Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Gather safety equipment such as gloves and safety glasses.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure with jack stands to ensure safety.

3. Remove the Wheel

Use a lug wrench to remove the lug nuts.
Carefully take off the wheel and set it aside.

4. Inspect and Replace Brake Rotors

Inspection:
- Use a dial indicator to check the rotor for warping; replace if beyond specifications (typically 0.002 inches).
Replacement:
- Remove caliper bolts using a socket set.
- Slide the caliper off the rotor; support it to avoid stress on the brake line.
- Remove the old rotor and replace it with a new one, ensuring it is properly aligned.
- Torque caliper bolts to manufacturer specifications (usually around 25-35 ft-lbs).

5. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Clean the caliper bracket with brake cleaner.
Install new brake pads, ensuring they seat properly.
Apply brake grease to backing plates if required.

6. Reassemble and Lower the Vehicle

Reattach the caliper and tighten bolts to specifications.
Replace the wheel and hand-tighten lug nuts.
Lower the vehicle and torque lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

7. Test Drive

Perform a test drive to check for any remaining vibrations while braking.
