Back brake rubbing

[S0ldier]

Hello all

Got a problem, think it ties in with £45 boots I got off amazon which are totally solid plastic, made back break seem way sharper

I've noticed now although the back break works there's a continuous rubbing/grinding all the way round, the disc isn't warped or anything.

Is there a simple way to loosen it so it's not rubbing off disc ?

Any help hugely appreciated

Cheers

May just be grub in the caliper meaning piston not fully retracting and pad rubbing.

Try cleaning it properly (maybe with brake cleaner ) and see if sorts. If not may need a caliper rebuild
