2
Check the condition of the brake rotors for warping or scoring.
3
Examine brake calipers for proper function and signs of sticking.
4
Measure rotor thickness using a micrometer to ensure they meet specifications.

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake caliper tool, micrometer, torque wrench.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Raise the Vehicle

Use the jack to lift the front or rear of the vehicle depending on which brakes are affected.
Secure the vehicle with jack stands.
Remove the wheel using the lug wrench.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the brake caliper bolts with the appropriate socket.
- Carefully slide the caliper off the rotor, supporting it to avoid stress on the brake line.
- Inspect the brake pads for thickness; replace if worn beyond the manufacturer's specifications.
- Clean the caliper and the bracket with brake cleaner.
- Lubricate the caliper slide pins and install new brake pads.

4. Check and Resurface/Replace Brake Rotors

Sub-steps:
- Remove the brake rotor from the hub by unscrewing the retaining screws (if applicable).
- Measure the rotor thickness with a micrometer. If the rotor is within tolerance but warped, consider resurfacing.
- If the rotor is below minimum thickness, replace it with a new one.
- Install the rotor back onto the hub and secure it.

5. Reassemble and Torque

Reinstall the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's specified torque using a torque wrench.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle

Remove jack stands and lower the vehicle back to the ground.
Tighten the lug nuts to the specified torque in a star pattern.
