Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels for added safety.

2. Remove Wheel

Use a socket set to loosen the lug nuts slightly while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

A. Inspect Brake Rotors

Check the rotor surface for warping or scoring.
If warped, use a rotor lathe to resurface or replace the rotor.

B. Inspect Brake Pads

Remove the caliper by unscrewing the caliper bolts with a socket set.
Slide the caliper off and support it with a bungee cord (do not let it hang by the brake line).
Inspect the brake pads for thickness; replace if worn below manufacturer's specifications.

4. Reassemble Components

If any components were replaced, install new brake pads and rotor in the reverse order.
Tighten caliper bolts to the manufacturer's torque specifications (typically around 25-30 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Final Tightening

Carefully lower the vehicle back to the ground.
Use the torque wrench to tighten the lug nuts to the manufacturer's specification (usually around 75-80 lb-ft).
