Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Lift the Vehicle

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

3. Inspect and Replace Brake Rotors

Inspect the Rotors:
- Remove the wheel using a socket set.
- Measure rotor thickness with a caliper; replace if below specifications (usually below 1mm of minimum thickness).
Replace the Rotors:
- Remove caliper bolts and lift the caliper away from the rotor.
- Remove the old rotor and install the new rotor, ensuring it is seated correctly.
- Reattach the caliper and torque bolts to manufacturer specifications (usually around 80-100 ft-lbs).

4. Inspect and Replace Brake Pads

Inspect the Pads:
- Check the thickness of the brake pads; replace if worn down below 3mm.
Replace the Pads:
- Remove the caliper bracket bolts to access the pads.
- Slide out old pads and insert new pads, ensuring they are properly aligned.
- Reattach the caliper and torque bolts to specifications.

5. Check and Replace Suspension Components (if needed)

Inspect Components:
- Check control arms, bushings, and other suspension parts for wear or damage.
Replace Components:
- Use a socket set to remove any worn parts.
- Install new parts and torque to specifications.

6. Wheel Alignment and Balance

After replacing the brakes and checking suspension components, drive to a professional for a wheel alignment and balance if necessary.
