Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the brakes.

2. Remove Wheel

Use a jack to lift the vehicle and place jack stands for support.
Remove the lug nuts with a socket wrench and take off the wheel to access the brake components.

3. Inspect Brake Components

Check the brake pads:
- If they are worn down below the manufacturer's specified thickness, replace them.
Inspect the brake rotors:
- Measure rotor thickness with a micrometer; if below specification, replace or resurface.
- Examine for grooves or scoring; replace if necessary.

4. Replace Brake Pads and Rotors (if needed)

Remove caliper bolts and carefully take off the caliper.
Slide out the old brake pads from their brackets.
If replacing rotors, remove the rotor from the hub by removing the retaining screws.
Install new rotors if applicable, securing with screws.
Insert new brake pads into the caliper bracket.
Reinstall the caliper over the new pads, tightening bolts to manufacturer’s torque specifications (typically 20-30 ft-lbs).

5. Reassemble and Test

Reinstall the wheel and lug nuts, tightening in a crisscross pattern.
Lower the vehicle and reconnect the battery.
Pump the brake pedal a few times to ensure proper pad seating and brake operation.
