Nice car - is that Sahara? I once had a similar 1600-2.

Odd that the pedal doesn't come back up.

One thing that can happen with rebuilt cylinders is that if bore has pitting, or rubber seal gets damaged on installation, fluid is simply pushed back over the seal instead of going out the pipes. So no fluid loss, just recirculation. Just a thought.

What did you mean by "check valve"? On the manifold?

+1 on this, it sounds like an internal leak to me. If you have disturbed the brake pedal /linkage then the MC may have been operating on a pitted part of the bore it may not have seen before.

Swap that, bleed well and then drive the crap out of your beautiful car.

Thanks guys!

Turns out, the booster is messed up. I've always read about the vacuum loss when they die, but mine wasn't traveling smoothly and was hanging up on a portion of the travel, making it difficult to press the pedal and then stick once it was down. Looking inside, it may be that the diaphragm was damaged and is binding somehow...either way, I'll be picking up Steve's!

With the booster out of the equation, the pedal movement was very smooth, and I replaced the mc with a known good one and found the issue was only with the booster in the equation...I took the booster off and tested it by hand and found the sticking problem..I'll follow up once I replace it and bleed everything...;-)
