Brakes

["Charles E. Whitney" <clncrew@ziplink.net>]

Hello All

I have a brake problem.  No pressure, my foor goes to the floor before 
any braking starts.  I do stop, but ahhh... I am nervous.

There are no leaks in the system.  I've actually had the problem for 
several months and there is no sign of leakage at the calipers in front, 
or the cylinders in back.  I have a '67 square.  

I figured it was the master cylinder, so I replaced it, bled the brakes, 
naturally front and back.  Still I have the problem.

I can build up pretty good pressure after pumping the brake 20 times.

Brake pads and shoes are in great shape, since I replaced them too.  
Rears shoes are adjusted properly.

Any hints?

I don't see the brake lines bulging anywhere.  I've had the car 6 months 
and am guessing the lines are original.  Could it be they expand enough 
to make me loose pressure, but not enough to see?

Any help would be appreciated
