Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Use wheel chocks to prevent rolling.
Disconnect the battery negative terminal for safety.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Lift the vehicle with a jack and secure it with jack stands.
Remove the wheel to access the braking components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Look for wear indicators; if they are close to the rotor, replace the pads.
Remove Brake Caliper:
- Use a socket set to remove caliper mounting bolts.
- Carefully slide the caliper off the rotor and support it using a bungee cord or wire to avoid strain on the brake line.
Replace Brake Pads:
- Remove old pads from the caliper bracket.
- Install new pads, ensuring they align correctly with the caliper.

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotor Condition:
- Use a caliper gauge to measure rotor thickness; if below specifications or scored, replace the rotor.
Remove Rotor:
- Remove any retaining screws, if applicable.
- Slide the rotor off the hub.
Install New Rotor:
- Clean the new rotor with brake cleaner to remove any protective coating.
- Install the new rotor onto the hub securely.

5. Reassemble Braking Components

Reinstall the brake caliper over the new pads and rotor.
Torque caliper mounting bolts to manufacturer specifications (generally around 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle and remove jack stands.
Tighten lug nuts in a star pattern to the specified torque (typically 80-100 ft-lbs).
Reconnect the battery terminal.
