How do I stop my bike brakes from rubbing?

What causes brakes to rub?

Worn-Out or Poor-Quality Brake Pads

Lack of proper brake caliper lube or missing shims between the brake pad’s backing plate and caliper piston will cause them to rub against one other, causing a grinding noise when stopping (as well as rattle while driving).

Why does it sound like my brakes are rubbing?

A rubbing sound could be an early sign of a worn brake pad rubbing against the rotor. The pad could be in an early stage of wear before it moves on to a heavy grinding noise. Another possibility is a braking pad that hasn’t fully released. If you haven’t driven your car in a while, there may be rust on the rotors.

Why do my disc brakes rub when I turn?

Probably one of the pads is very close to the disc, so when you take a turn the rotor rubs the pad because of the deformation of the frame/fork and wheel under lateral load. If the frame/fork/wheel are not stiff enough you’ll experience this no matter how centered the rotor is between the pads.
