Just got the brake system done on my '46 Chevy Panel and I'm having trouble bleeding the system down. The master cyl. and booster is from a '77 Granada, the front is 11" M II, the rear is a Ford 9" with 11" X 2 1/2", the proportioning valve is from a 80's Chevy 1/2T PU. Doing the one man bledding with a vacum pump. At first I couldn't get anything at all on the rears then depressed the pedal a little and got them bled alright. Went to the front and can get nothing at all. Checked the MC and pumped the pedal a couple of times and I can see the return flow in the rear brake portion of the MC but the front brake part of the MC does nothing.
Anyone have a direction for me to go in from here??

Thanks
David

Sounds like you didn't do a 'bench prime'. Did you pump the MC on the bench with tubes circulating fluid back into the reservoirs? You can get these kits @ auto parts stores. I have even had cheap plastic ones come with a rebuilt MC. If you don't do this step, the MC can air lock and will never move any fluid! Vacuum bleeders can suck air past the lips of the piston seals so you never sometimes get fluid from the MC that way.

Thanks Willy's, that got it. Went back and redid the bench bleed and got one last little blurp out and it started working right. The one man bleeding isn't working so good. Got a little pedal but not much so I'll wait till one of the daughters gets home from school, a little homework project.

Thanks again.

Yep, that really got it. 15 YO daughter came home and helped me bleed the system and now have half a pedal on power brakes without the engine running. Daughter just got her permit and now had a lesson on how brakes work, and she asked for the lesson

Great, thanx for the update. Next to solving electrical problems bleeding brakes is the most voo-doo thing we have to do!
