Imagine starting your car or driving down the road and all of a sudden the brake warning light comes on. This is a strong indication that something is wrong with your braking system. Sometimes this could be a simple issue that requires simple fix but sometimes it could be a safety issue that could be life threatening. Usually when you start your car, all the warning lights initially come on while the onboard computer runs a check. Each time a particular system is checked to be working fine, the warning light responsible for that system goes off. This continues sequentially until all the warning lights go off. But in a case where the brake warning light comes on, there is a problem. We will look at possible causes of this and proposed fixes to this problem.
