Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Raise Vehicle

Use a jack to lift the front or rear (depending on which brakes need inspection).
Secure the vehicle with jack stands.

3. Remove Wheel

Use a lug wrench to remove the lug nuts and take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness; if less than 1/8 inch, replace them.
Remove Old Brake Pads:
- Remove caliper bolts with a socket set.
- Carefully slide the caliper off the rotor.
- Remove the old brake pads from the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the back of the new pads to reduce noise.
- Install the new pads into the caliper bracket.

5. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for grooves or warping.
Remove Rotors:
- If replacement is necessary, remove caliper bracket bolts and detach the bracket.
- Remove the rotor from the hub.
Install New Rotors:
- Place the new rotor onto the hub and secure it.

6. Reassemble Components

Reinstall Caliper:
- Position the caliper over the new pads and rotor.
- Tighten caliper bolts to manufacturer’s torque specifications (usually around 25-35 ft-lbs).
Reattach Wheel:
- Place the wheel back onto the hub and hand-tighten lug nuts.
- Lower the vehicle and then torque the lug nuts to 80-100 ft-lbs.
