An apparatus for mounting a brake booster on a wall, the booster having a push rod extending from a rear surface of the booster through a hole in the wall, the booster also having a breather port surrounding the push rod, the apparatus comprising:
- a mounting surface of the wall disposed about the hole in the wall adapted for receiving the rear surface of the booster;
- and
- an air passage in the wall adapted for providing fluid communication from the breather port to air surrounding the booster when the rear surface of the booster is bearing against the mounting surface.
