I just replaced the rear calipers as one was sticking. Bleed rear calipers and everything looked good. Better half held pressure on brake. She didn't tell me that it went to the floor. Now no brakes at all, peddle goes to floor. Bleed all caliper and things look fine. Still pedle goes to floor with almost no resistance. Help?

First, make sure to take the resevoir cap off where the brake fluid goes.
Two, keep the resevoir topped off while bleeding brakes.
Three, start w/ the farthest caliper from the resevoir (usually the right rear) and work your way around until you do the last caliper (should be the driver's side front)
Four, when you bleed, pump the pedal a couple of times and tell your "better half" to keep her foot on the pedal as you crack the bleed valve - pedal should go to the floor. Repeat as necessary until just fluid comes out - no air (keep checking the resevoir, fill it if necessary!), move to the next caliper and repeat the process....

After you do this and you still have the brake pedal go to the floor and not hold pressure - then you are looking at replacing the brake master cyclinder.

Thanks, It looks like the master-cylinder. Rebleed all as you suggested. I had the rear calipers off for a while and alot of fluid drained out due to Autozone giving me the wrong caliper and driving all over Ga. to get the right ones. Will replace master in the AM. I'll let ya know if it works. Thanks

Here are 2 great articles I've found on bleeding brakes:

Someone else on the forum may be able to better explain the ABS-end-of-things when it comes to flushing & replacing old brake fluid...
