Brake Release

Brake Release





At the end of the anti-lock stop, when the brake pedal is released, the pump will remain running for a short time to help drain any fluid from the accumulators. As this fluid returns into the system, the spring forces the piston back to its original position.
The isolation valve opens and fluid may return to the master cylinder. Conventional braking is then resumed.
