Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety goggles and gloves.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Use a run-out gauge to measure rotor warpage; a variance greater than 0.002 inches indicates replacement.
Replace Rotors (if necessary):
1. Unbolt the caliper from the bracket and suspend it using a bungee cord.
2. Remove the rotor by unbolting it from the hub.
3. Clean the hub surface with brake cleaner.
4. Install the new rotor and torque the bolts to the manufacturer specification (usually around 70-90 lb-ft).

4. Inspect and Replace Brake Pads

Inspect Pads:
- Check for uneven wear or contamination on the pads.
Replace Pads (if necessary):
1. Remove the caliper bracket bolts to free the caliper.
2. Replace the pads, ensuring they are properly seated.
3. Reinstall the caliper and torque the bolts to specification (typically around 20-30 lb-ft).

5. Inspect Suspension Components

Check control arms, ball joints, and bushings for play.
Replace any worn or damaged components as needed.
