Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks for safety.

2. Remove Wheel

Use a lug wrench to loosen wheel nuts while the vehicle is on the ground.
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Inspection: Use a dial indicator to check rotor run-out; if the run-out exceeds specifications (usually 0.002-0.003 inches), they may need replacing or resurfacing.
Replacement:
- Remove caliper bolts and detach the caliper (support with a bungee cord, do not let it hang).
- Remove the old rotor by unscrewing retaining screws (if applicable) and sliding it off the hub.
- Clean the hub surface before installing a new rotor.
- Install the new rotor, ensuring it is seated correctly.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Installation:
- Apply brake grease to the back of the new pads to reduce noise and ensure smooth operation.
- Install the new pads in the caliper bracket.
- Compress the caliper piston using a brake caliper tool to make space for the new pads.

5. Reassemble Components

Reinstall the caliper over the new pads and secure with bolts to the specified torque (typically around 20-30 ft-lbs).
Reattach the wheel and tighten lug nuts in a star pattern to the manufacturer's specifications.

6. Final Checks

Lower the vehicle and remove wheel chocks.
Pump the brake pedal to ensure proper engagement before driving.
