[Healeys] Brake Problems Continue

[WILLYS49 at aol.com]

I still cannot get brake pressure on my '59 100-6. I have replaced just 
about everything (mc, wheel cylinders, brake shoes, all hoses and rear brake 
lines. I do have a few clues that might help. Before I replaced the rear brake 
lines and hose, I pinched off the old brake hose and felt pressure on brake 
peddle. After I replaced rear hose and the two rear brake lines that I 
thought might be leaking, I bled all the air out of lines. Still no luck. Peddle 
immediately goes to floor. Takes about three pumps to feel pressure and 
holds but immediately goes to floor with no pressure when released.

I know that the new rear brake shoes are about half the thickness of the 
originals and the adjustment cam doesn't seem provide much resistance on drum. 
If the brake drums are worn and shoes are thin, could that be the cause of 
problem? I'm running out of ideas and parts to replace (not to mention 
summer is coming to an end). 

Any thoughts or advice appreciated.
