Solution

1. Preparation

Gather tools and parts: OBD-II scanner, jack and jack stands, lug wrench, dial indicator, torque wrench, and replacement brake pads and rotors if necessary.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

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 lug wrench.

3. Inspect Brake Components

Rotors:
- Remove the caliper by unbolting it from the bracket.
- Slide the caliper off the rotor and suspend it using a bungee cord (do not let it hang by the brake line).
- Measure rotor thickness and check for warping with a dial indicator; if warped or below specifications, replace.
Brake Pads:
- Inspect the brake pads for thickness; if worn unevenly or below specification, replace them.

4. Replace Components (if necessary)

Rotors:
- If replacing, remove the old rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
- Install the new rotor, ensuring it is properly seated and secured.
Brake Pads:
- Install new brake pads into the caliper bracket, ensuring proper orientation.

5. Reassemble Braking System

Reinstall the caliper over the new pads and rotor.
Torque caliper bolts to manufacturer's specifications (typically around 25-35 Nm, check service manual).
Reinstall the wheel and torque lug nuts to specifications (typically around 120 Nm).

6. Lower Vehicle & Test

Carefully lower the vehicle and remove the jack stands.
Test the brakes gently to ensure proper function before road testing.
