Solution

1. Preparation

Tools Required: Jack, jack stands, tire iron, torque wrench, runout gauge, caliper gauge.
Raise the vehicle using a jack and support it securely with jack stands.
Remove the front or rear wheels, depending on where the problem is suspected.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the caliper by unbolting it from the bracket and securing it to avoid strain on the brake line.
2. Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
3. Use a runout gauge to measure rotor warpage. Replace if warping exceeds manufacturer specifications (typically 0.002 inches).
4. Install the new rotor by aligning it with the hub and securing any retaining screws.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bracket by unbolting it from the steering knuckle.
2. Remove old brake pads from the caliper bracket.
3. Measure the thickness of the new pads to ensure they meet specifications.
4. Install new brake pads into the caliper bracket and reattach the bracket to the vehicle.

4. Inspect Suspension Components

Sub-steps:
1. Check control arms, ball joints, and tie rod ends for any signs of wear or damage.
2. Replace any worn components with OEM or high-quality aftermarket parts.

5. Wheel Alignment and Balancing

Sub-steps:
1. After reassembling the braking system, mount the wheels back onto the vehicle.
2. Check tire pressure and adjust to manufacturer specifications.
3. Take the vehicle to a professional shop for a wheel alignment and balancing.
