Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Use a caliper tool to retract the brake caliper and remove the caliper mounting bolts.
3. Remove the old brake pads and inspect them for uneven wear.
4. Install new brake pads, ensuring they are properly seated.
5. Reinstall the caliper and secure it with mounting bolts to the manufacturer’s torque specifications.

3. Check and Resurface/Replace Brake Rotors

Sub-steps:
1. Check rotor thickness with a micrometer; replace if below minimum specifications.
2. If rotors are warped, either resurface them or replace with new rotors.
3. Clean the rotor surface with brake cleaner before installation.
4. Reinstall the rotors and ensure they are secured properly.

4. Inspect Suspension Components

Sub-steps:
1. Visually inspect control arms, bushings, and tie rod ends for signs of wear or damage.
2. Replace any worn or damaged components as necessary.
3. Ensure all bolts are tightened to manufacturer specifications.

5. Tire Balance and Alignment

Sub-steps:
1. Remove the wheels and take them to a tire shop for balancing.
2. Have the alignment checked and adjusted as needed.
3. Reinstall the wheels, ensuring they are torqued to specifications.
