Tested my vacuum pump and it was pulling between 1-2 inHg at the pump. Explains why my brakes were firm to say the least. Got a new Wabco and I can move the piston in and out a little over a quarter inch. After that no movement and no spring return. Just want to make sure this is correct before...

Searched everywhere, but can't find an answer The vacuum pump calls for one gasket, but there's a metal plate under it, and I don't know wether to put the gasket above or below the metal plate.
