Solution

1. Preparation

Gather tools and parts required for the brake inspection and repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Visually inspect brake pads for thickness; replace if worn down to 3mm or less.
Check the brake rotors for any scoring or warping; resurface or replace if necessary.
Inspect the calipers for signs of corrosion or damage; replace if necessary.

4. Replace Brake Pads and/or Rotors (if needed)

Brake Pads Replacement:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and support it without stretching the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads ensuring they are seated properly.
- Use a brake caliper tool to compress the caliper piston back into its bore.
Rotor Replacement:
- If replacing rotors, remove the rotor by unscrewing any retaining screws and sliding it off the hub.
- Clean the hub surface with a wire brush to ensure proper contact with the new rotor.
- Install the new rotor, securing it with retaining screws.

5. Reassemble and Test

Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications.
Put the wheel back on, hand-tighten the lug nuts, lower the vehicle, and then torque the lug nuts to the proper specification.
Pump the brake pedal a few times to ensure proper pad seating and caliper function.
