Default 89 XJ with brake problems

i recently put new calipers on, put new shoes on and turned my drums, replaced the master cylinder as well, now im having problems. on level ground my brakes work excellent, on any incline front or rear, my brakes go right to the floor and i cant build up pressure. im going crazy trying to figure this one out, any ideas??????????

It kinda sounds like an air bubble in your system, if so on an incline it'll be rising towards the master cylinder.

Check your fluid level and bleed them.

the fluid is full. i bled them like crazy before. the reason i replaced all this stuff was because the peddle was going to the floor, i replaced all this stuff and no fix. the guy i took it to said it was the rear brakes being too far out of adjustment, the first couple pumps were just getting the shoes out to the drums, he adjusted them and they work great except for the incline problem now. how many cycles of bleeding do you think it would take to get thru the longest line? (pass rear)

dumb question but did you check that none of your flexible lines are bulging under pressure?

no i didnt, might be a difficult one to spot huh? i suppose now would be a good time to order stainless lines and then re-bleed to eliminate that possibility?
