[FC] Braking News

[Ken Hand]

     The original post said that the pedal got hard, not soft, after 
driving. Therefore the check that you suggested will do no good except 
show a good master cyl. if there is a dual master cylinder, as I see it.

     It was also said that the brake adjusters were backed all the way 
off, but were the linings still rubbing the drums? If so then the 
linings are swelling with heat and with no movement in the shoes the 
pedal will feel rock hard with no free play at all. The one thing you 
didn't say is if you have a dual master cylinder. Also after driving 
the 20 or so miles does the FC still stop OK other than the wheel 
locking? Did you rebuild the master cylinder?

Go down to your local auto parts store, and purchase a brass plug that
screws into the master cylinder where the brake line goes.  Then try 
the
pedal.  It should be rock hard.  If it isn't, then it is the master 
cylinder
bypassing internally.  If it is rock hard, then disconnect the rear 
line
 from the block, and try that half of the system.  If everything is 
good,
then disconect the front half and try the brakes in the rear.  You 
should be
able to find the problem using this method.  My personal guess is that 
the
linings are too far away from the drum face and need to be adjusted.  .
