One, take your brake fluid reservoir cap off.
Two, use a thin piece of wood to help you compress the piston on the caliper....do it slow. This way, you don't create a lot of pressure to the reservoir and it won't overflow.
Three, these are the steps to removing and replacing the pads for the rear. It does mention a special tool....but you can use a c-clamp for the same purpose:
- Check the brake fluid level in the brake master cylinder reservoir.
- If required, remove the fluid until the brake master cylinder reservoir is half full.
Care must be taken when servicing rear brake components without disconnecting the parking brake cable from the brake caliper lever.
- Remove the disc brake caliper. Support the caliper with mechanic's wire.
When the brake pads are separated from the brake caliper, new brake pads must be installed. The brake pads are one-time use only.
- Remove and discard the brake pads and spring clips from the brake caliper anchor plate.
NOTE: Do not remove the anchor plate guide pins. The guide pins are press fit to the brake caliper anchor plate. If the guide pins are damaged a new anchor plate must be installed.
- Inspect the brake caliper anchor plate assembly.
- Check the guide pins and boots for binding or damage.
- Install a new brake caliper anchor plate if it is worn or damaged.
The left caliper piston turns clockwise and the right caliper piston turns counterclockwise.
- Using the special tool, turn and compress the brake caliper piston into the cylinder.
- Clean the residual adhesive from the brake caliper fingers and pistons using the specified brake parts cleaner.
Do not allow grease, oil, brake fluid or other contaminants to contact the brake pad or caliper mating surface. Do not install contaminated pads.
NOTE: Install all the new hardware supplied with brake pad kit.
- Install the new spring clips and brake pads.
- Position the brake caliper and install the 2 bolts. Tighten caliper bolts to 23 ft-lbs (31 Nm).
- If necessary, fill the brake master cylinder reservoir with clean brake fluid.
- With the engine running, apply pressure on the brake pedal to seat the brake pads.
- Test the brakes for normal operation.
