We just found it. It is the brake fluid sensor. It'* not reading the fluid leval and sending that signal back to the ABS pump relay

If someone will, take a look at this drawing and see if you can tell me what # 18 is called.
I think it is the brake fluid sensor but not sure. When I know for sure I can order one from somewhere or call around to find it. It is a Teve System

Thanks, Jess

Since there is a computer as such in my 1988 Bonneville SSE, is there a plug in, in the car where I can read the codes? If so where is it located?
Thanks, Jess

1 big question, is the ABS warning light even working in this car? It should come on when you first turn the key on. If it doesn't, that may help explain it. Our Bonneville (1990 SSE) had a failed pressure accumulator (the bowl on top). What would happen would be that you would step on the brake pedal, the brake light and ABS light would come on almost at the same time. The pedal would be rock hard, as if the system that provides the ABS feedback was holding the pedal at the top. As you held the brake pedal, it would allow the pedal to be pressed further and further down, thus allowing more and more braking. If you held the pedal at a certain place, the lights would go out. If you let off the pedal, it would work fine. The connector for pulling the ABS codes is by the drivers feet, but I don't recall the exact procedure. It involves crossing 2 wires to get the codes flashed out, but different then retrieving engine codes. If your ABS light is not working at all, you are unable to pull codes.

The yellow (amber) ABS light never goes out. I can put power to the pump and charge the system and all that goes out is the red brake light. about the 4th or 5th time I hit the brake ped. the red light comes back on and all the brake fluid is in the resavoir. When I charge the pump I can watch the fluid level drain down to the full line. It will stay there for days if I don't hit the ped.so it is staying charged.

1 problem.
my wheels not compatibility with news upgrades.... i put the oem wheels olds cutlass supreme 89.

Result: ver very very strong and hevy brakes! (and end of the drums problem)
the bonus: EBC 3gd rotor (front), EBC yellow stuff (front and rear), metallic hoses (anti-fading) fluid ebc to up 300 celcius

heavy duty brakes!!! in all moments, all!
