Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the negative terminal of the battery for safety.

2. Inspect and Replace Brake Components

Remove Wheel:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts with a socket and ratchet, then take off the wheel.
Inspect Brake Rotors:
- Check the surface of the rotors for grooves or warping.
- Use a dial indicator to measure rotor run-out; if it exceeds manufacturer specifications, replace the rotor.
Replace Brake Pads:
- Remove the caliper by loosening the caliper bolts; support it with a bungee cord to avoid strain on the brake line.
- Remove the old brake pads and inspect the caliper for any damage or sticking.
- Install new brake pads, ensuring they are properly seated.
Reinstall Caliper and Wheel:
- Reattach the caliper and torque the bolts to the manufacturer’s specifications.
- Reinstall the wheel and hand-tighten the lug nuts.

3. Check Wheel Alignment and Suspension Components

Inspect Suspension:
- Check all suspension components (control arms, bushings, ball joints) for wear or damage.
- Replace any worn components.
Perform Wheel Alignment:
- Take the vehicle to a professional alignment shop to ensure proper alignment is restored.
