Pump delco supreme 11 brake fluid or equivalent dot-3 fluid up to the halfway point of the reservoir from clean labeled containers. Make sure the fluid end points dip completely under fluid. Depress and release the primary Piston with a smooth round tool up to 25 mm in Piston travel as fluid flows from the ports to complete this procedure. Decreased movement of the primary Piston needs more force while the bleeding process clears trapped air. Repeat this step until fluid appears without air pockets in the openings. Reinstall all parts back into the reservoir space after taking the hoses and master cylinder reservoir cap out. Lastly pull the fittings off their ports with the hoses and put a clean cloth over the master cylinder while dismounting it from the vise.

The Brake Master Cylinder as a part of GMC Yukon automobiles plays the role of halting the car and transforming the force applied by the foot to hydraulic pressure. This hydraulic pressure is taken to the slave cylinders where it in turns activates the push rods which apply the brakes exerting the required friction to halt the automobile. Usually, the GMC Yukon is equipped with a dual circuit master cylinder and that is why even in case of a malfunction of one circuit, there will be enough force to break. Since the inception of the product, GMC has used both cast iron and aluminum Brake Master Cylinder housings; the reservoirs, however, are either integral or externally mounted depending on the model. The currents integral reservoirs contain one threaded cap, while the external ones may contain one or two caps at most. In any case, the construction of the master cylinder does not differ; thus, the brake performance for the GMC Yukon will not be compromised. It is also important to regularly service the system since leaks and internal flaws will adversely affect the outcome of braking.
