ABSTRACT:
A brake servo booster has a housing (1) divided into two chambers (A, B) by a movable partition (5) which includes a diaphragm (6). A protective boot (14) for a support member (11) extending through the housing is connected to the diaphragm by a carrier member (16) engaged by adjacent portions (14A, 6A) of the boot and diaphragm in a manner which avoids direct contact between these portions and facilitates assembly of the booster.
