The master cylinder is one of the most important parts of the brake assembly system. The master cylinder is considered as the starting point in a hydraulic brake system. Simplifying it, mechanical force applied from the brake pedal is turned into fluid force from the master cylinder. Some or the other time, most of us experience a soft, sinking brake pedal. Quite a time, the cause can be the brake master cylinder. To avoid this scenario careful and timely inspection of the brake master cylinder is essential and this can be done with little knowledge of the system. However, if you don’t have time for it, go in for assistance and help from a reputed brake service center in your area.

With basic knowledge of the brake system, checking the master cylinder is fairly easy. In most  of the cases seen, a  faulty  master  cylinder  tends to leak  externally  out the  rear  piston  or  leaks internally. You  are  able  to detect   external   brake   fluid   leaks   by   checking   the master cylinder  boot  for  fluid  or  dampness  on  the firewall. During an internal leak, the brake pedal will move slowly to the floor making you pump the brakes often. Inoperative valves in the master cylinder are also a reason for faulty working of the brakes.
