My friend pickep up a 1949 chevy styline deluxe, with no brakes. We installed new wheel cylinders, shoes, springs, master cylinder and lines. We tried bleeding the brake system and fluid comes out from the small hole on the fillerplug (when we pump the brake pedal). Is there any special way in bleeding this brakes? thanks
I can't imagine doing one of these is too much different than doing any other hydraulic system. I would move to the furthest wheel from the m/c (usually pass side rear) and put a piece of tubing over the bleeder valve nipple and put the other end into a jar with some clean fluid in it. (pick up a few feet of something like 1/8 or 3/16 vacuum hose at the auto parts store) Open the bleeder slightly and have someone slowly pump the pedal. Watch the bubbles coming out in the jar. When they stop and fluid begins to flow, close the valve and move to the next wheel cylinder and repeat.
Keep filling up the m/c so it doesn't run low on fluid and suck air. Do this to all four wheels and see if you are getting pedal. By the forth wheel you should have a somewhat firm pedal, and might have to go through all four wheels again to get all the air out.
For some reason a certain percentage of brakes are a bear to bleed, and some are easy. But if there are no leaks and the components are new the system will eventually bleed out.

That's exactly what I did, but when i pump the brake pedal brake fluid comes out from the small hole on the filler plug. Even when I benched bleed the new M/C, fluid would come out from the small hole at the filler plug instead of the line hook up. Thanks I'll try again tomorrow.
