Could the cups on one end be pushed in too far & past the inlet hole? Maybe need adjusting or the push rod is too long. I take it the spring is in the center, then the cups, then the pistons with the recess in the pistons faceing out. The type of fluid would not matter. If you are applying pressure with the drums off you may be blowing the cups out.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
