My brakes started giving trouble and the ABS symbol on my 1990 Reatta would occasionally come on. Not feeling up to it, I took the car to a brake specialist that I have used for over thirty years. They said it was throwing a code 48, and I would need a "control unit". Turns out the Teves specialist no longer works there. They said they couldn't find any parts at all after much searching. So after spending $180, I took it home. First thing I found was that the accumulator must have a broken bladder as the pump comes on as soon as you press the pedal. My mechanic made no mention of this. Since the car is a daily driver, I couldn't wait for some of the other suppliers to get their stocks replenished, so I bought one for a Jaguar from eBay for $330 including priority mail. It is supposed to be the exact same part that the Reatta uses. I'll report back when I install it.
