Electronic system of distribution of brake effort (EBV)
Audi A4 does without a traditional regulator of brake effort for back wheels. Instead of mechanical or hydraulic management of pressure hydraulic module ABS for electronic distribution of brake effort (Elektronische Bremskraft-Verteilung) is used. It is carried out by the block of management ABS.
The block of management by means of the gauge of number of turns supervises delay of each back wheel and compares sizes of a forward and back axis. If at braking distinction between number of turns of forward and back wheels too big pressure upon brakes of back wheels decreases by means of electromagnetic valves in the hydraulic module. In such a way excessive braking of a back axis is not supposed, Audi remains in a track.
