Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Remove Wheel

Loosen lug nuts with a lug wrench.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and support it with a wire to avoid strain on the brake line.
- Inspect the brake pads for thickness; replace if they are less than 3mm.
Brake Rotors:
- Check the rotors for any visible grooves, cracks, or scoring.
- If necessary, measure rotor thickness with a caliper; replace if below manufacturer specifications.

4. Replace Brake Pads and Rotors (if necessary)

Brake Pads:
- Remove old brake pads from the caliper bracket.
- Apply brake grease to the back of the new pads to prevent noise and install them.
Brake Rotors:
- If replacing, remove the old rotor by unscrewing any retaining screws if present.
- Install the new rotor, ensuring it is seated properly.

5. Reassemble Braking System

Reattach the caliper over the new pads and rotor.
Replace caliper bolts and torque to the manufacturer’s specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).

6. Final Check

Pump the brake pedal a few times to seat the pads against the rotor.
Inspect brake fluid levels and top off if necessary.
