Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Gather personal protective equipment (gloves, safety glasses).

2. Remove Front Wheels

Loosen lug nuts slightly while the vehicle is still on the ground.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the front wheels.

3. Inspect and Replace Brake Rotors (if warped)

Inspection:
- Use a dial indicator to measure rotor runout.
- If warping is detected (greater than 0.002 inches), proceed to replace.
Replacement:
- Remove the caliper bracket by unscrewing the bolts (usually 12-17mm).
- Slide off the old rotor and install the new rotor, ensuring it is seated properly.
- Reattach the caliper bracket using the specified torque (typically 80-100 ft-lbs).

4. Inspect and Replace Brake Pads (if worn)

Check the thickness of the brake pads.
If worn below the manufacturer’s specification (usually 3 mm), replace them.
Remove the caliper by unbolting it and slide off the old pads.
Install new pads and reassemble the caliper, ensuring correct alignment.

5. Check Suspension Components

Visually inspect tie rods, control arms, and bushings for wear or play.
Replace any damaged suspension components.

6. Perform Wheel Alignment

After completing brake work, have the vehicle's alignment checked and adjusted as needed.
