Squeaking front brakes SR'16
on: December 25, 2021, 03:00:25 PM
Hello, guys!
On 12000km I've changed front brake pad's - they were almost at min thickness, but I suppose should last about 2-3k.km. And they squeaking.. a lot..
So, I installed genuine pads and after 100km situation repeat...
Then I dismantled front brake system, use LM brake pad grease(blue one, which remove vibration and squeaking), and everything were fine for an about 500km....

What the hell? Does anybody has same issues with brakepads or discs?
Bike mileage now-15000km

Try cleaning your rotors as well, pad material can build up on these as well. Brake cleaner and a scotchbrite pad

Did it, no results.
It seams like brake disc has small deformation, but according to micrometr- maximum deviation ondifferent measured points-0,02mkr

If you've done all the usual things, I would suggest you loosen the caliper bolts a bit....apply brake pressure with a bungee or with the assistance of a helper, and then re-torque the bolts with pressure applied.

Good shout, I do this with my mountain bikes so should also work with a motorcycle. I would also deglaze the pads with fine wet and dry and clean the discs with fine wire wool and brake cleaner.

Sound advice even on bikes with caliper locating pins like ours. Helps to ensure everything is centered and seated well. I would also check to make sure the pucks are all free and actuate properly. If one is stuck, it can cause a variety of problems.

Do it, but I've loosen it not a bit... a half way out I guess...
