[FC] E- brake plus master cylinders

[James Davis]

The brake petal getting higher after the first pump is a sign that the 
shoes are not returning to the pin.  In other words you brake springs 
are weak.  That is not uncommon as the heat of the drums will take 
temper the springs over some time.  I use the heaver springs from 
<http://musclecarbrakes.com/>.  They sell their trick springs separate 
from the stage III kit.  I highly recommend their drums but they are 
very expensive.  I have the dual MC kit from the Source.  It has been on 
the Rampside for 11 years with no problems.

I have a brake line failure in the not so recent past on a 61 coupe so I do realize that a properly functioning e-brake is very important.  I try to be vigilant about the braking system.  Last summer I rebuilt the original Delco master cylinder, replaced all the wheel cylinders, the front drums, shoes, hardware, lines, and hoses on this van.  I've known that the E brake has needed attention since then.  I tried to adjust it after getting some miles on it all, and still can't get adjustment.  at the rear of the front cable.  Seems like a good time to do it now since the accelerator cable is broken.

However I have noticed that the pedal comes up a little bit further if I press the brake, release, then press it again.  Still not spongy, just a bit higher.  Seems like I remember that this in normal, but seeing how my e-brake isn't functional, paranoia has set in. Why does it do this and is it indeed normal?
