Review on Improved Beck Arnley Brake Master Cylinder - 072-9571 by Jay Chenier

I got this for my Corolla 07. The container is different from mine. This MS is for a car with a slave cylinder (this information should be in the description). Had to use my old tank for it to work. after installation, the new brake fluid turned black. Looks like the washers in the MS are worn out. In a few days. the pedal began to disappear intermittently. I bought it because of the title and it was a new piece. Reinforces the old adage, "Just because it's new." Doesn't mean it works.
