braking woes

[stevewix]

hi all, i've got an 85 m1009 cucv that i recently swapped 1 ton axles onto. i thought it braked weird before, swapping the axles confirmed my suspicion, the rear brakes aren't getting any kind of pressure. i can't gravity bleed them, it acts like the line is kinked or the proportioning valve is screwed up. i'm 99% sure they never worked right from day one, so i would rather inspect master cyl, etc.

the rear has a new pro-comp brake line, so the rubber one isn't collapsed or anything.

ideas? questions? post up!

Are the lines kinked?

I had a pain in the ass braking problem and went through 3 masters. I broke off a fitting on the MC and replaced the hardlines to it, and it seems to work fine now on stands

You can try gettin a used master so you can start throwing parts at it, I got them from members for cheap cheap

hey thanks, after bleeding the brakes 4 TIMES then using a suction bleeder i finally got an enourmous air pocket out of the systemworks!

Hooray!

I fell out of my truck last time I bled brakes
