2nd Gen Non-Engine/Transmission Need help with brakes

[Rosshatfield]

my brakes are not working in reverse. The brake light and abs light come on when I hit the brakes while backing up. Also the brakes will go completely away. The peddle gets hard and the brakes fail. Once I go a few feet forward they come back. I have not found an obvious vacum leek. I have bled the brakes a few time and they look visiouly fine. I am at a lose, any ideas would be appreceated. I dont care how far fetched they are.

Thanks

You don't say what type vehicle this involves but I will guess that it has rear drums??? You probably need to remove the drums as it sounds like a wheel cylinder has failed. I don't think the ABS is even activated at that slow speed. bg
