Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Front Wheels

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

3. Inspect and Replace Brake Rotors

Inspection:
- Use a dial indicator to measure rotor runout; replace if exceeds specifications (typically 0.002 inches).
Replacement:
- Remove caliper bolts using a socket set.
- Suspend the caliper with a hook to avoid strain on the brake line.
- Remove the rotor by unscrewing the retaining screws if present.
- Install new rotors, ensuring they are properly seated and secure.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Check the caliper slides for corrosion; clean or replace as necessary.
Apply brake grease to the backs of the new pads.
Install new brake pads into the caliper bracket and ensure they are properly aligned.

5. Reassemble Components

Reinstall the caliper over the new brake pads.
Torque caliper bolts to manufacturer specifications (typically 20-25 lb-ft).
Reattach the front wheels and hand-tighten the lug nuts.

6. Lower Vehicle and Torque Lug Nuts

Lower the vehicle off the jack stands.
Torque the lug nuts to the manufacturer’s specification (typically 100 lb-ft).
