[s-cars] S4 brake issue

[Rit bellis]

I just did my bomb 6 months ago.  The hardest part was finding the darn thing.  its most likely the bomb, but other posters have good tests for the servo, which is mucho pricey.  I'm going to need to replace mine soon, as replacing the bomb made the light go out, but hasn't fully restored function.> From: Ken at hartleys.net> To: s-car-list at audifans.com> Date: Tue, 20 Nov 2007 15:37:47 -0700> Subject: [s-cars] S4 brake issue> > Greetngs> > Got the cylinder head back on the S4, took a while but I replaced every single potential wear part while doing it. New water pump, idler pulley, crank gear ( its keyway was missing ) and on the first few cranks she purred to life. Took about 15 min for the lifters to calm down, then all is well.> > Here is my question, my " bomb " was marginal before the car hibernated, I was at about 4 pedal pushes, NOW the light is on constantly, and there is a pulsation felt with light pedal pressure, and occasionally the brakes are just gone, as if the car were not running at all. I need a source for rebuilding this one, or a good used one, or could it be the valve going to it? Could a few months of sitting kill a bomb? Can they be reawakened? Thoughts?> > Incidentally, all the bizarre electrical gremlins with the power windows, locking spontaniously, and the mystery relay at the drivers feet clicking for days when the car is off, have vanished, although I came no where NEAR the interior, nor the grounds of the car, except of course the 4 small browns at the back of the fuel rail....> > Thank you!> Kenneth Hartley> 1993 S4 pearl> Ken at hartleys.net> > _______________________________________________> S-CAR-List mailing list> S-CAR-List at audifans.com> http://www.audifans.com/mailman/listinfo/s-car-list
