Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Raise the Vehicle

Use a jack to lift the rear of the vehicle.
Secure with jack stands to prevent accidental lowering.
Remove the rear wheels using a socket set.

3. Inspect and Remove Brake Components

Inspect Brake Pads:
- Remove the brake caliper by loosening caliper bolts (torque specifications: usually around 25-35 ft-lbs).
- Slide the caliper off and support it using a bungee cord or similar.
- Check the thickness of the brake pads; if they are below 3mm, they must be replaced.
Inspect Brake Rotors:
- Check the surface of the rotors for deep grooves or warping.
- If damaged, remove the rotors by unscrewing the rotor retaining screws (if applicable) and sliding them off the hub.

4. Install New Components

Replace Brake Pads:
- Install new brake pads, ensuring they are oriented correctly.
- Apply anti-squeal lubricant to the back of the pads (if required).
Replace Rotors (if needed):
- If rotors were damaged, install new ones by sliding them onto the hub.
- Secure with retaining screws and tighten to manufacturer specifications.

5. Reassemble and Test

Reattach the brake caliper and torque the bolts to specifications.
Replace the wheels and lower the vehicle from the jack stands.
Pump the brake pedal several times to seat the pads against the rotors.
