Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, dial indicator, torque wrench, brake cleaner, safety goggles, gloves.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Lift the Vehicle

Use the 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

Check for Warping:
- Attach the dial indicator to the brake rotor.
- Rotate the rotor and check for runout; anything over 0.002 inches indicates warping.
Remove Old Rotors:
- Unbolt the caliper and hang it securely without straining the brake line.
- Remove the rotor by unbolting it from the hub.
Install New Rotors:
- Clean the new rotors with brake cleaner to remove any protective oil.
- Install the new rotors and torque the mounting bolts to the manufacturer’s specifications.

4. Inspect and Replace Brake Pads

Remove the brake pads from the caliper bracket.
Check for even wear; replace if any pads show significant wear.
Install new brake pads according to the manufacturer's guidelines.

5. Reassemble and Torque Components

Reattach the caliper to the rotor and torque the bolts according to specifications.
Reinstall the wheels and torque the lug nuts in a star pattern to the specified torque.

6. Lower the Vehicle

Carefully lower the vehicle back to the ground.
Recheck the torque on the lug nuts after the vehicle is lowered.
