Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Wear appropriate safety gear (gloves and safety glasses).

2. Lift the Vehicle

Use a hydraulic floor jack to lift the front of the vehicle.
Secure with jack stands for safety.

3. Remove Front Wheels

Use a socket set to remove the lug nuts and take off the front wheels.

4. Inspect and Replace Brake Rotors (if warped)

Inspect Rotors:
- Check rotors for warping using a dial indicator.
- If warping is evident (more than 0.002 inches), replace the rotors.
Remove Old Rotors:
- Unscrew the caliper bolts with a socket wrench and remove the caliper.
- Secure the caliper with a bungee cord to avoid strain on the brake line.
- Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install New Rotors:
- Clean the new rotors with brake cleaner to remove any protective oil.
- Install the new rotors and secure with retaining screws.

5. Inspect and Replace Brake Pads

Remove Brake Pads:
- Remove the old brake pads from the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the backing of the new pads.
- Install the new pads into the caliper bracket.

6. Reassemble Brake Components

Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer’s torque specifications (typically around 25-35 ft-lbs).
Reattach the front wheels and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications (typically around 76-80 ft-lbs).
