Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Remove Wheel

Use a lug wrench to loosen lug nuts while the vehicle is still on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection: Remove the caliper by unbolting it from the bracket.
- Inspect the brake pads for thickness; replace if less than 3mm.
Replacement: If necessary, slide the old pads out and insert new pads into the caliper bracket.
- Ensure they are seated properly.

4. Check and Resurface/Replace Rotors

Inspect the rotor surface for grooves or roughness.
If damaged, either resurface the rotors or replace them with new ones.
Resurfacing: Use a brake lathe according to manufacturer specifications.
Replacement: Remove the rotor by unbolting it from the hub.

5. Reassemble Components

Reattach the caliper over the new brake pads and torque bolts to manufacturer specifications (usually 20-25 ft-lbs).
Reinstall the wheel and torque the lug nuts in a crisscross pattern to the specified torque (typically 100-110 ft-lbs).

6. Test Brakes

Lower the vehicle and pump the brake pedal several times to ensure proper brake pad seating.
Check for any abnormal noises or issues during the first test drive.
