ABSTRACT:
A pump including a main body having a piston provided in a portion of the main body, the piston being configured to reciprocate linearly. A piston spring may be provided within the main body and configured to bias the piston toward an end of the main body. Further, a plurality of intake check valves may be positioned radially within the main body and configured to move in a direction generally perpendicular to the linearly reciprocating direction of the piston such that brake fluid is introduced into the main body. Additionally, the pump may include an exhaust check valve configured to exhaust brake fluid from an inside of the main body to an exterior of the main body by moving an exhaust check ball in the linearly reciprocating direction of the piston.
