I have had an impossible time to keep brake pressure.I assumed that one or both replacement calipers were assembled incorrectly when re-manufacturing took place.I found one that had mis-matched punch marks.I replaced it with another.That was the front right.Now, when the system is bled fluid squirts out of the bottom brake line fitting at the caliper, even the nipples look fine.Fittings are snug.

I see a difference even though punch marks on left front caliper are the same.
The upper inside valve faces inward towards engine and the lower bleeder faces toward rear of the car.The right front is the opposite.
I cant understand why it leaks when brake pedal is depressed.You hear fluid squirting out and quite a bit in 3 or 4 pumps.All fittings are seated snugly.
Do I need to try another caliper.Ive been fooled by the punch marks?


Thanks to anyone in advance,
