i did a caliper swap on the vette - 1991 - fronts only. i had each hose off for about 20 seconds, reconnected and opened bleeders to gravity fill the calipers before bleeding them via mityvac and then by the make your wife sit in the car and pump the pedal method.
i have a spongy pedal that goes to the floor slowly while holding it. i have never had to bleed the rears on any car with just a front caliper swap. i am getting no air out of the fronts at all - and am going to bleed the rears to rule that out - but what could i be overlooking? no leaks at the fittings or hoses, and the only part of the system disturbed was the hose to caliper connection. i've been bleeding brakes for years from simple repairs to building complete systems from scratch and never have had an issue like this.
