Accordingly, what causes glaze on brake rotors?
Glazed brake pads: The brakes have been heated up to the point that they become hardened and are no longer create enough friction on the brake drum or rotor. This condition can cause the Performance Brake Pads to make all kinds of noises, from squeaking to grinding. It will also reduce braking performance.
Beside above, what causes rotors to get hot? When you drive heat is generated in the caliper which causes the brake fluid to expand. Normally this expansion is accepted into the master, but if it is over filled there is nowhere for it to go so it pushes the calipers piston out which creates excessive friction between the brake pads and rotors.
