Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, OBD-II scanner, run-out gauge, caliper gauge.
Safety Warnings: Ensure the vehicle is on level ground and the parking brake is engaged.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Loosen lug nuts and lift the vehicle with a jack.
2. Remove the wheel to access the brake assembly.
3. Check the brake rotor for warping using a run-out gauge.
  - If warped beyond manufacturer specifications, proceed to replace.
4. Remove the caliper by unscrewing the caliper mounting bolts.
5. Slide the caliper off the rotor and hang it securely without stressing the brake line.
6. Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
7. Install the new rotor and ensure it is seated correctly.
8. Reattach the caliper and torque the bolts to manufacturer specifications.

3. Inspect and Replace Brake Pads

Sub-steps:
1. While the caliper is removed, check the brake pads for thickness.
2. If pads are worn unevenly or below the minimum thickness, replace them.
3. Remove the old pads from the caliper bracket.
4. Install new brake pads, ensuring they are oriented correctly.
5. Reassemble the caliper over the new pads and torque the bolts.

4. Wheel Alignment and Balance

Sub-steps:
1. After reassembly, take the vehicle to a professional for a wheel alignment check.
2. Ensure all tires are balanced correctly.
