Solution

1. Preparation

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

2. Lift the Vehicle

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

3. Inspect and Replace Brake Rotors

Inspection:
- Remove the brake caliper using a socket wrench.
- Inspect the rotor for warping or scoring. Use a runout gauge to check for warping.
Replacement (if necessary):
- Remove the rotor by unscrewing the retaining screws.
- Install new rotors, ensuring they are properly seated.
- Torque rotor screws to manufacturer specifications (usually around 10-15 lb-ft).

4. Inspect and Replace Brake Pads

Remove old brake pads from the caliper bracket.
Clean the caliper bracket with brake cleaner.
Install new brake pads, ensuring they are properly aligned.
Apply anti-squeal lubricant on the back of pads if specified by the manufacturer.

5. Reassemble Components

Reattach the brake caliper and torque bolts to manufacturer specifications (typically around 25-30 lb-ft).
Reinstall the wheels and lower the vehicle.
Torque wheel lug nuts to manufacturer specifications (usually 80-100 lb-ft).
