Attorney, Agent or FirmInternational ClassesB60T 13/567 (20060101)B60T 13/52 (20060101) AbstractA brake actuation assembly (10) wherein a front shell (50) of a booster mechanism (14) is attached to a stationary bulkhead (32) and the housing (58) of a master cylinder (12). On actuation of the booster mechanism (14) an output force is produced to operate the master cylinder (12). The operation of the master cylinder (12) develops a corresponding reaction force which is directly transferred into the stationary bulkhead (22) to substantially eliminate any axial deformation in the rear shell (20) of the booster mechanism (14). | |
