Well, the master cylinder is tasked with supplying hydraulic pressure to the braking system. So when you initially step on the brake pedal the linkage activates a piston within the system and this piston then displaces hydraulic fluid.
In this case, you will just have brake function to two of your four wheels. People also ask us about single reservoir master cylinders versus dual reservoir master cylinders and basically they just want to know if there is an advantage to using dual reservoir master cylinder versus the single reservoir master cylinder.
