Guest chrismc410 Posted August 8, 2015 Share Posted August 8, 2015 Hi, I know this site is dedicated to the Reatta and this is my first post. With that said, I know they share the same Teves II ABS system from what I've read thus far. Here is my problem: Brake pedal is hard and ABS light and Red Brake Light is on on the dash when the car is on and will not go out. ABS pump will not run when key is turned to on or ignition. ABS pump will work if 12V DC is ran from the battery directly to the pump. If I let the pump run long enough both lights on the dash go out but they come on if plug the pump back in as normal and use the brake pedal. ABS fuses on fuse block are good From what I've read here it can be the accumulator, pressure switch, relays or all three. My questions are as follows: 1. Where is the ABS main and ABS pump relay on the 1990 Buick Electra Park Ave. Ultra? It's not under the hood or under the black plastic near the windshield wiper. Pics would be appreciated if possible. 2. I know the parts are very difficult to impossible to get OEM or from most aftermarket. I have seen some accumulator balls that say they are compatible. Where do I find one? 3. What pressure switches are compatible? The original is not available anymore and I have seen a similar one but has a different pin out. If worse comes to worse can this pinout be converted? And if so, what pin out is what to the other The pin out is like this on the original --- --- --- --- --- The replacements I see look like this: --- --- --- --- --- I really need to get this fixed even a temporary measure as this is now the only car I have, though I have very strong feet don't want to keep driving it like this. My choices are reduced to the following: 1. Junk the car and replace it with a newer one. I don't want to do this since it otherwise runs fine and is in decent shape but I will if no other feasible options exist. 2. Convert the brake system to conventional vacuum assist. I will need a shop willing to do this as none around my area is willing.. If you know of one who can and has a lead on a Buick Electra/Lesabre/Park Ave without ABS that can part with the whole brake system, lines and all, I will consider that option. Thanks in advance.
