ABSTRACT:
The stop member (23), which forms a bearing surface (33) cooperating in abutment with an abutting member (22) carried by the actuating rod (13) of the booster so as to determine the operational dead travel of the booster, has a deformable structure (30) capable of yielding elastically when a pulling force (F) exerted axially by the abutting member (22) on the stop member exceeds a predetermined value. The deformable structure advantageously consists of at least one arm (30) integral with a mounting sleeve (28), fixed by crimping (37) onto the rear central duct (9) of the rear shell (2) of the booster housing. The abutting member (22) is secured, in a given position, to the coupling fork (15) of the actuating rod (13).
