Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to prevent electrical issues during repairs.

2. Inspect and Replace Brake Components

Remove the Wheel
- Use a socket set to loosen and remove lug nuts.
- Lift the vehicle using a jack and secure it with jack stands.
Inspect Brake Pads
- Remove the caliper bolts with a socket wrench.
- Slide the caliper off the rotor and support it with a bungee cord (do not disconnect the brake line).
- Inspect the brake pads for wear; if they are below the manufacturer's specifications, replace them.
Check Brake Rotors
- Measure rotor thickness with a micrometer; if the rotor is warped (more than 0.002 inches) or below the minimum thickness, replace it.
- If rotors are in good condition, clean them with brake cleaner and a wire brush.
Reassemble Braking System
- Reinstall the caliper and torque bolts to manufacturer specifications.
- Replace the wheel and torque lug nuts to the specified setting.

3. Inspect Suspension Components

Check for Wear
- Visually inspect control arms, tie rods, and bushings for signs of wear or damage.
- Replace any worn suspension parts as necessary.

4. Wheel Alignment and Balancing

Align and Balance
- Take the vehicle to a professional for a wheel alignment and balancing, especially if any suspension components were replaced.
