Solution

1. Preparation

Gather tools and parts required for repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Tire and Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Rotors:
- Check for warping using a dial indicator. If warped, replace the rotors.
Replace Brake Pads:
- Remove caliper bolts using a socket wrench.
- Lift the caliper off the rotor and support it with a wire hanger.
- Remove old brake pads and install new ones ensuring they are properly aligned.

4. Reassemble Components

Reinstall the caliper and torque bolts to manufacturer specifications (typically 25-35 ft-lbs).
Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and torque lug nuts to specification (usually 80-100 ft-lbs).

5. Test Drive

Conduct a test drive to ensure proper brake function and check for vibrations.
