Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly before lifting the vehicle.
Lift the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Brake Pads: Remove the caliper by unbolting it from the bracket. Check for uneven wear. Replace if necessary.
Brake Rotors: Measure rotor thickness with a micrometer. If warping is detected (more than 0.002 inches), replace the rotors.
Calipers: Inspect for any signs of sticking or damage. Replace if necessary.

4. Reassemble and Replace Components

Install new brake pads and rotors if applicable. Ensure to torque bolts to the manufacturer’s specifications (typically 20-30 ft-lbs for caliper bolts).
Reattach the caliper and ensure it moves freely.
Reinstall the wheel and torque lug nuts to the specified value (generally 80-100 ft-lbs).

5. Final Checks

Lower the vehicle from the jack stands.
Pump the brake pedal several times to seat the pads.
Perform a visual inspection of all components to ensure proper installation.
