	Listmembers:

	I own a 1987 Audi Coupe GT with the late NG engine.  While driving
the
	Continental Divide yesterday I suddenly heard a 'hissing' sound
coming
	from beneath the dash.  The hissing sounds like either air escaping
or
	being sucked in through a small hole.  This sound stops immediately
when
	the brake pedal is depressed, but returns the instant I lift off the
	brake.  Today I disassembled the lower dash to reveal where the
brake
	booster push rod goes through the firewall, and started the engine
	again.  The sound is apparently coming from this seal where the rod
	leaves the passenger compartment.  The sound in almost inaudible
from
	the engine compartment.

	Questions:  Which parts do I need to replace?  Do I need to replace
the
	booster, master cylinder, and regulator, or just the seals on either
	side of the brake booster mount?

	I have priced the following items, and was wondering if these prices
	sound reasonable.  Master Cyl. $149, Brake Booster $199, Regulater
$90.
	All from Blaufergnugen.

	Any assistance in diagnosis or repair procedure would be greatly
	appreciated as I am hoping to head up to Glacier Park in Montana
early
	next week.  Much thanks in advance.  ALP.
