Question 1

How to replace the front brake calipers on Buick LeSabre?

Accepted Answer

When inspecting brake fluid levels, check if the reservoir is midway between max and min lines because this indicates no fluid needs touching except when exceeding the midway mark during fluid level reduction. Place the vehicle on stands and take off the tire and wheel parts. Secure the large c-clamp across the brake caliper with your ends touching the caliper backside and outer Brake Pad surface until the caliper piston moves beyond the brake rotor. Untighten the c-clamp before disconnecting the brake hose from the caliper bolt and eliminating both copper brake hose gaskets that may adhere to the caliper or hose end. Before removing the brake caliper, seal its openings to keep fluid inside and clean and unscrew the two brake caliper bolts (1, 2). You should clean and dry brake caliper pin bolts and retainers with denatured alcohol and filtered air that does not contain lubricant. Put high temperature silicone brake lubricant only on the pin bolts and retainers while keeping the Brake Pad parts clean from lubrication. Adjust the brake caliper over the pads into its bracket before tightening the brake caliper pin bolts (1, 2) at 85 nm (63 ft. Lbs). Secure new copper brake gaskets onto the brake hose bolt assembly before attaching it to the caliper and tightening it to 45 nm pressure. Unlock the brake system pressure by pushing the brake pedal to two-thirds depth while the engine stays off then release it slowly. Apply the brake pedal for 15 seconds then stop while holding the pads and pistons in place for the right installation. Return the tire and wheel parts before bringing the vehicle back down.

Question 2

How to replace the rear brake calipers on Buick LaCrosse?

Accepted Answer

To replace the rear brake caliper one has to first check the fluid level in the brake master cylinder reservoir; if it is at or above the midway point between maximum-full and minimum allowable levels, discard fluid to the midway point. Lift and support the vehicle and also remove the tire and wheel assembly. Let off pressure from the park brake system at the equalizer and remove the front and rear cables at the connector clip. Remove the park brake cable from the park brake lever connected on the brake caliper as well as the caliper bracket. Detach brake hose to caliper bolt, and remove the brake hose from brake caliper then discard the 2 copper brake hose gaskets. Plug the holes in the brake caliper and brake hose to avoid losing and contaminating the fluid, then remove the brake caliper bolts and caliper. For installation line up the indentions on the piston face with the pin on the Brake Pad, and check bracket bolt guide assembly, and Brake Pad hardware and brake caliper on to the caliper bracket and make sure the guide boots are not damaged. Mount the brake caliper bolts and tighten them to 34 (Nm 25 lb ft). Unscrew the plugs at the end of the brake hose and install new copper brake hose gaskets after which assemble the brake hose bolt with the new gaskets onto the brake hose. Mount the brake hose to the caliper bolt to the brake caliper, with the hose held up as the nut is tightened to 54 n.m (40 lb ft). Mount the park brake cable onto the park brake bracket of the caliper and link it to the park brake lever. Bleed brake system: slowly press the pedal down to 2/3 travel distance, then release, repeat until a firm pedal should be gained and the engine is off. Modify the park brake system, re-install the tire and wheel assembly, and drive the vehicle down.

Question 3

How to replace the rear brake calipers bracket on Buick Regal?

Accepted Answer

To replace the rear Brake Caliper Bracket, first, remove the caliper from the mounting bracket and then secure it with heavy mechanics wire or some other tool while still having the hydraulic brake flexible hose attached. Second, uninstall the rear brake pads, then proceed to uninstall the caliper bracket bolts, before finally removing the caliper bracket. Iparameters prior to installation should be cleaned and visually inspected to ensure the proper clamp load using the threads of the caliper bracket bolts as well as the mounting holes of the knuckle. Threadlocker gm p/n 12345493 (Canadian P/N 10953488) or other should be applied to Brake Caliper Bracket bolt threads. Install the caliper bracket using bracket bolts and tighten them to 115 nm (85 ft. Lbs.). At last, put on the rear brake pads and the caliper.
