If you hear a grinding or squealing sound when the pedal is applied, you probably need new brake shoes or pads. Brakes shouldn’t make any noise as they operate. Even if the actual problem turns out to be something minor, the only safe assumption is this one: noisy brakes are unsafe brakes. Postponing service is unsafe and could raise the cost of repairs later. If your brakes are making noise, get them inspected or serviced right away.
