Solution

1. Preparation

Gather necessary tools and parts for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Raise the Vehicle

Use a jack to lift the front of the truck and secure it with jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Components

Brake Rotors:
- Remove the brake caliper using a socket set.
- Take off the brake pads and set them aside.
- Inspect the rotors for warping by checking for grooves or uneven surfaces.
- If warped, replace the rotors with new ones (follow manufacturer specifications for rotor thickness).
- Torque the caliper bolts to the manufacturer’s specifications.
Brake Pads:
- Check the thickness of the pads; replace if below minimum thickness.
- Clean the caliper bracket and apply brake grease to the backing of the new pads.

4. Inspect Suspension Components

Check control arms, ball joints, and bushings for wear.
Replace any worn components as needed (use manufacturer-recommended parts).
Reassemble any components removed during inspection.

5. Reassemble and Lower the Vehicle

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
Test the braking system for functionality before driving.
