Abstract

In a tandem servo booster provided with a pair of ties (26, 27) extending through the housing (1) and diaphragm assemblies (7, 8) for transmitting braking reaction forces from the master cylinder housing (41) directly to the vehicle bulkhead, the ties are tubular and are provided with axially spaced ports (29, 30) to provide fluid communication between pairs of alternate booster chambers (23, 25; 22, 24). In another construction both ties provide fluid communication between the same two booster chambers, and the other two chambers are connected together by a tubular member which is secured to the diaphragm support plate of the front diaphragm assembly and extends rearwardly through a partition wall of the housing positioned axially between the two diaphragm assemblies. <IMAGE>
