The Klingon Brake Warning alarm came on today. It was not the low fluid level, but the other one. Does this mean the accumulater is on the way out? Brakes feel OK and I know the pads are good.

That sensor is for the fluid level. That is not the brake warning I am getting. Anyone else have any idea on how to diagnose a brake warning message and how to check the accumulator.

The Klingon Brake Warning is still coming on every time we drive the car. I have disconnected the battery but that didn't work. The warning stays on until you turn the engine off and restart it again, then it stays off. Don't really know how to test it anything from this point. I know it isn't the low fluid level because (a) the sensor is disconnected at the master cylinder and (b) the klingon translates differently for fluid level. Anyone have any ideas on how to further diagnose this warning. The brakes feel and drive normal.

OK, thought it was Ok because the alarm went away but it is not. The accumulator or pump thingy is still running all the time. This means either the pump is faulty or the system has an internal leak. Either or both sound intimidating. Anyone had these parts out and can give me some tips?

Gary, if the pump is running all the time and the accumulator is a new fully charged unit then the fluid from the pump must be going somewhere; are you losing fluid or can you see a leak? There's a small rubber shute under the pump at the motor end so that any leak that passes back from the pump along the drive shaft can drain out and not get into the motor. Also with the accumulator fully charged the pump should cut out on pressure so your pressure switch could be stuffed. If that's ok and the accumulator isn't at pressure but the pump is running continuously to make pressure then the pressure could be getting lost through the master cylinder. Is the brake pedal spongy? Did you introduce air into the system when the accumulator was changed?

The pump was running all the time before I changed the accumulator and we thought the accumulator was the problem, which it obviously wasn't. So anything I did when changing it isn't the problem eg introducing air etc. It has never lost a drop of brake fluid in the past 10 years. It is as if the pump is making any pressure at all because when I turn the engine off, the pump continues to wind down for about 20-30 seconds and sounds like someone hitting the side of an oil tin with a spanner, but not as loud as that but same sound. Also when in the car you can hear the pump and accumulator running when ever the brake pedal is touched, something that was never evident before. This is a real mystery for me so all help is appreciated. I will post in wanted section and see if anyone has a pump for sale as i have to start somewhere

Maybe then the brake fluid isn't getting to make pressure but is circulating somewhere or the pump can't make enough pressure because it's rooted. So sometime in its life the brake fluid was really crap to cause wear. I posted a description with photos a few years ago of what the pump insides looked like, do a search if you want as I've tried to find them on my computer but failed.
