Abstract
Tandem type vacuum brake boosters require a connection between their vacuum chambers. According to the present invention this connection is provided by the housing having crosspieces parallel to the longitudinal axis of the housing disposed about the periphery of the housing with channels formed between the crosspieces to enable the two vacuum chambers to communicate with each other.
