WebFalse - Friction opposes motion and eventually will cause an object to come to a stop. The strength of the force of friction depends on two factors: 1) The types of services involved. 2) how hard does services push together (Against each other) True/False - rough surfaces produce greater friction then smooth surfaces. True. WebHydraulic System. arrangement of pistons and tubing that uses fluid pressure to transmit force from one part to another. Brake pedal assembly. a lever arm to increase the force applied to the master cylinder piston. Master Cylinder. a foot operated pump that forces fluid into the brake lines and wheel cylinders. Cup.
