Why is my anti lock brake light on?
The anti-lock brake system is a complex configuration of computers and sensors. When all of the components are working in perfect harmony, it ensures a quick, reactive system that can improve braking control under all surface conditions. Faults in this system are often first indicated by illuminated lights in the gauge cluster.
Why do I need to change my brake pads?
I decided to replace the rotors, figuring turning them would be useless considering the warpage (vibration) was only felt when the brakes were hot. Figured turning the rotors while cold would not affect or eliminate the warpage. So anyhow, new Raybestos PG Plus rotors and Raybestos Quiet Stop ceramic pads did the trick…no more vibration!
Can a brake job cause the ABS light?
