Author Topic: pad contact with rotor and floating type rotors (Read 2514 times)

Is it normal for the pads on the front brakes to be in slight contact with the rotors even when the brake is not applied?

Also, I hope this is not a really stupid question, but what are floating type rotors?

Thanks

I think it's fine as long as you can spin the wheel by hand when its on the center stand.

Yea, it spins by hand without stopping immideatly. But it has drag on it from the brake pads. It's enough drag to hear though and that's what worries me. I never tried to spin the wheel by hand before I took it off so I have nothing to compare too.

I read on another site that's for automotive questions that the pads are always in contact with the rotors so the braking is instantaneous. So hopefully that applies to bikes also.

Thanks for responding

Light contact is typical for motorcycle disc brakes, too.

This is the only kind of disc brakes I've ever seen that don't have contact between the caliper and pads when off.

So far, I've only seen these kind of multiple discs on a single wheel systems on large aircraft.
