Drum brake standstill

[PAscout800]

Hey everyone.

Got the engine running and carb rebuilt, now on to the brakes.

I bled the master cylinder (still a little soft but had resistance). Reinstalled the brake lines. Started with passenger rear. No bleeding. Took out bleeder screw, cleaned the passage well, still no bleeding. Same with driver rear and front two.

At what point do I just all new hard lines and rubber hoses? After I try to vacuum bleed? Replace brake cylinder first? Try to chase it to maybe a clogged portion of the hose?

Does it have a combination valve with brake warning shuttle valve?

Start undoing lines 1 at a time starting between the master, and the combo valve, then gravity bleed it to every connection point after that. 50 year old rubber hoses should always be replaced. Cheap insurance.

Heck even removing hard lines and using compress air to make sure the line is clear is a good idea when you are dealing with unknown condition lines.

Vacuum bleeding from the wheel cylinder usually is not great as the bleeders leak air. I have never gotten a good bleed with a mighty vac.

Pressure bleeding from the master is much better.

Rent a human helper is also a great idea.

However you should 100% be able to gravity bleed everything before moving on to pressure bleeding.

Good feedback and I appreciate that. I just ordered all new rubber hoses and also the little hardlines up front.

I’ll take your advice on bleeding, as I have read on reviews the vacuum bleeders aren’t the best but still kind of work. Thanks again!
