Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is on a flat surface and engaged in park mode.
Use wheel chocks to prevent movement.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle as needed.
Secure with jack stands to ensure safety.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Compare the thickness of the inner and outer pads.
Remove Caliper:
- Use a socket to unbolt the caliper from the bracket.
- Carefully slide the caliper off the rotor without stretching the brake line.
Remove Old Pads:
- Slide the old brake pads out of their slots.
Install New Pads:
- Apply brake grease to the backing of the new pads (if applicable) to reduce noise.
- Install the new pads in place of the old ones.

5. Check and Replace Rotors (if necessary)

Remove Brake Rotor:
- If the rotor is warped or scored, unbolt it from the hub.
Install New Rotor:
- Clean the new rotor with brake cleaner and install it in the reverse order of removal.

6. Reassemble and Lower Vehicle

Reattach the caliper over the new pads and torque bolts to the manufacturer’s specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value.
