<VV> Brakes grabbing

[Dennis Pleau]

1. Miss-match of shoes on the front?
2. 500 mile shoes haven't bedded completely yet?
3. Reversal of the primary and secondary shoe somewhere?

I'm sure others will also have ideas.

I put the Monza up in the air to work on a couple of items.  The  
major item is the brake problem.  The history on the brakes is: all  
of the shoes have about 5 thousand miles on them except for the front  
drivers that was replaced about 500 miles ago due to a leaking wheel  
cylinder that was messed up by a rookie mechanic (that would be me -  
I now know not to apply the brakes before reinstalling the drums).   
Except for the master cylinder conversion, turning of the drums, the  
overhaul of all but the driver's side wheel cylinder and installation  
of the rear shoes, all of the work has been done by me.  The other  
work was done by a club member.  All of the wheel cylinders have been  
overhauled, and as far as I know at this moment, are not leaking (I  
may learn different when I take off the drums, but I really don't  
suspect this as the cause).  The drums were turned (on advise before  
I knew better).  The master has been changed to a dual cylinder and  
yes, it was bench bled.  There has been no loss of fluid from the  
reservoir.  The fluid was bled and changed to DOT 4 about 500 miles  
ago.  All of the hoses have been replaced 5000 miles ago in front,  
and 500 miles ago in the rear.  The symptoms are : The rear drivers  
wheel rolls free from 9-3 o'clock as observed on the valve stem and  
has drag from 3-9, the rear passenger is free from 6-11 and drags  
hard from 11-6, the front drivers is free from 7-12 and drags very  
slightly from 12-7, and the front passenger is free from 7-11 and  
drags slightly from 11-7.  I haven't removed the tires and drums  
yet.  What could be the cause and what should I be looking for when I  
remove the drums?
