Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake rotor and pad replacement tools, caliper tool, OBD-II scanner.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the braking system.

2. Remove the Wheel

Loosen the lug nuts with a lug wrench while the vehicle is still on the ground.
Raise the vehicle using a jack and support it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Check for warping using a runout gauge or visually inspect for grooves or uneven surfaces.
- If warped, remove the rotor bolts and take off the rotor.
- Replace with new rotors if necessary, ensuring proper installation torque.
Inspect Brake Pads:
- Remove the caliper by unbolting it from the bracket.
- Check the brake pads for thickness; replace if worn below the minimum specification (usually 3mm or less).
- Install new brake pads, ensuring they are properly seated in the caliper bracket.

4. Reassemble and Adjust

Reinstall the brake caliper over the new pads and tighten bolts to manufacturer specifications (typically around 26-34 ft-lbs).
Reattach the rotor if it was removed, ensuring that it is properly secured and torqued.
Reinstall the wheel and hand-tighten the lug nuts.

5. Final Checks

Lower the vehicle and tighten the lug nuts to the manufacturer's recommended torque specifications (usually around 100-120 ft-lbs).
Reconnect the battery.
