kcirtap,
Happened to me too...many years ago in Germany. I purchased an older used VW Variant Wagon which had a braking problem and I could not get the brakes bled? Took the car to a local German mechanic who showed me that someone had replaced the driver side caliper with a passenger side caliper and the bleed screw was at the bottom....can't get the air out. I had two right front calipers installed????
His trick was to remove the caliper, insert a block of wood to act as a spacer for the rotor, turn the caliper bleeder screw up and bleed the brake, remove the block of wood and install the caliper back in the upside-down position the way it was originally installed. Caliper worked fine and my car passed inspection....:grin:
Depending upon the mounting bolts and where the brake hose is mounted to the caliper, not all vehicles allow the calipers to be mounted on the wrong side, and almost impossible to mount them upside-down.
