Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Remove Wheel

Loosen the lug nuts on the affected wheel.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads:
- Remove the caliper bolts and slide the caliper off the rotor.
- Inspect the brake pads for wear; replace if the thickness is below 3mm.
- Install new brake pads, ensuring they are properly seated in the caliper bracket.
Brake Rotors:
- Check the rotor for warping using a dial indicator or visual inspection.
- If warped, remove the rotor by unbolting it from the hub.
- Install a new brake rotor, ensuring it is torqued to the manufacturer's specifications (usually around 80-100 ft-lbs).

4. Check Suspension Components

Inspect control arms, bushings, and ball joints for damage or excessive play.
Replace any worn components as necessary to ensure proper suspension alignment and function.

5. Reassemble and Torque

Reattach the caliper over the new brake pads and rotor, tightening the caliper bolts to the recommended torque.
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually around 100-120 ft-lbs).
