How to Replace Saturn Rear Brake Pads

The Saturn line of automobiles is manufactured with rear disk brakes which contain routine maintenance parts that must be replaced at regular intervals. The rear disk brake pads have a friction material that can wear down after 20,000 to 30,000 miles, and will produce a loud squealing sound when they are at the end of their lifespan. The average backyard mechanic can replace the rear pads on a Saturn in about an hour.

Instructions

1

Raise the Saturn onto the jack stands with the floor jack, placing the jack stands solidly onto the frame rails.

2

Remove both rear wheels by turning their lug nuts counterclockwise, then setting the wheels and tires away from the vehicle.

3

Remove the two rear caliper bolts by turning them in a counterclockwise direction. The caliper will slide off of the rotor, or can be lightly pried off with a screwdriver.

4

Replace the pads on the caliper pistons by pulling an old pad free, then positioning a new one in its place. The pads are not usually clipped or connected to the caliper piston. Quickly slide the caliper back onto the rotor, and don't allow the caliper pistons to close too much or they could be difficult to press back into place.

5

Replace the caliper's rear mount bolts, turning them clockwise.

6

Bleed the caliper and brake lines by turning the caliper nipple counterclockwise, then adding more brake fluid to the master cylinder (in the engine compartment) while pressing the brake pedal. Close the nipple in a clockwise direction when the air is purged from the line.

7

Repeat Steps 3 through 6 for the opposite brake pads.

8

Replace the wheels by turning their lug nuts clockwise, in an alternating pattern. Lower the Saturn from the jack stands.
