Solution

1. Preparation

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

2. Lift the Vehicle

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

3. Remove Wheel

Utilize a lug wrench to loosen and remove the wheel nuts.
Remove the wheel to access the brake assembly.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check for uneven wear or thickness below the manufacturer's specification.
Replace Brake Pads (if needed):
- Remove the caliper by removing the caliper bolts with a socket set.
- Slide the caliper off the rotor and support it with a bungee cord to avoid stressing the brake line.
- Remove the old brake pads and replace them with new ones, ensuring they are properly seated.

5. Inspect and Replace Brake Rotors

Inspect Rotors:
- Measure rotor thickness with a micrometer; replace if below specs or if warped.
Replace Rotors (if needed):
- Remove the caliper bracket using a socket set.
- Slide off the rotor; clean the hub surface.
- Install the new rotor, ensuring it is secured properly.

6. Reassemble Components

Reattach the caliper bracket and caliper, tightening to manufacturer specifications (typically 20-30 ft-lbs for caliper bolts).
Reinstall the wheel and torque lug nuts to the specified value (usually 75-85 ft-lbs).

7. Lower the Vehicle

Remove jack stands and lower the vehicle using the jack.

8. Test Brakes

Pump the brake pedal to set the pads against the rotor.
Test drive the vehicle to ensure vibrations are resolved.
