Thanks Dave for sharing those interesting facts and maintenance advises , i recently got a low milage bike and the previous owner did a powder coating to the wheels that damaged the front wheel hub and i realized that after i got the bike , the bearing are not snug in the hub, i didn't want to get a new wheel and was thinking of fixing the one i have, one interesting solution that i didn't try yet is to use loctite 609 (green) for the bearing to make it fit into the hub, i'm planning to try that but was looking for some advises from you as i didn't find many people sharing their experience with such problem.

Correct, maybe the missing spring plates are the reason that the pad pin is damaged like that (I have a K3 as well).

Very nice video and thank you for commenting on the previous post about pad deposits on the rotor. I have a question that no one has been able to answer about those Brembo monoblocks. I had some trouble with a GSXR master cylinder 2 years ago and while troubleshooting it I cleaned and replace o-rings in the calipers. During this process I found out that the inlet hose and the bleed screw are not separated internally. Both holes go into the same cavity. Because of this, while bleeding the fluid, the new fluid simply travels down the hose, into the first cavity and then out the bleed screw. It does not travel around the pistons and therefore the old fluid around the pistons does not get flushed. The only way to really bleed these calipers effectively (which, to me, is defined by saying at least 90-95% of the old fluid gets pushed out) is to pull the pistons and drain the calipers each time. What am I missing? This just seems like a really ineffective design.

You are not missing anything. Your observations show how the flow path works and these brakes are designed to encourage frequent cleaning as they are "race" type calipers that get a lot of attention as per several of the old On The Throttle brake cleaning videos. It can seem odd, but knowing what you have and how best to service it is by far more important.

Hi Dave, what is your suggestion when putting new rotors in, out of the box? I just replaced mine and cleaned them with brake cleaner. Also my pads are new but they have done one trackday with the old rotors. What is the best way to make them work together? Is the pad now formed to the old rotor, even after a session?

@catalystreactionsbw

I follow the manufacturers suggestions to the letter. If you do not have those, email them and acquire them. General rule of thumb if you have no information is 30mph to a stop with constant 50% pressure, repeat 20 times so you get pad material on the rotor. On track session light prolonged braking in normal braking zones (essentially drag the brakes). Next session more pressure, shorter duration. Third session 80% to start, 90% from half way through to end. Last session, regular pace, normal braking skills in brakes on and off areas.

Hi Dave ! How would you clean the break pistons if that was necesary ?

@Ducati_Dude

6 жыл бұрын

Sebastian Cichy ---> An efficient and simple way to get caliper pistons clean is to make a wood block about a half inch thick by about 2 inches long and 1 inch wide. These dimensions worked well for my Brembo M50's, however not all calipers are created equal. So you may have to modify yours a tad to fit your application. Once you have your wood block ready, place it between the caliper pistons. Now pump in some brake fluid to move the pistons out so they bite the wood block. The pistons now have good extension and will not fall out. So... now you have to clean the dirt off the pistons. A toothbrush is a great cleaning tool, but a better way (and gets 100% of the dirt'n grime) to clean your pistons, is to use shoe laces. I like to use white shoelaces so I can see the dirt being removed. Spray some brake cleaner to a section of your shoelace. Using the end of the shoelace, push it into the caliper and thread around the piston and back out. Now slide the shoelace back and fourth on the piston side. If you cross-over the lace, as you are sliding it, you will get 100% coverage. You may need to use a few different sections of shoelace before your piston is perfectly clean. Cheers!!!

Great question. This is normally don when you remove the line from the caliper to clean it or disassemble it. With bikes there is such a small amount of fluid lost in a very short line (comparatively), there's no reason to pinch the line. That's my 2 cents.

Hope you have a video comprehensive as this do fluid removal / change ….this was so much easier to follow for me ..maybe because I always do my own car brakes …..but am guilty of Basically never changing brake fluid ,most I’d do is during bleeding running old fluid through till new ( or looks mostly new ) fluid bleeds..

Maybe stupid remark. When talking about „stainless“ steal the German MOT allows only A4-80 stainless steal (not the cheap A2-70) or titanium at the braking system (including calliper fixing bolts), because A2-70 is not „flexible“. It will break instead of bend. Same thing with bolts at the suspension system. Which makes sense to me.

Don't you need to open the lil bleeder valve while pushing the pistons back?

@catalystreactionsbw

4 жыл бұрын

You do not, the brake fluid pushes back into the reservoir BUT you have to make sure there is room for the fluid to do so!

A lot of grit gets trapped in the array of holes in the rotors. What I do is spray the outer surface all the way around first, with a paper towel behind. This is better than using an airline which can send debris everywhere. Then I clean both surfaces, poke every damned hole, and wipe the surfaces again. It’s laborious and time consuming, but grit is as unwelcome as grease on brake pads. I also avoid cross contamination by changing my gloves regularly and after each filthy stage. Another trick with the pins is to spin them in a drill (wrapped in tape to protect them from the chuck jaws) and clean the dirty/rusty/uneven surfaces using 400 grit taped onto a 1.5” wide x 6” long piece of thin flat plywood. This gives you light annular effect around the diameter - which we don’t want. So then I wank the buggers with 800 grit until the annular marks are removed, to create the desired longitudinal lines instead. I even finish off with 1600 grit to really polish them beyond smooth. This has the effect of preserving their useful life by creating a surface that’s far less likely to attract moisture, so less likely to corrode. Finally, I sometimes find that swapping pins around offers different areas of the pin surface to the part of the pad backing plate that wears the pins, thus effectively starting again with a similar situation as when the pins were new. When needs must, there’s nothing quite as satisfying as returning brakes to like new operability without spending any money, particularly useful when working on older bikes.

19:22 those original pads are mismatch between left and right. Someone wasn't paying attention when fitting the leading edge with direction of the rotation. Or is this just the OCD in me? But the mechanical knowledge of rotation and attack of the pad should have the longer section on the pad to the leading edge. This will result in uneven braking between the left and right side of the single disc that can heat the disc uneven also and warping the disc. It can also result in uneven wear of the pads and loss of braking power.

Not quite, they can be tough anyway because of the fluid, but it would make sense to clean them first for the reasons you state, no need the rebuild the caliper just to do that. A bit of soapy water and a toothbrush will clean them enough to reduce the risk of causing damage, it is rare though, I bet they had no issues, at least for some time.

cleaning the disks .. make your own sandblaster .. costs about 10 bucks to make

Before you open the caliper, clamp the brake line with a brake line clamp (very cheap) and open the bleed port and place a hose on the nipple to control where the contaminated fluid goes (into a drip pan of course) .... THEN open your caliper. Doing this pushes all the dirty fluid OUT of the system. If you do it the way shown in this video, your pushing contaminated fluid back to the reservoir. The main cause of caliper failure is contamination. NEVER PUSH OLD FLUID BACK INTO THE SYSTEM. Always out!
