Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, wire brush, and safety glasses.
Raise the rear of the vehicle using the jack and secure it with jack stands. Remove the rear wheels using the lug wrench.

2. Remove Brake Components

Sub-steps:
1. Remove the caliper mounting bolts using a socket wrench.
2. Carefully slide the caliper off the brake rotor. Support it with a bungee cord or wire to avoid straining the brake line.
3. Remove the old brake pads from the caliper bracket.

3. Inspect and Clean

Sub-steps:
1. Check the brake rotor for scoring or excessive wear. Replace if necessary.
2. Clean the rotor surface with brake cleaner and a wire brush.
3. Inspect the caliper for leaks and proper movement. Replace if damaged.

4. Install New Brake Pads

Sub-steps:
1. Apply brake grease to the back of the new brake pads.
2. Install the new brake pads into the caliper bracket.
3. Reposition the caliper over the new pads and align it with the rotor.

5. Reassemble and Bleed Brakes

Sub-steps:
1. Tighten the caliper mounting bolts to the manufacturer's specified torque (usually around 20-25 ft-lbs).
2. Reinstall the wheels and lower the vehicle.
3. Pump the brake pedal several times to seat the pads and ensure proper brake function. Check brake fluid level and bleed if necessary.
