Solution

1. Preparation

Gather the necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and place wheel chocks in front of the front wheels.
Disconnect the negative battery terminal to ensure safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the rear wheel.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads. Replace if below manufacturer specifications (usually 3mm or less).
Remove Old Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor. Support it with a bungee cord or hang it to avoid strain on the brake line.
Install New Brake Pads:
- Apply brake grease to the backing of the new pads (avoid the friction surface).
- Slide the new pads into place and reattach the caliper.
Torque Specifications:
- Tighten caliper bolts to the manufacturer’s torque specifications (usually around 25-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Measure rotor thickness and look for signs of wear. Replace if warped or below minimum thickness.
Remove Rotor:
- If replacing, remove the caliper bracket if necessary, and unscrew the rotor retaining screws.
- Slide off the old rotor.
Install New Rotor:
- Place the new rotor onto the hub and secure it with screws.

5. Reassemble and Refill Brake Fluid

Reattach the wheel, hand tighten the lug nuts, and lower the vehicle.
Refill the brake fluid reservoir with the appropriate type of brake fluid (DOT 3 or DOT 4 depending on specifications).
Reconnect the negative battery terminal.
