  Q: How to replace the front brake pads on Buick Rainier?

  A:

  Before working on the front brake pads check the brake fluid level in the master cylinder reservoir. No fluid needs to be adjusted if the mark sits between full and lowest safe marks but if the level is above that range use a brake fluid extractor tool to relocate it to the midway point. Lift the vehicle and take off its tire and wheel components. Push the piston into the brake caliper using a large c-clamp on top of the brake housing over the piston. Slowly tighten the clamp until the piston reaches brake caliper depth and then remove the clamp. Take out the lower guide pin bolt now to move the brake caliper up to its stopping point while you extract the Brake Pad sets plus mounting clips from the Brake Caliper Bracket and housing. Use a clean alcohol solution to eliminate all foreign pieces from the brake caliper. You need to replace Brake Pad retaining clips whenever you put new brake pads on the car. Install one clip on each side into the brake caliper mounting bracket and brake caliper. Order the brake caliper clip to perfectly fit inside. Fit both brake pads in their spaces then push the brake caliper down to its place while screwing the lower guide pin bolt to 42 nm (31 ft.lbs.). Place the tire wheel back in place then secure it while lowering the vehicle before refilling the master cylinder reservoir. Use slow and strong Brake Pedal pressure to place the brake pads correctly and create a smooth surface on new brake pads.

  Q: How to replace the rear brake pads on Buick Rainier?

  A:

  Before starting Brake Pad replacement check the brake fluid level in the master cylinder reservoir. If the fluid exceeds the halfway mark between maximum and minimum limits then use a fluid extractor to bring the level to midway. Lift the vehicle and then extract both the tire and wheel unit. Apply the large c-clamp on top of brake caliper housing to press the Brake Caliper Piston while screwing the bolt until the piston moves backward enough to release the caliper from the rotor. After disconnecting the upper brake caliper bolt and rotating the rear brake caliper down you should take out the brake pads and pad retaining clips from both the brake caliper and mounting bracket, plus the retaining clip from the brake caliper. Wipe the brake caliper mounting bracket with denatured alcohol and let it air dry through non-lubricated filtered air. To install new brake pads you should use fresh Brake Pad retaining clips first. Locate the clips on the brake caliper mounting bracket then put on brake pads. Make sure the retaining clip for the brake pads fits correctly into the caliper housing. Put the brake caliper retaining clip back in while guiding the rear brake caliper up to its place and screwing the upper brake caliper bolt tight at 31 nm. Place the tire and wheel back in position while lowering the vehicle body then top up the brake master cylinder when needed. Push the Brake Pedal down gradually yet with force to make brake pads settle and let the friction material smooth against the rotors.
