Some engines don’t produce enough vacuum to operate servo assisted brakes and other vacuum dependant system to their optimum. This is particularly true of engines that have high lift, long duration camshafts.
This system generates vacuum independently from the engine. This means that the vacuum supply is kept constant regardless of engine RPM and load. This constant depression results in a consistent weighting to the brake pedal in all conditions. The increased vacuum levels that can be achieved with this system can allow less pedal force to be exerted by the driver to achieve the same or more retardation on the brakes.
This system utilises the UP5.0 Hella vacuum pump to achieve maximum vacuum quickly and efficiently. The pump is of a vane type construction and is therefore much quieter in operation than an equivalent sized piston pump.
The pump is controlled by the adjustable pressure switch and a micro relay. The pump system is protected by a 20 Amp circuit breaker.
This system has been designed to be universal and can provide enough vacuum for up to two servos. It can be used on any vehicle that utilises a pneumatic servo to assist braking including hybrid and fully electric vehicles. It is capable of replacing the original vacuum system on a vehicle or can be used to supplement the original system.
