So i changed the front pads of my sportbike..introduction: (at beggining the front brake lever was too low almost touching the handle to brake. When i changed the new pads, nothing really changed so i put a little top inside the regulation of the lever just to put it upper, so when i brake dont go too down )the problem.So after changing the pads, the bike got really braked,the wheel dont turn, and after a while it virtually stopped the bike too sudden, and got overheated on the disc rotors..i had to bleed them but after a little ride it happens again the bike brakes itself, and become really hard.the funny thing is that overnight the brakes got released itself and the wheel turns again.. until i brake a couple of times when it gets stucked again..What is it =(what i did wrong?whats the solution thanks!!mech experts 10 pts.
Disk brakes aren't worth a flying f*() after about 5 years. Things get corroded and don't release.
My guess is that the seals inside the caliper cylinders have picked up so much dust that it has jammed the pistons, you will need to completely strip down and service the caliper and replace the seals – do not scratch the bore.
I have had this happen before. What has happened is that the pistons which push the brake pads have come out of the caliper too far, and jammed. You can pull them out and clean them up, which is ok if you have the time, inclination and tools. I have done it before, but last time I put it into the shop and I think it was $160 to fix.
Like someone else said. The piston is stuck in the bore of the caliper. Had a bike come thru a few days ago with the same issue. Duel caliper fronts and the left one frozen solid. Put 170psi of air to brake free. Nothing. 170psi should have shot that piston a cross the parking lot and down the street.
Hi dude the brakes works with the gradual engagement so you gotta check the cylinder and play if everything fine ,,check the caliper and the piston inside the caliper i guess the gap between two pads has increased so it might touching the disc and causing too much friction and when you apply brakes the brake pad which is already in tightly packed and causing continues contact with disc causing faster engagement which results wheel lock ,,so bleeding won't work it's just to remove the air bubbles ,all you gotta do is meet a mechanic and reset the brake pedal play as well as the Brake caliper
