I purchased this vacuum pump for the soul purpose of bleeding auto brakes. I thought that it would be a quick, clean, easy way for me to do brakes by myself. It did flush the two rear brake cylinders. It did not actually create a vacuum reading on the gauge. It did suck a huge amount of air around the bleeder  screws with the brake fluid. (No amount of grease or liquid gasket material stopped the leaking.) I had to constantly pump the vacuum pump trigger to get the fluid out. The bleed hoses are stiff and the fluid holding container is light. If you are not holding the container in your hand it will tip over and allow fluid to leak into the vacuum gun. It is messy to clean up. And the case that holds everything is so light that the case tips over and spills all the fittings all over the place. I regret ever purchasing this item. (NO matter the cost.) I flushed my front brake calibers the old fashion way. My daughter pumped the brakes while I bleed the fluid through a hose to a container. I strongly recommend against purchasing this item.
