Brakes...when in 4-low

[jk_surgeonfish]

I think I found part of the issue. If I jack the rear up and start, put in drive and hit the brakes only one of the rear drums will stop. I think I will just redo both the drum brakes in the back with new wheel cylinders. I used the MityVac to bleed the system and noticed on the wheel that fails to stop it did not bleed as easily. New lines were put in the rear a few years ago.

It will stop both if I pull the e-brake. I suspect a bad rear wheel cylinder. There is no leaking however.

Thanks for everyone's help. I will post up once I rebuild the drums.

sounds like a possible prop valve problem too.
