[DeTomaso] Brake booster vacuum

The air in all boosters is filtered at the pedal push rod and that filter quiets down the vacuum noise that is going on. One of the test of a bad booster is its 
affect on the no load idle which of course indicate a larger than designed vac leak.
Fixed a MGB today that had a loose filter because the customer stated he heard a large sucking noise upon brake pedal touching.
