On my '89 GM daily driver. I had to change out a caliper (RF) because the piston would not retract enough to get new pads installed.
Also the flex hose was splitting from age so I changed that at the same time.

Everything went smooth until it came time to bleed the brakes. I must have done close to a 100 pump & hold reps and it still had a few bubbles burping out every other try.
The master never came close to going dry, and everything was fine before I took the line apart at the wheel house. I gave in and bled the opposite wheel after I had run a half a quart of fluid through the repaired side. A very small bit of air spit out that (LF) side when I first tried it but it cleared out right away.
Went back to the RF and STILL getting 2-4 bb sized bubbles two out of three reps.

Finally gave up and put the wheels back on to give it a field test.
The car stops, but the stopping distance is not very impressive. And the pedal definately has a spongy feel to it when it did not beforehand.

My lines are NOT rusty, and I have never had an issue with fluid loss.
Triple checked all the fittings are tight, I'm formally ASE certified.

Any ideas?
