Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks for additional safety.

2. Remove Wheels

Tools Required: Lug wrench, jack, jack stands.
Loosen the lug nuts on the front wheels.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the front wheels.

3. Inspect Brake Components

Check the brake rotors:
- Remove the brake caliper by unbolting it from its mounting bracket.
- Inspect the surface of the rotor for warping; if warped beyond specification (typically over 0.002 inches), replace the rotor.
Check the brake pads:
- Measure the thickness of the pads; if less than 3mm, replace them.
- Look for signs of uneven wear or glazing.
Inspect calipers:
- Ensure calipers move freely on their slides and are not sticking. If they are, clean and lubricate or replace as necessary.

4. Replace or Machine Rotors

If rotors are warped:
- If within specifications, machine the rotors; if not, replace with new ones.
Ensure proper torque when reinstalling rotor bolts (typically 70-85 ft-lbs).

5. Reassemble Braking System

Reinstall calipers and ensure all bolts are torqued to specifications.
Replace wheels and hand-tighten lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value (typically 76-80 ft-lbs).

6. Test Drive

After reassembly, conduct a test drive to ensure proper braking function and check for any vibrations.
