Electrohydraulic Braking (EHB) gets rid of the vacuum booster and replaces the current modulator with one that includes a high pressure accumulator.
Like the Hydro boost system it uses an accumulator to provide the required pressure to activate the master cylinder, however, it uses electrical power to effectively “charge” the accumulator and build sufficient pressure for efficient brake operation. This system means that less power is taken away from the engine during operation as battery power is used, and that there is no chance of problems caused by things such as a worn power steering pump, slipping or broken pump drive belt, or hose connections.
