Brake Master Cylinder in Cadillac Escalade cars is literally the heart in braking system that translates foot force into hydraulic pressure. This hydraulic pressure is handed down to the slave cylinders and in turn apply pressure to the brake hence creating the needed friction to cause a halt on the car. In most cases, it comprises the pistons in a cast iron or aluminum body, while having an external tank for fluid level replenishment and to minimize air admittance. Cadillac Escalade models employ dual circuit master cylinders so that if one circuit gives out, the other can offer brake power. It is also safer for this reason as hydraulic failure will not put a halt the entire operation of the design. Though there have been changes to the features of the master cylinder by the use of different types of reservoir and housing, the basic working of this part remains the same for different models. It is important to have periodic services to avoid cases of leakage and to have the Brake Master Cylinder fully operational.
