You know, I don't know this particular model but I'm going to guess that the brake is released by a vacuum diaphragm somewhere right above or connected to the parking brake itself. So i would suspect a vacuum leak (leaking hose) or diaphragm assembly. You MUST have a manual release in there somewhere.

Well...this is not a job you should tackle unless you have the tools and manuals...SO, I'm NOT giving you advice here on how to fix this, only to mention a few things. What is probably happening is that on your car the primary brake system and ABS system are not being bleed at the same time. In some early ABS you need a tool (like a meter) to recycle the ABS pump so that all the old fluid and air is purged out of the ENTIRE system. So I think your ABS pump is continually contaminating your brake system because you can't control it. I don't know what the GM tech was thinking unless you've run your ABS pump while it was dry. That would not be good. But I don't see why a good GM tech couldn't go through all the bleeding procedures and see what's what from there.

I own a 1999 Seville SLS, 30,000 miles. Yesterday the automatic garage door opener failed to work; the light next to the buttons did not go on and the transmitter failed to open the door. This morning, same hour, it's working. This is the second time in about a month for this new, intermittent problem. Any ideas? Any solutions? (I also posted this on the general forum for cadillac).
#7 of 436 1996 STS, the engine seems to stop and start at by nickc Nov 08, 2004 (9:05 am)
I am puzzled by the occasional 'mysteries that happen with this car. On long trips, say 200 miles or more when the car is well warmed up, Cruise control can be off or on, RPM is at about 2675 to 2750, the engine very quickly seems to shut down and restart. So it really like a surge except the RPM's do not go up they go down about 1500 RPM and them the car is back to humming along. It might do this three times in a row over a minute or once every three minutes. Any thoughts? I've noticed at this point if I stop on the side of the road the RPM's will read anywhere from 1500 to 2200 and will only go back to 750 or so if I shut the car down wait a few minutes and then it will be normal for awhile. Thanks for any insight!
#11 of 436 '04 Seats and Mileage by jgmilberg Feb 09, 2005 (1:08 am)
The motor will improve mileage after 6000-8000 miles. The car should have synthetic oil in it from the factory if you change it to regular oil it should seat faster that the 8000 miles, but after that I would go back to synthetic. The reason for this is that about 2 years ago they had an problem with the engines using too much oil and they ended up with a new piston and ring combo that takes a little while to seat into the cylinders. The seats are different that the ones in your '01 base Deville. The '04 model has heated and cooled seats, and the way they are designed the cooling fans built into the seat make it a little firmer at first, but they do "break in" so to speak.
