Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Use wheel chocks to secure the vehicle.

2. Lift the Vehicle

Use a jack to raise the front or rear of the vehicle, depending on which brakes are affected.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper by unscrewing the caliper bolts using a socket wrench.
- Check the brake pads for thickness; replace if worn below 3mm.
Replacement:
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly seated.
- Apply brake grease to the back of the pads to reduce noise.

5. Inspect and Resurface or Replace Brake Rotors

Check rotors for any grooves or scoring. If damaged, either resurface or replace them.
To replace rotors, remove the caliper bracket and unscrew the rotor retaining screws, if applicable.
Install new or resurfaced rotors, ensuring they are clean and free of rust.

6. Reassemble Components

Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer specifications.
Reattach the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle and Finalize

Carefully remove the jack stands and lower the vehicle with the jack.
Tighten the lug nuts to the specified torque in a crisscross pattern.
