Review on Pneumatic Brake Fluid Bleeder Tool with 4 Master Cylinder Adapters - KUNTEC, 90-120 PSI by Luis Shreibman

so I took that to make changing the brake fluid easier when changing front calipers. Pumping worked well, no complaints. It uses a lot of air and takes a lot of time on the rear wheel. The good thing is that you can do it on your own and you don't have to push the master cylinder outside of normal areas of use, perhaps by nicking or cutting the diaphragm. The fancy brake fluid bottle didn't work for me. Whatever adapter I try, it never attaches properly to my tank. I used it as a refill bottle as it had better control over draining fluid straight from a regular brake fluid bottle. I did notice it leaking out of the valve a bit, but since I wasn't using it as a "hands-free" bottle, it didn't matter much. If I lose this one, I will most likely buy another one. Now go wait the brakes.
