them just like shimano and hope. The dominions have that dual syringe fuckery and the juggling of the caliper bleed screw while praying you don’t let too much air in while you’re at it. And you can’t take the pads out the top, so you have to remove the wheel or caliper to pull the pads.

[@DaleStone]

The bleed seemed fairly ordinary to me, and I always take the wheel out wherever doing anything brake related anyways, so neither of those are big cons to me. Where Hayes scored well was the excellent (but not perfect) ability for customers to purchase service spares and very clear rebuild documentation. I'll probably reduce it to an 8, but right to repair is a huge deal for me and Hayes is one of the best in that regard.

After this review i believe these breaks got alot of negativity for 3 reasons : 1. Visual resemblance to Trickstuff (and people seem to love picking on things) 2. China (also affecting point 1) - people have a silly by me opinion on chinese made products while generally using alot of well build, in China appliances inntheir daily life without complaining 3. Being a relativelly new brand They sure sound good for the price at least, while the early adopter may seem like a risk, it feels there is potential for a serious competitor here if the company persist and improves on posible issues reported on these aparently early generation sets

[@DaleStone]

You are correct, and it is worth noting that on 99% of the internet, the negativity is not performance based and largely caused by people who do not own these brakes. 🙂

Silly marketing. I want all parts to be easily available to buy. But I think it was a British distributor that claimed they have all spare parts.

They seem like good brakes.. interesting they're a "controversial" chinese brand. I'd assumed they were a UK brand because the name sounds British. But also the first time i heard of them was Louise Anna Ferguson, who races for Intense Factory Racing on the UCI DH World Cup, doing a bike check & mentioning how, just like many of the racers now running SRAM Mavens, she had to drop back to 203 rotors from 220 because the brakes were so powerful. This was a bike check at the Crankworx Whistler, Canadian Open on the Stevie Smith 1199 course which is STEEP.. Yes that's right, Intense Factory Racing uses Lewis Brakes. Not sure which model but if the Intense factory team uses them they must be pretty decent.. In my experience with brakes, Magura MT5, SRAM Code Rs, & Shimano XT. The best brake system is Shigura, when you combine the Magura caliper with an XT, XTR, or Saint lever. Combining the 2 systems brings out the best in both of them. The modulation & power of Magura with the snappiness of Shimano, without the carbotecture lever of Magura or the on/off of Shimano. I'd imagine its like Trickstuff or Maven performance for a third the price. And cheaper to get Shimano levers to replace a broken Magura one as theyre prone to do in crashes, as i experienced when my lever body broke after a crash. Mind you it was my 4th crash on the same levers, but the shimano lever bodies wopuld just not break like that. But the Magura calipers are far better than the Shimano calipers with better heat resistance & in my experience the pads last longer.

[@HollyBoni]

@@danharvey3096 I've been running a Shigura setup for 2-3 years on one of my bikes, I have to disagree about the modulation bit. IMO the power delivery of a Shigura setup is something like "everything all at once at the beginning of the stroke". Then sometimes you pull harder when you need more power, and it's just not there. It works fine for me, I only notice the lack of modulation when I'm following slower people. Maybe I'm just imagining things, maybe I suck at modulating brakes. But when people who run full Magura setups try my bike, they always comment on how grabby my brakes are. I also had multiple Shimano levers develop a leak at the master cylinder, and since it's Shimano you can forget about serviceability and spare parts, but that's another story. IMO a Shigura setup is great when your bike came with those lame MT5 levers, and they feel über powerful in parking lot tests, but they're far from the best brakes out there. And I haven't even mentioned the constant pad drag that's part of the Magura life. 🙃

[@trevors2041]

Hey Dale, I'm in the process of installing my LH4s right now! Mine came with the two bolt clamp design, but the threads are VERY rough... Definitely going to run a tap through them as even with the lever off the newly added bolt is stiff (and I think I saw some shavings/flakes fall out of it?) and it's hard to determine how much force you are actually applying to the carbon bars. The new two-bolt clamp doesn't feel up to the same machining quality as the rest of the setup. Coming from Code RSCs with a Problem Solver MMX adapter for the M8100 shifter, I was in for a surprise when my shifter now doesn't mount to my bike and its the Friday of Thanksgiving long weekend ☹guess I didn't do enough homework on the Lewis Matchmaker adapter, and just assumed I would be able to make it work.

I told my bro that the pads and rotor is just as more important than the brake set itself. Lever gives everyone that placebo effect because of the tension its feeding back to the rider. Once people figure out that they should use their knuckle and not the tip of their fingers to pull the lever, they will notice less force to pull the levers and less hand fatigue.
