Friction material monitoring and stopping system integrity checks on the 2023 Cadillac CT5 are managed by mechanical wear indicators, visual rotor checks, and brake fluid level sensors.
How to Fix It:
-
Listen for Warning Noises: Watch for a high-pitched squealing sound when braking, which indicates that the built-in mechanical wear indicators are rubbing against the rotor.
-
Inspect Brake Pads Visually: Look through the wheel spokes or remove the wheels to check the remaining thickness of the brake pad friction material against backing plates.
-
Monitor Fluid Levels: Check the brake fluid reservoir under the hood regularly; a dropping fluid level often correlates with natural brake pad wear over time.
