Hi, I have a 94 Eldorado, and after I changed the rear brake line that was leaking, I bled the brakes and can get a decent pedal with the engine off, once I start the car the pedal will drop to the floor. I also have an ABS light that is on, (been on since I got it) and something about the traction control but forgot exactly what it says. I imagine this has something to do with it. I am not that familiar with these cars, I was reading about the Alante brake system and how to diagnose it, are these similiar as my Eldo? I have not driven this thing yet, it had been sitting and wouldn't start when I bought it and have been working somethings out of it. I bled the RR first then LR then RF then LF. When I bled it, it didn't have as much pressure coming out of the bleeders as I thought it should have.
Any help with this is greatly appreciated.
Thanks in advance,
AL

I get a code of T027 (LF speed sensor) will this cause this problem that I am getting?

BIG No ! The Allante ABS is unlike anything else in the Cadillac line.

The ElDo should be bled completely, all wheels; make sure the reservoir remains fulla t all times while bleeding.

Basically, following standard bleeding routines as any other car.

Allante NOT included !

ok great, i am going to bleed them again tomorrow,

Thanks, AL

Does parking brake work? If not, it can effect bleeding / pedal feel. ABS unit can get air pocket(s) to bleed it dealers scanner required. When trying to diagnose concerns without correct manual you can get way off tract. If you have to find manual of sister car(s). In this case you are limited to 93-95 Seville or 94-95 DeVille Concours even this info may not be accurate in all cases.

never tried the parking brake, by the way, where is the release for the parking brake?

It should release automatically when shifted in to gear, there is also a manual release on side of pedal assembly.

I kept bleeding, this time with the key on if it makes a difference, and have about 1/3 of a pedal, now on to th eABS and LF sensor issue, I posted some pics in the gallery if anyone is interested.
