Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is on a flat surface and secure with wheel chocks.
Disconnect the battery for safety.

2. Inspect and Remove Wheels

Tools Required: Jack, jack stands, lug wrench.
Lift the vehicle using the jack and support it with jack stands.
Remove the wheels to access the brake components.

3. Inspect Brake Rotors

Tools Required: Caliper tool, micrometer.
Check the rotors for warping using a micrometer; they should not exceed manufacturer specifications.
If warped, remove the caliper bolts and slide the caliper off the rotor.

4. Replace or Resurface Rotors

If rotors are warped, either resurface them or replace them.
Sub-steps:
- For resurfacing, mount the rotors on a lathe according to the manufacturer's guidelines.
- If replacing, install new rotors and torque to manufacturer specifications (typically around 60-80 ft-lbs).

5. Inspect and Replace Brake Pads

Inspect the brake pads for wear; replace if they are worn down to the minimum thickness.
Sub-steps:
- Remove old pads from the caliper bracket.
- Install new pads, ensuring they are properly seated.
- Apply brake lubricant to the backing of the pads to prevent noise.

6. Check Suspension Components

Inspect suspension components for wear. Replace any damaged parts such as bushings or control arms.
Tools Required: Socket set, torque wrench.
Ensure that all nuts and bolts are torqued to specifications.

7. Reassemble and Reinstall Wheels

Reinstall the wheels and torque lug nuts to manufacturer specifications.
Remove the jack stands and lower the vehicle.
