The legs (52, 52'. . . 52N) which extend through slots (55, 55'. . . 55N) in the shell (30) of the brake booster (12) have tabs (54, 54'. . . 54N) that lock the housing (38) to the shell (30). The disc (56) has an annular rib (58) which engages the shell (30) to form a seal to prevent air from entering chambers (24, 40). The housing (38) is connected to a source of vacuum and a flapper (60) positioned over a plurality of openings (32, 32'. . . 32N) in the shell (30) to allow vacuum in the chamber (40) to evacuate air from the brake booster (12).</p> |
