Diagnosing a Bad Master Cylinder or ABS Module – What You Need to Know

A bad master cylinder or ABS module can cause a variety of issues with your vehicle’s braking system. If your car is having issues with the brakes, it is possible that the master cylinder or ABS module is to blame. A bad master cylinder can cause a lack of response when engaging the brake pedal, as well as a spongy feeling when engaged. The ABS module, which controls the anti-lock brake system, can also cause problems such as a grinding sound when attempting to stop and an intermittent “ABS” light on your dashboard. Both of these components are essential for safe operation and should be inspected if you are experiencing any problems.
