Solution

1. Preparation

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

2. Inspect and Replace Brake Pads and Rotors

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect the brake pads for thickness; replace if less than 3 mm.
3. Check the rotor for scoring or warping. If warped, replace the rotor.
4. If replacing, clean the caliper bracket and apply anti-seize lubricant to the mounting surface.
5. Install new brake pads and rotors, ensuring proper orientation.
6. Torque the caliper bolts to manufacturer specifications (typically around 25-30 ft-lbs).

3. Check and Adjust Wheel Alignment

Sub-steps:
1. Use a wheel alignment tool to check the alignment settings.
2. Adjust the toe and camber as necessary to meet manufacturer specifications.
3. Perform a road test to ensure the steering wheel is centered.

4. Inspect and Balance Tires

Sub-steps:
1. Remove tires and inspect for uneven wear or damage.
2. If uneven wear is detected, rotate or replace tires as necessary.
3. Have tires balanced using a tire balancing machine.

5. Brake System Flush (if necessary)

Sub-steps:
1. Use a brake fluid bleeder to remove old fluid.
2. Replace with manufacturer-recommended brake fluid.
3. Bleed the brake lines to remove any air bubbles.
