Solution

1. Preparation

Gather tools and parts necessary for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the braking system.

2. Remove Wheel

Use a jack to lift the front or rear of the vehicle depending on where the issue is.
Secure the vehicle with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Measure the rotor thickness with a micrometer. If below minimum specification or warped, replace.
Replace Rotors (if necessary):
- Remove caliper bolts and slide the caliper off the rotor.
- Remove the old rotor and install a new rotor, ensuring it is properly seated.
- Reinstall the caliper and torque bolts to manufacturer specifications (usually around 70-90 ft-lbs).
Inspect Brake Pads:
- Check the thickness of the brake pads. If they are worn down, replace them.
Replace Brake Pads (if necessary):
- Remove the caliper bracket bolts and take out the old pads.
- Install new pads and ensure proper alignment.
- Reassemble the caliper and torque bolts to manufacturer specifications.

4. Inspect and Repair Suspension Components

Inspect control arms, tie rods, and other suspension parts for damage or wear.
Replace any worn or damaged components using appropriate tools.

5. Reassemble and Test

Reinstall the wheel and torque the lug nuts to manufacturer specifications (usually 76-80 ft-lbs).
Reconnect the battery.
Lower the vehicle and perform a test drive to ensure the issue is resolved.
