Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Gather safety equipment: gloves, safety glasses.

2. Inspect Brake Components

Tools Required: Jack and jack stands, wheel chocks, lug wrench.
Instructions:
1. Loosen the lug nuts slightly before raising the vehicle.
2. Use the jack to lift the vehicle and secure it with jack stands.
3. Remove the wheel to access the brake components.
4. Visually inspect the brake pads for uneven wear or thickness.
5. Measure the thickness of the rotors using a micrometer; replace if below manufacturer specifications.

3. Replace Brake Pads and Rotors (if needed)

Tools Required: Brake pad spreader, torque wrench, socket set.
Instructions:
1. Remove the caliper bolts using the appropriate socket.
2. Carefully lift the caliper off the rotor and support it (do not let it hang by the brake line).
3. Remove old brake pads from the caliper bracket.
4. Install new brake pads, ensuring they are properly aligned.
5. Replace the rotor if warped by removing the rotor retaining screws.
6. Install the new rotor and secure it with screws.
7. Reinstall the caliper and tighten bolts to manufacturer specifications using a torque wrench.

4. Inspect and Repair Suspension Components

Tools Required: Wrench set, pry bar.
Instructions:
1. Inspect control arms, bushings, and tie rods for wear or damage.
2. Replace any worn components, ensuring proper alignment when reassembling.

5. Tire Balance and Alignment

Tools Required: Tire balancer, alignment tools (if applicable).
Instructions:
1. Remove the wheels and have them balanced at a tire shop.
2. Check and adjust the wheel alignment according to manufacturer specifications.
