An anti-lock brake apparatus, method and article including a compact, fast, modulator (10) in a brake fluide conduit between a master cylinder reservoir and a brake cylinder. The modulator includes a pump (80, 88) for pumping fluid back from the brake cylinder to the reservoir in response to a particular sensed rate of retardation and a valve (112) for isolating the pump from the brake fluide passageways through the modulator during non-pumping periods. The modulator includes a plurality of separate passageways therethrough, one for each wheel or set of wheels and releases pressure in one wheel while reapplying it to another while the pump is continuously running, without one action affecting the other. |
