94 1/2 ton 12v mushy brakes

[ktmracer21]

back ground on problem: new rear brakes, (drums on chrysler 9.25) new rr wheel cylinders. bled all four corners witht the 2 man method. new seal kit on vacuum power steering pump. seal kit for vacuum pump on the way. new line from vacuum pump to booster, hose clamped both ends.

basically you have to pump the pedal, it gets good hard pressure but if you leave your foot on it slowly sinks down...i located the vent/weep hole in the booster and seems dry. also fluid level does not decrease.


what the phuck should i throw at it now?

ideas? thanks!
