waltmail Posted March 8, 2005 Share Posted March 8, 2005 I've got a rock hard pedal with no braking power on my '89 Reatta. CRT display says brake pressure low. I am of the opinion that I need to replace my accumulator. Does anyone have a write up or suggestions/tips? Is it as simple as it looks? Link to comment Share on other sites More sharing options...
padgett Posted March 8, 2005 Share Posted March 8, 2005 Even with a bad accumulator, the pressure should come up/red light goes out so long as you do not touch the brake pedal. I think you have a different problem (does it say brake *pressure* or brake *fluid* low ?). Link to comment Share on other sites More sharing options...

Jim Posted March 8, 2005 Share Posted March 8, 2005 If you determine which parts you need, I have good used accumulators, pressure switches, pump and motors or whole complete ABS units. I can be reached at jfinn@cpinternet.com Link to comment Share on other sites More sharing options...
harry yarnell Posted March 8, 2005 Share Posted March 8, 2005 This has nothing to do with the accumulator. Your pump isn't running. MOST likely cause: bad pump relay, bad pressure switch, bad pump motor. In that order. Could be something else, but these cover 90% of the known reasons.

padgett Posted March 8, 2005 Share Posted March 8, 2005 I suspect your pump is not running then (both red and yellow lights should be on continuously). Most common problem is a bad brake pump relay. Was just a discussion on that.. If not the relay, could be wiring, pressure switch, or motor (in order of increasing expense). Each of these is individually replaceable but requires some troubleshooting to determine what is getting power. Link to comment Share on other sites More sharing options...
waltmail Posted March 13, 2005 Author Share Posted March 13, 2005 It is cured. Turned out it was one of the relays. Can't be specific as to which, as I replaced them both and was elated and left well enough alone. Thanks for the insight. Link to comment Share on other sites More sharing options...
