4- piston caliper "sleeving"?????

I use a Motive Power Bleeder to pressure bleed the brakes. Its gets me a nice high and tight brake pedal:

Another thing those 4 pistons set ups like is 7/8" rear wheel cylinders along with a proportioning valve. I ordered rear wheel cylinders for a '72 D100 Dodge truck and they bolted right on.
