I just purchased a 1989 Reatta with no apparent major issues, or so I thought. However, after driving the car for about an hour, the red brake light and the amber abs light will come on. The brakes still continue to work for a little while. I thought it might be the accumulator failing, so I replaced that. Then I drove the car to work, thinking all was good. On the ride home, there was a lot of traffic, so a lot of braking. The hydraulic pump motor was overheating, causing the pressure to be really low, so I had to take 15 minute stops to let the motor cool down. Anyone have any ideas?
