Solution

1. Preparation

Gather necessary tools and parts for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if required for any electrical components.

2. Brake Pad and Rotor Replacement

Tools Required:
- Jack and jack stands
- Lug wrench
- C-clamp or brake caliper tool
- Torque wrench
- Dial indicator (for rotor measurement)
Sub-steps:
1. Loosen the lug nuts on the front wheels before lifting the vehicle.
2. Use the jack to lift the vehicle and secure it with jack stands.
3. Remove the wheel using the lug wrench.
4. Remove the brake caliper by unbolting it from the bracket; support it with a wire to avoid strain on the brake line.
5. Remove the old brake pads from the caliper bracket.
6. Use the C-clamp or brake caliper tool to compress the caliper piston back into the caliper housing.
7. With the brake pads removed, check the rotor for warping using a dial indicator; if warped, replace the rotor.
8. Install new brake pads into the caliper bracket, ensuring they are seated properly.
9. Reattach the brake caliper and torque the bolts to the manufacturer's specifications (typically around 20-30 ft-lbs).
10. Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

3. Suspension Component Inspection and Replacement

Tools Required:
- Socket set
- Torque wrench
- Pry bar (if needed)
Sub-steps:
1. Inspect the tie rods, ball joints, and control arms for any signs of wear or damage.
2. If any components are worn, replace them using the socket set; ensure proper alignment when reinstalling.
3. Torque all bolts to the manufacturer’s specifications.
