This lightly used 77-875 master cylinder was a part of a brake pad and rotor dynamometer. It was used to actuate a tilton clutch to disengage from the electric drive shaft. It was a way to free spin the inertia wheel. Overall it was used very minimally. It has never been mounted in any vehicle. It works fine and included is a stainless steel -3 adapter for fluid out. Also an aluminum adapter with a -4 male AN reservoir inlet.
