ABSTRACT:
A vehicle braking system including an antilock braking system or a traction assist braking system, or both, operatively coupled therewith, is disclosed. The system includes a pump assembly including a housing defining a main bore, an inlet bore, and an outlet bore. A reciprocatable piston is retained in the main bore. An inlet check valve is operable to pass fluid to the outlet bore when the piston reciprocates. An outlet check valve is inserted into the outlet bore and operates to pass fluid from the pump assembly when the piston reciprocates. A deformable flange extends sufficiently outward from a valve body of the outlet check valve. The flange secures the outlet check valve within the outlet bore when the flange is deformed into displacing engagement with the outlet bore. Further, a method of securing a valve in a bore of a pump assembly is disclosed.
