Brake Question??

[mreid]

I want to change my brake fluid in my '82 300sd but I can not get the fluid from the front resevoir. I used a turkey baster to suck out the back compartment so I could start bleeding with new fluid but be darned if I can figure how to get the fluid from the other chamber as it appears to be sealed from the other and the filler hole except for a small vent hole at the top.
HELP!!!
