Solution

1. Preparation

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

2. Remove Wheel

Use a socket set to loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle with a jack and secure it on jack stands.
Remove the wheel completely to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the brake pads and suspend it using a bungee cord to avoid stress on the brake line.
Inspect the brake pads for wear; replace if below the manufacturer’s minimum thickness (typically 3-4 mm).
Install new brake pads, ensuring they are oriented correctly.

4. Inspect and Resurface/Replace Rotors

Check the rotors for signs of wear or damage. Measure rotor thickness with a micrometer.
If the rotors are within specifications, clean them with brake cleaner. If they are below minimum thickness or heavily scored, replace them.
If resurfacing, ensure it’s done according to manufacturer specifications.

5. Reassemble Brake Components

Carefully position the caliper back over the new pads.
Torque the caliper bolts to the manufacturer’s specifications (typically around 25-30 Nm).
Reattach the wheel and torque the lug nuts in a star pattern to the recommended torque (usually around 120 Nm).

6. Final Checks

Before lowering the vehicle, pump the brake pedal a few times to seat the pads against the rotors.
Lower the vehicle and perform a final inspection of the brake assembly.
