BRAKE ROTOR & PAD FRICTION HOW TO PREVENT IT...????

Even when the brake is not engaged how do you prevent the brake pad from rubbing on the brake rotor...????

Is it tight on the rotor, or just lightly riding on it? Your caliper could be sticky, notched brake pad pins?

I did a complete tear down on my caliper, jackshaft, and rotor. Smooth as silk now, no rubbing at all. Thanks for posting

Simple answer is you don't. There is no force to move the pads apart in a brake caliper. As soon as the force is released, the pads stop "squeezing", but they do no move back at all. Or at least less than a sheet of paper's thickness.

You wouldn't want them to move away since the small amount of fluid pushed by the piston on your brake lever only moves them in a tiny amount. The tolerances are supposed to be very close. This is why a small air bubble in the line makes for spongy brakes.

I hope I understood your question properly.....
