[@FranBunnyFFXII]

You guys don't carry the Galfer Rotors I used for my bike. So I had to grab them from FuelMoto USA. :

[@ChristianNeff]

Only thing I would have liked to hear Ari comment on is Buell's design with the rotor on the outside of the rim. I remember reading about it years ago and it sounded like a pretty solid improvement for brakes. At least in street applications. Great video as always though!

[@yobkit1982]

i thought you guys were gonna discuss the potential danger of floating discs. not sure what would cause the floating discs to push the pistons back causing no brakes for few pumps until pistons are back to where they should. never knew this could happen until a rider at my local track died because of brake failure. he had a tank slap and as a result, no brakes. not entirely sure what the exact explanation but according to other riders, tank slap caused the floating discs to push the pistons back. this is quite uncommon, i would really appreciate if you guys can explain this in detail.

[@EarthAmbassador]

@@yobkit1982 This happened to me on my R6. Didn't know it was caused by the floating rotors though. Got a tank slapper and then didn't need my brakes until I was coming up on a hairpin. Luckily I was taking it easy after the tank slapper and had time to mash my brakes until I got some breaking action back. Scary stuff.

[@theladdiesda8190]

​@yobkit1982 the floating disks vs non floating don't make any difference in terms of pushing pads back after a tank slapper. It happens either way

[@andrewince8824]

Not a motorbike guy but I'm an MTB fanatic. We have this argument all the time. Floaters say "but heat dissipation, weight, looks pretty" while solids say "budget friendly, simple". Some of you may not believe it but on a good DH run discs get hot, even on a push bike. They will offer burns and boil the rain. As a result, floaters are becoming more popular and we're seeing DOT 5.1 brakes becoming the most in thing with Hope and SRAM being incredibly popular choices. With that said, the simpler and less maintainance heavy mineral oil brakes have picked their game up, both Magura and Shimano have really upped the formulas for their mineral oils while ensuring they won't hurt older models. My initial thought going into this video was, "yeah, obviously a 200kg bike doing 100km/h and over will want floaters, those beasts make a brake glow". Just like MTB, solid discs on motorcycles seem to be a budget offering or a lower performance offering. It makes sense, sure a set of £50 Tektro solid rotors work but a pair of Hope floating rotors at £100 a pair do it better, seems very intuitive that as speed and mass increase, that superior performance becomes less of a desire and more of a requirement. Overall a very informative video and very well produced. No guff, no gimmicks, just pure information and some beautifully engineered examples, I wish MTB had discs as sexy as those.

[@Jagknorr]

As someone whose only gotten into bikes in the last 5 years, videos like this are super interesting. Maybe not something i think about when im working or riding my bike - but very cool to know all the advancements we have made over time.😁 Also just general bike knowledge is crazy helpful!

[@SmallSpoonBrigade]

If you want something to blow your mind, stainless steel brake hoses. I replaced mine a couple years ago and the cost was roughly the same as the OEM rubber ones, but they'll both last much longer and they give much better feedback to me while I'm braking. Plus, the fact that I was able to get one that matched my bike's paint scheme was an added bonus. Those things look and perform amazingly.

[@Showmetheevidence-]

@@SmallSpoonBrigadethis is one of the absolute best mods ever. I’m actually surprised almost no bikes come with them as standard.

[@aTuWitty]

THANK YOU. I can't believe the number of posts on bike groups where someone will show their discs from a street bike and there will be lateral movement, and SO MANY of the replies are "it's a floating rotor, it's fine bro". NO. Full-floating and semi-floating are different and when your semi-floater becomes a full-floater, that's when it's time to replace it. Thanks for giving me my new go-to video on this topic!

Would be cool to see a video on maintenance of semi-floating discs, especially for people who live in cooler/wetter climates.

[@curbkreature7488]

What maintenance? 👀

[@HalfdeadRider]

@@curbkreature7488 Over time the rivets can get dirt and corrosion in them seizing them up, you can also replace them if damaged or badly corroded.

[@HalfdeadRider]

@@curbkreature7488 Also good maintenance of brakes include using fine sandpaper or scotch brite to clean old brake dust from the surface of the discs themselves.

[@DylanGSXR]

Best way to do it is to make sure you keep the bobbin/ rivit free moving . Use a 10mm bolt and nut out through the hole and turn it clockwise and anticlockwise to keep them free moving . Do this once a year ..I would not bother with sandpaper on rotor unless you are installing new pads as they work better with your pad material on the rotor/disc . Caliper maintenance is so important and lots of videos on KZbin about it .

[@Astrix_Jaeger]

Basically your brake system is a heat converter. I like that explanation, easy, simple, and understable.

[@RIDER500ful]

Abosolutaly love this series. "The Shop Manual" is the only reason I had subscribed to this channel. Unfortunatly though, I dont understand why you guys started bombarding our subscription feed with riding-gear review videos which no one is interested in (reflected in views of those videos). I then had no option but to unsuscribe. Please make more of such great informative videos and less of riding gear videos. There are millions of riders like me, who wants to learn more about their bikes but aren't interested in any of those gears you review, simply becuase we don't live in USA or Canada.

[@noophe5747]

I had worn pads thinking that was my issue with braking performance. Put in a new set and has the same issue, low performance braking with some pulsing. Also found them to wear out incredibly fast Ended up having sand in the rivets and my rotors become solid. Cleaned them out and it's all back to normal

[@jayzee7603]

I Have been watching this guy since 2016 on motorcyclist, good to see he is still doing great!

[@T30-z5w]

I noticed one of my front rotors on my adventure bike was very lose. Upon inspection I saw that three rivets had bent flanges. This likely happened during an offroad steep and slippery leaf filled ditch mishap years ago. Took some work to flatten the rivet flanges back on the affected rivets. Bottom line, if you’re off roading with a bike with floating rotors keep in mind they’re more delicate and can be easily damaged from lateral forces.

[@FranckSonata]

This is goood. I don't delve into MC related stuff that much nowadays (despite having 269 HP bike power in the garage) but when the quality is superior (or there is lovely recorded exhaust sound), I listen. This seems to be a superb channel.

[@KibberShuriq]

> the rivets that secure the rotor to the carrier are either clamped right out use spring washers I've read somewhere that when the rivets are clamped tight (without spring washers), heat expansion of the rotor can actually cause it to break the rivets - since tight rivets leave no room for it to expand. That problem is unlikely to happen during normal street riding, but then you don't really need floating discs for street riding anyway.

[@viciadoR3]

My '04 Vstrom has these types of semi-floating discs. I've always wondered why, it's nice to know now. Awesome content.

[@CubanRider]

The absolutely best video I've watched on the subject. Ari these videos are an incredible resource, huge props to you and the team. I've been tracking my heavy BMW on solid discs for years now, braking from 155 mph to 40 at COTA in the advanced group, I'm surprised how well my rotors have held up. Definitely looking to upgrade to semi-floating rotors soon!

[@AntaresSQ01]

Nice to see you here 😄but actually BMW's front discs on the XR are semi floating. They are still mounted on bobbins and have play in all directions, simply the hub is not present as the wheel takes care of that. No real reason to upgrade to anything different.

[@CubanRider]

@@AntaresSQ01 oh wow, I just went to the garage and checked. They wiggle for sure! Amazing that after all these years I'm just learning this. Thanks!

[@BrickHouseBuilds]

Absolutely EPIC video! This had to be so dang hard to record and catalog. Great work by Ari and editing team!

[@tudajfor]

And let's not forget the cool cooling effect the semi-floating rotors get when you stop, and that is the legendary popping sound of the rivets singing while cooling down :D Best sound ever to boost ones ego for going toooooooooo fast :D

[@arthurjennings5202]

Decreased unsprung weight has several benefits as well. Way back in the day, I rode a Suzuki GS850 shaft drive motorcycle. The original tire was a Dunlop. A Continental tire of the same size and rating weighed about 5 pounds less. That helped reduce the unsprung weight penalty of the shaft drive and made the bike much more controllable on rough roads. The Suzuki also had two steel front rotors and it would have been nice to dropped 8 pounds of unsprung weight on the front wheel as well. But, didn't have technology then.

[@OG_Mereles]

This show never disappoints. Great job guys!

[@gruntmax43]

I had a set of PFM Brakes, full floaters & discs are cast iron, not stainless, which cool a lot quicker. Replaced the discs & rebuilt the 2 x 6 piston calipers when I sold the bike @ 120,000 klms. Discs had about 80,000 klms & needed replacing due to wear. Bike was a 1580cc Big Block Stroker Motor Gen2 Hayabusa. I'm the inventor of the Thermoelectric Boost Cooling & Charging System. Just click on the avatar & enjoy the ride on the 2019 Kawasaki H2SXSE+

[@1darryloflife]

Wet discs have been around a long time but due to corporate pressure they are not an option due to the length of time between pad changes, but the wet disc is the clear number 1 form of braking as it allows the best control of the braking and the best stopping distance . Macpherson tractors were the first to invent the wet disc , housing the disc brake and caliper in a sealed container filled with hydraulic fluid and the pad had a 10mm wide groove cut into the pad allowing the fluid to flow through the pad whilst the pad was being forced into the disc rotor.

Hey Ari, can you please do a breakdown of what “backing it in” is and and if it’s bad for your bike? Thanks!

[@sirjolly81]

do it all the time on my mt09. learned on my husky te510 motard and xr400 motard. Its fun sliding the back out when entering a corner.

[@crisnmaryfam7344]

"Backing it in" usually refers to diving into a corner hard with the rear end loose because you were so heavy breaking that the rear wheel is traveling faster then the front. This is also the same/similar to in Drifting they call a "rear entry". They again, dive so hard into the corner the car rotates to the point of the front being behind the rear for a second or two as the car spins the rear wheels to regain control.

[@crisnmaryfam7344]

as for bad for your bike... Not "really", however, doing anything this dramatic and hard on the components is going to cause wear and tear, so in a way Yes, its bad for your tires, brakes, suspension and possibly for you if you mess up and cause a high side and throw yourself off like a motogp racer in the rain.

[@fabiopunk1661]

good and clear as usual, top marks. I have solid discs on my 1985 Moto Guzzi, for the type of rides I do with that (long relaxed tours, loaded) the braking power is OK but I have had issues. Even after precision grinding, wear pattern is not uniform across the disks. I guess it is a matter of mounting tolerances (disc to wheel to fork to caliper). I have floating disks on my 916 and that is entirely different world....but of course these two bikes are at the opposite ends of the type of utilization

[@firstmkb]

Thanks! Saw an auto video last week with floating rotors on an AMG, and didn’t know what they were talking about.

So very interesting that just yesterday I was looking at my bike and considering my floating disks and how very far we’ve come since I first started riding sports bikes back in the late ‘70’s, brilliant leaps in technology with this definitely not being the least. Maybe a general tech comparison between the two times would be interesting, brakes, carbs to injectors, fluids, tyres, there’s been quite a bit in my time.

On the track, I could fet fade from quite fancy front discs within a few laps (the rear brake is not really a track "thing" with motorcycles). However, using hydrailic discs on an MTB I have never sifferwd fade, even over a hard and long enduro with long, steep descents.

I think for ordinary road use a solid disc lasts way longer especially without the holes . There seems to be an industry hell bent on making brake discs a renewable service item . I am on my third front semi floater after 80k miles , a colleague on an older beemer is 200k miles on original disc with no signs of wear still . The trick with solid discs is to not leave your brakes on after a very heavy stop to help avoid a hot spot and warping , common on many cars also .

[@Lucky-ec8xo]

Thanks. HElpfull also in context of mountains bike discs breaks.

[@markpapp8784]

Something rings a bell here... IIRC, fully floating discs caused an unpleasant accident at the IOM TT (quite) a few years ago. At the end of a looooong flat-out-fast and bumpy downhill section of the circuit the rider went to brake and found nothing. The floating disc had had enough lateral rattle to have knocked the pads and pistons a mm or so back into the calipers, so when the rider squeezed the lever all he did was take up the slack. By the time he squeezed again there wasn't a lot of braking zone left. Again IIRC, everybody stopped using fully floating discs at the TT after that. I don't know if there was a rule brought in banning them or whether they fell out of favour. As I might have mentioned, it was a long time ago.

[@chipy1521]

This was a great video. Extremely informative without too much jargon or feeling as if you’re being thrown all this information.

[@10fantic]

More! More! More! Miss ya guys and your shop videos ❤

[@hinterlands]

One point that I think was overlooked. Solid discs allow the heat to soak into the surrounding wheel hub and assembly. Floating discs don't have this type of heat dissipation path. Generally on the front of a bike that isn't a problem. In go karts as an example, floating discs can overheat more quickly than solid disc because of the location of the disc behind the seat, its nearer to the engine and the disc carrier and rear axle provide a great heat sync.

[@YouMotorcycle]

Great vid, as always Ari

[@BikeStandByMe]

Agreed the floating rotors are far superior but I had a bmw 1150rwith a solid rear rotor and never experienced any brake fad. On the other end of the spectrum I have a Ktm 1290 with a floating rear rotor and boiled the fluid. 100,000 miles on the bmw and about 20,000 at this time on the Ktm. Not sure why, I don’t drag the brake and have not changed my riding style. Both are Brembo as well. Just my personal experience.

[@JohnThomas-zg8kf]

Nice Vid, but what did you mean at 3:50 by "Pad separation"

[@ldnwholesale8552]

There is 3 types,, solid rotor, alloy hat and iron rotor and then alloy hat and floating rotors. For budget racecar stuff the alloy hat and iron rotor is common. They do not float,,do have some of the issues you mention but also have less issues of rotors running out, and cracking from the bobbin holes I have used all 3 types. For racing a solid rotor is the worse. But only with extreme heat. A little care required For top level racing a floating rotor is preferable,, for the rest an alloy hub resolves most issues and are a good deal cheaper as well

[@johndavidwolf4239]

1) You said that the "non-aluminum" was "steel", My recollection is that cast Iron, has better thermal, frictional, and 'non-warping' characteristics than steel, although some bikes now use "stainless steel". 2) Why would "floating" disks run cooler? I would think just the opposite as the inner metal on one piece would act as both a bigger "heat sink" and also conduct more hear to the hub, which in theory is bad for the wheel bearing grease, but that is another issue.

[@jacobclark89]

Stellar vid ! please help me to get the word out about a serous flaw on many china floating bicycle brake disc ive tried several brands and they all have super thin cheap steel washers that can rust out in no time , when they must have stainless !

Question: AT 3:47 you mentioned "risk of pad separation." I wondering what that means? The reason I ask is that I warped the stock front rotor on my Ninja 400 during a track day, so I replaced it with a Brembo rotor that is apparently "full floating" because it has all that lateral play (and rattles as you describe). You mentioned this type of rotor is not ideal for street riding so I wonder what's the downside, other than the rattling? Because I also ride this bike on the street sometimes. Thankss

[@yngvehafting6828]

Thanks for great content, but i have one question: @3:27 What are the variety of reasons that fully floating disks isn't ideal for everyday use? I mean except for the sound, isn't a fully floating rotor much easier to clean? On my semi-floating Brembos getting rid of debris seized in the rivets is a pain every rainfall. With significantly larger tolerances I'm assuming that would be much less troublesome. Id like to know why i should not go fully floating because right now it seems the obvious next step, even though my use far from performance oriented (Ive been to track once, but ive had warped disks changed and I can feel the difference when dust is seized in the rivets on normal days).

[@KibberShuriq]

Besides the noise, the freeplay in fully floating disks means they wear out much faster around the buttons, and wear out the buttons as well. Dirt and grime from the streets increase that wear even further.
