Buick vehicles all come with entrance disc brakes that integrate brake calipers, pads and rotors. Some of the newer entrance-wheel drive models might also characteristic rear disc brakes as an alternative of drum brakes. While changing calipers is not a standard brake repair, it is required to take away them as a way to change pads or rotors. The rear brake calipers on Buicks combine the parking brake cable. Because of this, there is a slightly completely different process set up them than the front brake calipers.

Buick Brake Calipers Installation Instructions

1. Remove the hubcap(s) if applicable and loosen the lug nuts with a tire iron before lifting the wheel(s) you plan to install the brake caliper on.
2. Elevate and help the wheel(s) of the Buick with a jack and jack stands after which take away the lug nuts and wheels.
3. Place the C-clamp over the again of the caliper housing and the drive of the clamp onto the backing plate of the outboard pad. Tighten the clamp to compress the caliper piston.
4. Pull down on the parking brake cable (on the rear calipers solely) after which take away the cable from the cable connector on the brake caliper.
5. Place a drain pan under the wheel the place the brake hose attaches to the caliper.
6. Place a brake hose clamp onto the brake hose just a few inches away from the place it connects to the caliper.
7. Remove the brake hose bolt from the brake caliper using a ratchet and socket or a box-finish wrench. Be sure you take away the old copper washers from each side of the brake hose bolt.
8. Remove the 2 caliper guide bolts with a ratchet and socket or a field-end wrench (entrance calipers solely). Take away simply the decrease bolt on rear brake calipers and then pivot the caliper upward to slip it off the higher brake caliper pin bolt.
9. Remove the caliper anchor bolts if desired. Some replacement calipers include the caliper anchors whereas different do not. Only take away the anchor when you’re replacing the anchor or the rotor.
10. Set up the new caliper by reversing the procedure. New brake calipers will come with the pistons compressed. Remember to exchange the copper washers on both sides of the brake hose bolt and reattach the parking brake cable to the rear calipers
11. Open the bleeder screw of the new caliper till a gentle trickle of brake fluid begins to purge from it. You’ll want to align the drain pan to catch the fluid. Take away the master cylinder cover and check the fluid often so it doesn’t run out of fluid. When a steady trickle is achieved, tighten the bleeder screw, top off the master cylinder with new brake fluid after which replace the cover.
12. Make use of an assistant to rigorously get into the Buick and pump the brake pedal 4 to 5 times. While the assistant is holding pressure down on the brake pedal, reopen the bleeder screw to purge the air from the brake lines. Repeat this process until the brake pedal feels agency and the brake fluid lacks air bubbles. Prime off the master cylinder with new brake fluid again after which change the wheel and lug nuts.
