Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, jack and jack stands, dial indicator, brake cleaner, and new brake components (if needed).
Ensure the vehicle is on a level surface and turn off the ignition.

2. Lift the Vehicle

Use the jack to lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands to ensure stability.

3. Remove the Wheel

Using a socket set, loosen and remove the lug nuts.
Take off the wheel to access the braking components.

4. Inspect and Replace Brake Components

Inspect Rotors:
- Use a dial indicator to measure rotor runout. If warping is detected (more than 0.002 inches), replace the rotors.
Check Brake Pads:
- Inspect brake pads for thickness; replace them if they are worn down to less than 3mm.
Caliper Inspection:
- Ensure the caliper slides freely. If it is sticking, clean the caliper pins and lubricate them or replace the caliper if damaged.

5. Reassemble and Torque Components

Reinstall the brake components and ensure all bolts are tightened to manufacturer specifications.
Put the wheel back on and hand-tighten the lug nuts.

6. Lower the Vehicle and Perform Final Checks

Carefully lower the vehicle back to the ground.
Torque the lug nuts to the manufacturer’s specifications.
Check brake fluid levels and top off if necessary.
