Solution

1. Preparation

Gather tools and parts required for the repair.
Safely raise the vehicle using a jack and secure it with jack stands.
Remove the wheels for access to the brakes and suspension components.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and support it to avoid straining the brake line.
3. Remove old brake pads from the caliper bracket.
4. Install new brake pads, ensuring they are positioned correctly.
5. Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specification (typically around 20-25 ft-lbs).

3. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the brake rotor by unscrewing the retaining screws (if applicable) and pulling it off the hub.
2. Measure rotor thickness and inspect for warping with a micrometer.
3. If warped or below minimum thickness, replace with new rotors.
4. Install new rotors and secure with retaining screws.
5. Apply anti-seize lubricant to the hub surface to prevent future seizing.

4. Check and Replace Suspension Components

Sub-steps:
1. Inspect tie rods for play or damage; replace if necessary.
2. Examine control arms and bushings for wear; replace if degraded.
3. Tighten any loose bolts to manufacturer specifications.

5. Wheel Alignment and Balancing

Sub-steps:
1. After reassembly, take the vehicle to a professional alignment shop.
2. Ensure all angles (camber, caster, toe) are set to manufacturer specifications.
3. Balance the wheels to eliminate any vibration.
