<p>An antilock braking system having a permanent reduced flow bypass passageway (22) provided in parallel with the isolation valve (20) to reduce the feedback to the brake pedal (18) during an antilock mode of operation. In the preferred embodiment, the permanent fluid bypass passageway (22) is provided internal to the isolation valve (20). The fluid bypass passageway (22) connects the input fluid passageway (104) to the output passageway (136) in parallel with the valve member (130) controlling the primary fluid flow through the isolation valve (20).</p> |
