did you find the ABS. Here is one for almost $1000 see the link below. I am having problems with mine and looking for one also but can't afford that one so I am going to do other recommendations to try to fix mine. the pedal went to the floor. https://www.rockauto.com/?mfr=CARDONE&partnum=123411

Hey I just run across you post since I am having problems with my antilock brake unit, the one with the accumulator on it, I have added one picture here. My vehicle is a 1988 buic riviera T-type 2 door coupe 3.8 engine. I can not cough up the $1200 hundred or so that they charge for a rebuilt unit so I was thinking of replacing it with a " regular booster and a regular master cylinder" and just forget about the 4 electrical plugs that are plugged to the antilock unit, I don't wouldn't really mind if I see a bunch of red alarms as long as the vehicle stops when I step on the pedal . Lol. can you give me your thoughts and may be tips since you already have experience dooing this. the main problem I am thinking is if the 2 lines into the original unit will fit into the new regular master cylinder. Thanks.

trying to fix this problem I did purchase a accumulator but still did not pick up any pedall pressure, I am going to put 12v to the pump motor as you mention if I can figure out which unit is that one, Lol and as for the pressure switch and the relay I am going to need to get me a book to tell me what they are. I found a rebuilt unit but it will cost me about $1200 total so I am looking at all options, even replacing for a regular booster and master cylinder. Thanks for you input.

Thanks, I will email them and see if I can get some help from them

Thanks a lot for your help.

Thanks for your great input I wish I had your knowledge. yeah this car was amazing since we bought it brand new, one owner, us; This buick, solid, powerful with amazing electronics was way ahead of its time when designed. Yeah I am trying to go the safest way to fix it since its no fun the pedal going to the floor on you. I am 66 yrs old now and I just drive it to the supermarket and the theather and the beach once in a while so if I can't get this brake unit overhaul or find me a good replacement; the Christmas lights in June, would cheer me up a little I would say. jajaja

Thank you, I was going to bleed at the tires and never thought about the master cylinder bleeding so thanks for the tip, I will do it and we'll se what happen.

lost my brakes, the pedal went to the floor, I replaced the high pressure accumulator but it did not help. Does anyone have one for sale or is there a place that someone can recommendo to buy one?. Do I need to bleed the brakes for the accumulator to work ??, I included a stock picture of the unit in my 1988 buick riviera 2 door sedan T-type I was thinking of replacing that unit for a regular booster and a regular master cilynder brake and just leave the electrical lines disconected and just be a mechanical unit like other buicks. can you guys comment on this thought. Thanks
