%#*Brakes

Well I replaced all the calipers, finally got all of them bled out . Opened the garage and looked on the floor to find brake fluid under two of the tires. What gives here. Did I really get two bad calipers? This can't be normal. They are still under warranty, but its just the agravation

Oh that can't be good.

Is it the caliper pistons or the bleeder valve or the brake line or ????

I know that I had to make my bleeder valves pretty tight so that they wouldn't leak, but I have speedbleeders in there. I would be REAL careful about tightening them though.

I took the rear wheel off. Looks like the bleeders are OK. Must be a piston. Oh Nooooooo

Did you replace the flex lines when you did the calipers? You may also want to check to be sure the steel ines from the flex to the caliper are in good shape and properly seated. Both of these are prone to failure and the steel lines are a booger to seat sometimes.
It's possible the new calipers are bad, but check all your connections first.
