Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel Assembly

Use a jack to lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands.
Remove the wheel using a socket set.

3. Inspect and Replace Brake Pads

Inspect Pads:
- Remove the brake caliper by unscrewing the caliper bolts with a socket set.
- Slide the caliper off the rotor and support it with a bungee cord to avoid stress on the brake line.
- Check the brake pads for thickness; replace them if they are worn down to 3mm or less.
Replace Pads:
- If replacement is needed, remove the old pads from the caliper bracket.
- Apply brake grease on the back of the new pads to prevent squeaking.
- Install the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for scoring and warping by running your finger across the rotor surface.
Replace Rotors:
- If the rotors are damaged, remove them by unscrewing the rotor retaining screws (if present) and pulling the rotor off the hub.
- Install new rotors and torque to the manufacturer’s specifications (usually around 85-100 ft-lbs, but check the manual).

5. Reassemble Braking System

Reinstall the brake caliper over the new pads and rotor.
Torque the caliper bolts to the manufacturer’s specifications.
Reinstall the wheel and torque the lug nuts in a crisscross pattern to the proper torque specification (typically 80-100 ft-lbs).

6. Final Checks

Reconnect the battery.
Pump the brake pedal to ensure proper seating of the brake pads.
Double-check for any tools left in the wheel well.
