Rear Brake Pads in Vantaa

When rear brake pads need replacing

Rear brakes typically take only 20–30 % of braking force, so their wear interval is usually twice that of the front pads. Even so, the rear axle has a major effect on the car's balance under braking — worn rear pads cause swaying or pulling to the side, especially on a wet road. Modern cars usually have an electronic parking brake that is integrated into the rear caliper. As the pads wear, the piston is extended by a small motor. During replacement the piston must be retracted using only the manufacturer's diagnostic tool — otherwise the motor can be damaged. Regular inspection is important because rear brakes can seize or corrode if the car is only used on short trips where the pads never heat up properly. That accelerates wear and can suddenly damage the discs.
