Thank You, Neil:

Yes, there was air coming from all four bleeders when bleeding.

The problem started the instant the bearings were replaced, so must be related to that process somehow. The only thing I can figure is when removing the caliper a brake line end could have been compromised� but yet, we are losing no fluid at all.

Thanks,
