Anyone have a copy of Range Rover ABS Brakes Explained they would like to share? Troubleshooting a pump issue and believe the problem to be the check value. Would like some other info before tearing into the pump.

The check valve was unseated. But the accumulator is shit too.

It is. I'm getting a BRAKE light and a TC light, and the pump runs almost non-stop. In fact the pump quit. I ended up tearing into the thing thinking it was fried and I wanted to better understand how everything worked. But I was able to repair the unit. So now, fingers crossed, the accumulator is the final piece of the non-working brake puzzle.
