The metal rotor that the brake pads squeeze together can sometimes vibrate, causing a squeaking noise. Luckily, there are several ways to fix this: 1  Use a milk spray, lotion or cream on the back of the pads [source: Allen].  Use sandpaper to sand off surface hardening of the brake pad/shoe surface.
Continually driving a vehicle until the friction lining of the brake pads is worn away will lead to expensive damageâyour brakes might even fail. Anytime the brakes make an abnormal noise, they should be inspected and repaired before the braking system becomes compromised in any way.hen the brakes are applied, the brake pads put clamping pressure on the brake rotor in the same manner the rubber brake blocks come into contact with the rim of a bicycle. The pressure the brake pads apply to the brake rotor is proportional to the pressure applied to the brake pedal by the driver's foot.
