Lost almost all brake pressure on my '72 daily driver yesterday evening. If I pump the brakes I can build pressure temporarily to stop the car, and I'm convinced all four calipers are working. No evidence of fluid leaks anywhere, and there is brake fluid in the reservoir. Anything to suspect OTHER than a failed MC?

I've a 19mm ATE in the shopping cart here at Pelican ready to buy. I guess I would need the two rubber grommets as well. Anything else? Also, I saw one reviewer "complain" that the new 19mm has a one pole pressure switch instead of the two pole. I haven't looked at mine recently, but it's probably the "old" one, so is there a solution there?

TIA!
