Solution

1. Preparation

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

2. Lift the Vehicle

Using a jack, lift the front of the vehicle and secure it on jack stands.
Remove the front wheels to access the brake components.

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Use a dial indicator to measure for warping.
- If warping exceeds manufacturer specifications, replace the rotors.
Replace Rotors:
- Remove caliper bolts and slide the caliper off the rotor.
- Remove the old rotor by unscrewing the retaining screws (if applicable).
- Install the new rotor, ensuring it is seated correctly.
- Reattach the caliper over the new rotor and torque caliper bolts to manufacturer specifications.

4. Inspect and Replace Brake Pads

Inspect Pads:
- Check thickness and condition of the brake pads.
- If worn unevenly or below the minimum thickness, replace them.
Replace Pads:
- Remove the old pads from the caliper bracket.
- Apply brake grease to the back of the new pads and install them into the bracket.

5. Inspect Suspension Components

Check control arms, bushings, and struts for any signs of wear or damage.
Replace any worn suspension components to ensure proper alignment and stability.

6. Reassemble and Lower Vehicle

Reinstall the wheels and lower the vehicle back to the ground.
Torque the wheel lug nuts to manufacturer specifications.
