Has anyone had their brakes lock up after do a complete bleed job from Hydro.. to brake cylinders. Starting with Hydrovac #1 bleeder (rear one) then #2 (front one) then going to the nearest wheel cylinder and on thru to the furtherest. Just can seem to get all the air out of the system or what. Master cylinder is NOS, flex lines are new, have flushed out all lines completely. Have honed out all wheel cylinders and replaced the rubber (which most auto parts store carries the 11/2 and the 11/4 rubber). If someone can please help I would be grateful and maybe even let you drive my 1944 CCKW 353 Tipper! Thanks, Drew

with the lines being to small....the brake lock up should solve itself after a few minutes.
take a look through the refill cap of the mastercylinder and gently apply the brakes. there are 2 holes in the bottem. A small one and a larger one.... make sure that when you release the brake pedal the small hole is completely open. (If you cant see this feel with a needle)
If it is covered up adjust the link between pedal and cylinder to see if you can get it open. if not, the cylinder is not good....either is the rubber cup soluted or the parts are not mounted correct.

good luck
