The master cylinder is a critical component of your braking system. If it begins to fail you will experience a softer, spongier pedal feel. You can also experience a pedal that slowly sinks towards the floor when it is depressed. If you check your brake fluid and notice it is dark brown or black, odds are the cylinder seals have deteriorated and the fluid has been contaminated.
