Step-by-Step Brake Pad Replacement

Modern automotive disc brakes are reliable, effective and simple to maintain. All brake parts are easily accessible, and the function of the various components is easy to understand. One of the most frequent routine maintenance requirements on a vehicle is replacing the brake pads as they will wear out over time due to the friction generated in the braking action. Vehicle owners can save both time and money by learning how to perform this routine service themselves.

Instructions

1

Park the vehicle on a level, paved surface. Block the front wheels if you are working on a rear brake and block the rear wheels if you are working on a front brake. Loosen the lug nuts about one full turn each. Raise the vehicle with a jack and set it on a jack stand. Finish removing the lug nuts then pull off the wheel.

2

Unscrew the lower of the two brake caliper bolts with a wrench. Rotate the caliper upwards around the upper bolt as far as it will go and secure the caliper in this position with a bungee cord or piece of wire.

3

Remove any retaining clips that hold the brake pads in place, then remove the old pads and shims by sliding them towards the center of the caliper frame until they pull free.

4

Hook a large C-clamp over the back of the caliper frame and place the spindle of the clamp onto the piston face. Tighten the clamp to push the piston back into the cylinder.

5

Install the new brake pads and shims, then reinstall the retaining clips.

6

Rotate the caliper down to its original position and reinstall the caliper bolt.

7

Remount the wheel with the lug nuts. Raise the vehicle and remove the jack stands then lower it to the ground with the jack. Start the engine and pump the brake pedal until it feels firm to extend the brake piston.
