Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and set the parking brake.
Wear safety gloves and goggles.

2. Raise the Vehicle

Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a socket set.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper by loosening the caliper bolts (typically 13mm or 15mm).
- Inspect the brake pads for uneven wear; replace if thickness is below 3mm.
Brake Rotors:
- Inspect rotors for warping or scoring. Use a dial indicator to check for runout.
- If warped, either machine the rotors or replace them with new ones.

4. Replace Brake Pads and Rotors (if necessary)

Replacing Pads:
- Remove old pads and install new pads ensuring they are seated properly in the caliper bracket.
Replacing Rotors:
- If replacing, remove the rotor by unscrewing the retaining screws if present and slide off.
- Install new rotor, ensuring it is secured properly.

5. Reassemble Components

Reattach the caliper and torque the caliper bolts to manufacturer specifications (usually around 20-30 ft-lbs).
Reinstall the wheels and torque lug nuts to the specified value (typically 100-150 ft-lbs).

6. Lower the Vehicle

Remove jack stands and lower the vehicle to the ground.
Pump the brake pedal a few times to seat the brake pads.
