Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Tools Required: Jack, jack stands, lug wrench, torque wrench, brake rotor measuring tool, brake pad gauge.

2. Raise the Vehicle

Use a jack to lift the front and/or rear of the vehicle.
Securely place jack stands under the vehicle for safety.

3. Remove Wheels

Use a lug wrench to remove the lug nuts and take off the wheels.
Safety Warning: Ensure the vehicle is securely supported by jack stands before working underneath.

4. Inspect and Replace Brake Components

Inspect Rotors:
- Measure rotor thickness with a measuring tool. Replace rotors if below minimum thickness specifications.
- Check for warping by placing a dial indicator on the rotor surface; replace if warped.
Replace Brake Pads:
- Remove caliper bolts and slide the caliper off the rotor.
- Remove old brake pads and replace with new ones, ensuring they are oriented correctly.
- Reinstall the caliper and torque bolts to manufacturer specifications (typically around 25-30 ft-lbs).

5. Reassemble and Lower the Vehicle

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (usually around 100-130 ft-lbs).

6. Test Drive

After repairs, test drive the vehicle at low speeds to ensure vibrations have been resolved.
