Brake/Steering & Radio Antenna

Mike, yes.  There's the famous "grenade", a hydraulic accumulator 
located in front of your LF tire.  It stores hydraulic-source power 
and assists both brakes and steering.  It is a failure point on both 
Audis and BMWs, as it's on both.  What you're describing MAY be a 
failing check-valve in the accumulator, or it may not.  Might just be 
low fluid in the large hydraulic reservoir.but DO NOT use brake 
fluid!!   This takes a special fluid, Pentosin.  Here's one check (as 
described to me by Audi folks in Austin, TX:

1)  Drive @20 MPH in an area away from traffic.  If possible, put one 
side on gravel, the other on pavement.
2)  Dynamite the brakes and come to a full stop.  This is intended to 
energetically engage the anti-lock brakes.  (I think your 87 has 
3)  If the brake warning light comes on, it indicates your check 
valve is not doing its job and the sudden demand on the system 
combined with loss of engine speed is allowing the accumulator to 
dump its stored-up assist.

Or at least this is how I understand it.  Anyone have a more accurate 
description, or have I actually figured this out right???

Bob, you are luckier than I.  I CANNOT figure out for the life of me 
why Audi adopted that (IMHO) STOOPID in-the-windshield antenna idea 
after GM tried it during the 70's and found out it sucked.  Our 200T 
with that antenna has the worst AM reception, bar none, of any 
vehicle I have ever driven.  Honest to god, I go places EVERY DAY 
where I can pick up AM stations better on a **$50 hand-held 
Walkperson** than on my multi-superdollar-high-zoot Audi with Bose 
stereo!!  It really pi**es me off!!!  And I'm talking about using the 
hand-held radio INSIDE THE D**M CAR!!!!! This is the ONLY setup I 
have observed in 20+ years of working in radio and TV in which I get 
FM stations interfering on AM!!  Wow.  I'm really impressed!!

Stupid, stupid, stupid.  I really miss the antenna I had on my 5KT.  I 
am going to have a local stereo shop deface my beautiful pearl-white 
fender and install a REAL motorized antenna so I have have some 
function besides a tape player that says Bose on it.  (Yeah, the FM 
reception is better than AM - it's passable - but the signal range 
still SUCKS!!)
