Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Lift the Vehicle

Use a hydraulic jack to raise the front or rear of the vehicle as needed.
Secure the vehicle on jack stands for safety.

3. Remove Wheel

Use a lug wrench to remove the wheel bolts and take off the wheel.
Ensure to keep lug bolts in a safe place.

4. Inspect Brake Pads and Rotors

Remove the caliper by unbolting it from the bracket; use a socket set.
Carefully hang the caliper using a bungee cord to avoid stress on the brake line.
Inspect the brake pads for uneven wear; replace if worn down below the minimum thickness.
Use a runout gauge to measure rotor warping; replace rotors if they exceed manufacturer specifications.

5. Replace Brake Pads and Rotors (if necessary)

If pads or rotors are worn, install new components:
- Brake Pads: Apply brake grease on the backing of the pads. Install new pads into the caliper bracket.
- Rotors: Remove the old rotor and install the new rotor, ensuring it is seated properly.
Torque the caliper bolts to the manufacturer’s specifications (typically around 25-35 Nm).

6. Reassemble and Test

Reinstall the caliper over the new pads and rotor.
Reattach the wheel and hand-tighten the lug bolts.
Lower the vehicle and torque the lug bolts to the specified torque (typically around 100 Nm).
