No rear brakes argggg!!!

[jcboal]

so i swaped a complete rear subframe from a '87iS to my '84 318. i used ABS caliper, but just cut the line for the connectors. got everything hooked up and tried to bleed the brakes....nothing out of the bleeders.
i decided to take it to a local tire shop to have them vaccum bleed them. i pick it up they tell me it is all set. i thought so to till i was on a wet road and my front tires locked up...no rear brakes.
i thought maybe the proprtioning valve need to be changed. so i swapped it out and tried to bleed the real calipers again....still nothing. well i checked where the had line meets the rubber line and there if fluid there, but none to the calpier on either side.

so my questions:
1) would the ABS sensor have anything to do with this?
2) Are plugged brake lines that common on these cars? (i have never had one on the 40 other cars i have owned)
3) Any other ideas on how to fix it? (no rear brakes in the snow, is not that much fun)

try unbolting the outer hoses and hitting the brakes... see if fluid comes out

1. no
2. possible
3. you already know you have fluid up to the calipers, so it must be the line after it or the calipers.

having done this swap 2+ years ago, I didn't have to change the prop. valve below the booster or anything else, but I did use new lines.

I'm having a similar problem, where nothing is coming from the rear calipers. I've confirmed that the lines aren't blocked and am stumped why no fluid is reaching the back when bleeding. I've tried pressure bleeding, vacuum bleeding and the 2 person method to no avail.
