Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a lug wrench.

3. Inspect and Replace Brake Rotors

Inspection:
- Check rotors for warping using a dial indicator.
- If warping is detected (typically more than 0.002 inches), replace the rotors.
Replacement:
- Remove the caliper bolts and slide the caliper off the rotor.
- Remove the rotor by unscrewing the retaining screws (if applicable).
- Install the new rotor and secure it with retaining screws.
- Reattach the caliper and torque bolts to manufacturer specifications (usually around 80-100 ft-lbs).

4. Inspect and Replace Brake Pads

Remove the brake pads from the caliper bracket.
Inspect for uneven wear; if the pads are worn unevenly or below the recommended thickness, replace them.
Install new pads, ensuring they are properly seated in the caliper bracket.

5. Check Suspension Components

Inspect control arms, bushings, and tie rods for any play or damage.
Tighten or replace any worn components as necessary.

6. Wheel Alignment and Balance

Have a professional alignment performed to ensure proper tracking.
Balance the wheels to eliminate vibrations from unbalanced tires.
