Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Wear safety glasses and gloves.

2. Remove Wheel Assembly

Sub-steps:
1. Loosen the lug nuts slightly before lifting the vehicle.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Sub-steps:
1. Check brake pads for even wear; replace if worn unevenly.
2. Inspect rotors for signs of warping or scoring; replace if necessary.
3. If rotors are warped, measure thickness; replace if below the minimum specification.

4. Resurface or Replace Rotors

Sub-steps:
1. If rotors are within spec but warped, have them resurfaced at a machine shop.
2. If replacing, install new rotors according to manufacturer specifications.
3. Clean the rotor surface with brake cleaner before installation.

5. Reinstall Brake Pads and Wheel

Sub-steps:
1. If pads are worn, replace them with new ones, ensuring proper orientation.
2. Reinstall the caliper, tightening bolts to the manufacturer’s torque specifications (usually around 25-35 ft-lbs).
3. Place the wheel back on and hand-tighten lug nuts.
4. Lower the vehicle and fully tighten lug nuts in a star pattern to the specified torque (typically 80-100 ft-lbs).

6. Final Checks

Sub-steps:
1. Pump the brake pedal a few times to seat the pads against the rotors.
2. Check brake fluid level and top off if necessary.
3. Test drive the vehicle to ensure brakes operate smoothly without pulsation.
