The cost savings and energy advantages of conventional brake systems equipped with a pneumatic brake booster can also be applied to advanced vehicle technologies such as future downsized engines and hybrid/fuel cell vehicles by incorporating a vacuum pump. These pumps are able to supply the necessary vacuum independent of the engine technology. The UP30/32 supplies a vacuum to the brake booster, and when required, to the engine compartment actuators. The UP30/UP32 is installed in the pneumatic section of the brake system, just like the UP28. Both vacuum pumps are ideal for vehicles without any vacuum, such as hybrid/fuel cell, electric or diesel engines.
