Brake Booster died!

Well today's drive home was interesting needless to say! I was about halfway home when both my ABS and ebrake light came on. I figured the relay was just acting up again and I still had brakes. I made a stop off to look at fuel guages. When I turned my car back on I had no power brakes. I shut it off and tapped the relay, got the booster going agin but still had both lights on. Stopped again at dairy queen for some burgers, started back up no booster again. Tried tapping the relay, inpecting wires, etc. etc. Ended up driving the rest of the way home with no power brakes.

This is the worst possible time for this to happen since the ford dealers are all closed. I have to drive to work tomorrow somehow and I'm supposed to be moving tomorrow afternoon.

Can anyone give me a suggestion on what to do here? anyway for me to jumper the booster power? just to test to make sure the relay is what failed? Any ideas/input/help would be greatly appreciated guys. Can I use just like a 30a relay temporarily atleast to get me to a ford dealer that has a relay in stock??

Sorry Pete, I actually thought it was the ABS relay causing me problems. Turns out I was wrong. I should have done more research before posting this time, was just frustrated. Was just hoping someone would give me a way to run the booster without the relay so I can track down the parts tomorrow.

Guess I'll just put in some 10ga wire with a switch and use that to control the pump to get myself to work tomorrow (I'm assuming if I jumper the T/Y and GY/R terminals the pump will run). Again sorry for posting easily answerable questions without searching first. It wont happen again.

The pump relay isnt anything special.... just a generic Ford 80s era relay. Should be available at places other than Ford, like NAPA, etc. FYI, the offical name for the relay is the "anti skid relay", even though the pump relay has nothing to do with the ABS.

The ABS power relay and pump relay are the same part, so switch out the ABS power relay for the pump relay, and you will get power brakes back, but will, of course, loose tha ABS function.

thanks Jeff, I'll give that a try to get me to auto zone at 12:00. After cross referencing every part number I have with what I can scrounge up on here I'm still not sure which one I need. I ordered a RY46, RY71, and RY223. I believe those are blue streak relay numbers, I'm not sure no one I've called has given me much info.
