Front Brake adjustment question
« on: May 07, 2019, 12:44:41 PM »
I am having some issues setting up my front brake. I have adjusted it according to the manual so wheel spins freely but then when i squeeze the brake it seems to be binding.

I have checked and lubricated the swinging pivot and this is all moving freely so I cant understand why the brake is binding all the time.

Makes it a hard job to back it out of the garage as well!!!

If you think there's light at the end of the tunnel it's usually another train !!

Usually caused by the seal sticking Paul, the groove it sits in can get clogged with crap and it affects the way the seal distorts as the piston moves out, this means it hasn't the power to pull the piston back and the brake binds as a result, you need to check the piston seal and it's groove and replace if needed.

Thanks will do

Also there are 2 holes at base of master cylinder HONEST the one that doesnt look like a hole is TINY cleaned with 2 strands of multicore electric flex twisted together.
Very occasionaly the flexies go bad and collapse letting fluid through but not back.

Hopefully all fixed, turns out the pad was binding in the cylinder when I stripped it down but piston seemed fine.

Cleaned up all, emeryed around the metal on the pad back and made shire it was free in the bore and then applied some copper grease on reassembly, new fluid etc and all now fine
