Brake problems...
 

MY NEIGHBOR HAS A 68-GMC THAT HE HIS WORKING ON FOR A CUSTOMER, AND IT HAS NEW WHEEL CYLINDERS ALL THE WAY AROUND, NO LEAKS, BUT HE HAS WENT THROUGH 6 MASTER CYLINDERS, NEW FROM THE PARTS HOUSE, BENCH BLED THEM ALL PRIOR TO INSTALLATION, AND I HELPED HIM BLEED THEM AFTER THEY WERE PUT ON. STILL GOES ALMOST TO THE FLOOR ONCE BLED. WE FIGURE THE MASTER CYLINDER IS ALL IT CAN BE, BUT GETTING 6 BAD ONES? WE WOULD REALLY APPRECIATE ANY FEEDBACK ON THIS FROM YOU GUYS.

THANKS,

Are you getting good fluid at each corner with no air in the lines?
Are the shoes adjusted out enough?

I have just had the very same problem, it would lock up the brakes but the pedal was allmost on the floor, It turned out that i had been sent the wrong bore inside the master cylnder,
