How to Bleed Hydraulic Brakes - Shimano® Flat Bar Levers

Just took my bike into a REI and they got it done for just a little more than what the kit was worth. Yeah, I will never bleed my own brakes again.

This is why i still stick to mechanical cuz its easier

[@kartboarder22g17]

I work on cars and this just seems like too much, imagine tilt the car at a 30 degree angle. Remove the caliper to bleed it. lol

[@lazerblade75]

Simple and easy to follow. Takes the mystery and expense out of bike maintenance. I can do it I can learn a new skill I can save money I can justify buying more tools

[@onegrapefruitlover]

Same here, although I’m not sure about having saved money. I spent like $700 worth of tools to save around $50 at my local bike shop. Admittedly, those tools will continue to save me money, but it will be at least 3 years of DIY servicing until I break even 😅

[@Mylity66]

@@onegrapefruitlover you don't need $700 worth of tools, you need the tools you use for your bike/s I have around $100 worth of tools they all fit in a box and I can take apart and service everything on my bike, often, on other people's bikes as well. If you don't have an air fork, you don't need a shock pump, for example.

[@Samsonmetaphysical]

Please don't be intimidated by there being so many steps in this bleeding process. It's a lot easier than it looks, get those hands dirty.

[@G-man45444]

Gotta be honest bro.... this is intimidating. I just got my first downhiller with hydro brakes and have never serviced hyydros.... 30+ years of mountain riding and I’ve always had rimmy’s for brakes .... wayyyyy more easy to maintain but hydro discs are the sh*t !

[@consuminglight]

Found this one first, felt a bit intimidated due to seemingly many steps. Followed the Mountain bike global network one.. straight to the point and into the action. Very easy.

[@kiloindia9798]

@@oneangryme I agree that most of the time this is more than needed, but I'm really happy to have the extra steps laid out. I do my wrenching at 140 ft above sea level. My local rides max out at a few hundred feet, and I don't use the brakes for more than a few minutes at a time, but sometimes ride at 8- 10,000 ft. Brakes that work fine in the desert sometimes get quite dodgy when I get to Telluride, Durango or Big Bear without the extra attention to detail.

[@karenehrhardt8423]

It is true that not all these steps are needed all the time, but they assure a better bleed - especially if you are having trouble with the Shimano wandering bite point problem.

[@JasperJanssen]

I mean, it’s basically a fairly simple process - first push clean oil from bottom to top, then push clean oil through again from top to bottom while removing all the air.

I swear this channel has the most thorough instructions, everything else is just down to individual technical skill + experience.

[@OnlyDans848]

Lots of people (including myself) miss the point where you put a strap on the lever then open and close the bleed port. This is vital for a firm lever! If you miss this point you'll have a brake with no air but not enough fluid and pressure to give a firm feel.

[@molley17]

thank you! I've got no air bubbles left in my system but cant get my brakes to feel firm going to try this.

​@@molley17 cool! How do they feel?

[@Onigure]

I thought I had it rough with my road bike calipers. My condolences.

[@michielnooren2076]

I don't get it... First you fill up the brake line from the caliper up to lever with clean fluid. After that you let the fresh fluid run from lever to caliper into a disposal bag? Why do you do it 2 ways?

[@milanbabic92]

Haha thought the same thing. I was like what did i just watch?

[@GHinWI]

Michiel Nooren: because It’s often a bear to get all the air out. It’s an indictment of the design of bicycle brakes.

[@tubenachos]

I only do it caliper to lever. So far so good.

[@waderobinson2416]

Yeah me aswel.! find it much easier and get better results.! Its nice to flush a couple of seringes of fresh fluid through anyway and seems to get most of the air out doing that..then do the rest from the lever

[@K1989L]

Maybe you get the bubbles out that you accidentally injected with the syringe? But it does seem like a a double check.

[@bobhopeandnohope300]

Minor thing but I'd resist putting the lever bled port in the same pot as the pads. Lessen the chances of contamination.

[@reclusepilgrim]

Although a very thorough educational video, this is a tedious process and for someone like me who would be doing this once a year, the probability of meeting an accident is quite high. Therefore, I'd let the mechanic at the bike dealership do it for me who probably bleeds ten brakes in a day and, hence, has good muscle memory for the job. But I will be watching him do it and make him follow the procedures in this video.

[@michak9265]

@@reclusepilgrim I highly doubt he would do that like in this video... He will likely just push the fluid from the bottom and that's it.

[@dmarsh15]

I came here to say this

[@dcristian969]

In my humble opinion : too many tools and steps. The syringe's step of pushing oil from caliper to oil funnel could be skipped as long as the next step is gravity bleeding when you get rid of any dirty oil in that plastic bag. And I dare say it is easier to remove dirty oil at the lowest point and not the other way round. However, very informative! So thank you for your efforts

[@trinydex]

why don't people use the syringe to suck the fluid out? that leads to less mess. in the automotive world, it's called vacuum bleeding.

[@tylerseboe]

7:06 I cannot reproduce this effect with our MT7120 SLX 4 piston brakes. When I squeeze the lever, a trickle of fluid leaks out into the waste bag and air bleeds back into the system. Any thoughts?

[@TorontoPopulistConservative]

And they always cost a whole lot more than viable off the shelf alternatives. Bike tool companies make Macgyvers out of us cheap wrenchers. My bottom bracket needs a pin spanner and I'm so close to just trying out a fork with some bent tines.

[@davidb2697]

Certain lever set screws / bite point adjustment screws, when set to their maximum extent, close the hydraulic system. Find the max point as described at 2:04, then reverse a turn or two to be safe. Your shop floor will thank you.

NEVER AGAIN.

[@flashfive23]

This procedure is extremely over complicated. I feel like with all these steps there are so many things that can go wrong for new brake bleeders such as yourself. There are much simpler methods which still work quite well such as gravity bleeds.

[@danman5074]

Once flushed all new fluid in theres no reason to use waste bag. It's better to use a hose attached to syringe with top off to flush air out of caliper. As this allows drainage hose to stay submerged. This will prevent any air from back traveling into caliper and cleaning of a waste bag!

[@athomenotavailable]

Isn't steps 1-4 enough? Why Step 5 onwards? And wouldn't it be harder for bubbles to go down to the caliper?

So I just picked up a bleed kit at my local shop, but It didnt come with a syringe or tube thingy. Could I (in theory) just put the funnel with the mineral oil into the levers and squeeze them?

[@eusuntaici]

You will never get all the air out, especially for the rear brake, where the hose is longer. But truth be told, the brakes will probably still work acceptable, if you manage to make the lever feel firm when you squeeze. Just take care on the first ride, start slow until you're sure you can rely on the brakes.

Honestly while this is a great video, it's over complicated. I could see doing this if you can't get the normal version to work.

But for a total technical process, park went through literally everything.

[@somewhereonearth3049]

When exactly i need to change this oil? Pls some one teach me 🙏. How many time in one year?

[@parktool]

Generally, especially for mineral systems, just keep riding. Once every three-four years would not be outrageous. The important thing is that if the system is bleed and the fluid is dirty, be sure then to flush it out.

New brake hose installed with newish caliper and older lever. I can't get fluid to flow from the funnel to the brake caliper. What did I do wrong?

[@DG1TAL]

In order to install the new silver type of compression sleeve that is delivered with the BKM-1.2 kit now, first check if you need to deburr the edges of the sleeve. Then, apply a thin layer of silicon grease to the end of the hose to make it slide into the compression sleeve effortlessly. Kind of a Crisco situation here since the silver sleeve is a very tight fit and without grease the hose appears to be impossible to insert. Make sure you clean all excess grease afterwards in order to not contaminate your brake fluid later on.

[@robertKQ]

Great video overall with one minor problem; leaving that bleed screw in the same container with brake pads can contamine them with mineral oil...otherwise super nicely explained

[@davinglulu]

Did anyone else hear the burps??!!

[@xichael]

Are we supposed to do the bottom to top bleed (step 4) and the top to bottom bleed (step 6), or are those intended for 2 different systems?

[@galehess6676]

umm. it is way easier than using an angle finder, bleed valves, etc. just a closed end wrench, allen, bottle, fluid, some paper towels. don't need a stand or fancy junk tools like strap (just hold force with fingers), no plug needed, just suck out excess and use paper towel when removing. do take pads out, but don't sweat fluid getting on stuff (it's mineral oil, not not not dangerous. won't strip your paint or kill you) don't lose your o ring like the shop lost mine... lol do it yourself. bike shops hire ANYONE with a pulse, you can do better. don't worry about angles, just consider gravity and do the job. very few shops (none) follow this procedure, and they only run fluid one direction (which is fine). this is an easy job for a 5th grader, you can do it, noooo problem. just don't allow air/dirt into the system, keep valves closed when appropriate.

[@kcyclopoints]

Thank you

[@Gwimpin]

Great video. I have been wondering why not to use syringe attached to the caliper to create little vacuum in the system and get oil from funnel at the lever to the caliper instead of just pushing the lever and opening bleed nipple?

[@JasperJanssen]

Because you already have the lever on that side as a pump. And because syringes don’t pull a vacuum very well and if they did it would cause bubbles, rather than bleeding them out.

[@Matt-x5c]

May I ask what is the point of the last step: Holding the brake lever with a cable tie and rapidly opening and closing the bleed nipple?
