Inspect brake pads and rotors for wear and damage.
2
Check brake rotor thickness with a micrometer to ensure they are within manufacturer specifications.
3
Examine wheel bearings for play or damage.
4
Inspect suspension components for wear or looseness.

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle.
Secure with jack stands to ensure stability.

3. Remove Front Wheels

Use a lug wrench to loosen and remove the lug nuts.
Carefully take off the front wheels.

4. Inspect and Replace Brake Components

Brake Pads:
- Remove caliper bolts with a socket wrench.
- Slide the caliper off the rotor.
- Remove old brake pads and replace them with new ones.
Brake Rotors:
- If warped, remove the rotor by unscrewing the retaining screws (if applicable).
- Install the new rotor, ensuring it is seated properly.

5. Reassemble Braking System

Reinstall the caliper over the new pads and tighten the caliper bolts to manufacturer specifications (typically 20-25 ft-lbs).
Reinstall the wheels and hand-tighten the lug nuts.

6. Lower the Vehicle

Carefully lower the vehicle back to the ground.
Tighten the lug nuts to the specified torque (usually 75-85 ft-lbs) in a crisscross pattern.
