Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Safety warning: Ensure the vehicle is in "Park" mode and the wheels are chocked.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the front or rear wheels, depending on where the issue is suspected.

3. Inspect Brake Pads and Rotors

Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor.
- Inspect brake pads for uneven wear; replace if below manufacturer specifications.
Brake Rotors:
- Check for warping by using a dial indicator or visual inspection.
- If warped, replace with new rotors. If scoring is present, consider resurfacing if within limits.

4. Reinstall Components

Reattach the caliper and tighten the bolts to manufacturer torque specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and lower the vehicle back to the ground.
Tighten the wheel lug nuts to manufacturer specifications (usually around 100-120 ft-lbs).

5. Brake System Bleed (if necessary)

If brake fluid was disturbed, bleed the brake lines using a brake bleeder kit to remove air from the system.
