Abstract
A flywheel driven by the differential ring gear of a vehicle senses rear wheel velocity and deceleration rates. A modulating unit includes an accumulator and a pump driven by the same shaft that drives the flywheel from the ring gear. A brake fluid accumulator stores brake fluid during each brake release cycle. The pump pumps fluid from the accumulator into the rear brakes to restore the original brake actuating pressure during each reapply cycle. Pressure from the master cylinder is blocked by movement and position of the accumlator piston during the release and reapply cycles. Orifices control the rate of pressure release and apply.
