Solution

1. Preparation

Gather tools and parts needed.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Remove Wheel

Use a lug wrench to loosen wheel lug nuts (do not fully remove yet).
Raise the vehicle using a jack and secure with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Visually inspect brake pads for thickness; replace if below 3mm.
Check brake rotors for scoring or warping. If warped, proceed to replace.
Measure rotor thickness using a micrometer; replace if below minimum specifications.

4. Replace Brake Pads and Rotors (if necessary)

Remove caliper bolts using a socket set, and carefully slide caliper off the rotor.
If pads are worn, remove them from the caliper bracket.
Install new brake pads into the caliper bracket.
For rotor replacement, remove the old rotor and install the new rotor, ensuring it is properly seated.

5. Reassemble Components

Reattach the caliper over the new rotor and secure with caliper bolts to manufacturer’s torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten lug nuts to the specified torque.

6. Test Drive

Start the vehicle and perform a test drive to ensure braking performance is restored and no vibrations are present.
