Solution

1. Preparation

Gather necessary tools and parts.
Elevate the rear of the vehicle using a jack and secure with jack stands.
Remove the rear wheels using a socket set.

2. Remove Brake Components

Remove the Caliper:
- Locate and remove the caliper mounting bolts using a socket.
- Carefully slide the caliper off the rotor and support it using a bungee cord or rope to avoid straining the brake line.
Remove the Brake Pads:
- Slide out the old brake pads from the caliper bracket.
- Inspect the anti-rattle clips and shims; replace if damaged.

3. Inspect and Clean

Inspect the Rotor:
- Check the rotor for any signs of damage or excessive wear. If warped or below the minimum thickness, replacement is necessary.
- Clean the rotor surface using brake cleaner and a clean rag to remove dust and debris.
Clean Caliper and Components:
- Use a wire brush to clean any rust or debris from the caliper and mount.

4. Install New Brake Pads

Install New Brake Pads:
- Apply brake grease to the back of the new pads and any contact points with the caliper bracket.
- Insert new pads into the caliper bracket, ensuring they are secured properly.

5. Reassemble Brake Components

Reinstall the Caliper:
- Compress the brake caliper piston using a C-clamp to allow clearance for the new pads.
- Carefully slide the caliper back over the new pads and secure it with the mounting bolts. Torque bolts to manufacturer specifications (typically around 25-30 ft-lbs).

6. Final Checks

Reinstall the wheel and lower the vehicle.
Pump the brake pedal to seat the pads against the rotor.
Check brake fluid level and top up if necessary.
