I had a rear brake failure, and I have now repaired the problem. However now I still have no rear brakes and the Brake Warning Light is on all the time. I suspect that the problem is in the dual master cylinder and I have no idea how to determine if it is working right or if it needs to be reset after the failure. And if it does need reset how do I do it?
