Brake releasing mechanism and brake system

An embodiment of a gerotor apparatus includes a housing including a first member. The first member includes a brake pin aperture formed therein. The apparatus also includes a brake pin at least partially interposed within the first member. The brake pin includes a first annular surface and a second annular surface. The first annular surface defines, at least in part, a first brake chamber. The second annular surface defines, at least in part, a second brake chamber. A first fluid introduced into the first brake chamber will urge the brake pin in a first direction. A second fluid introduced into the second brake chamber will urge the brake pin generally in the first direction.
