Thanks all for the information. One more question. POL or CPP for parts? POL lists their master cylinder as 7" CPP at 8", if there truly is a 1" difference POL would be the way to go as it is tight under the truck as we all know. I haven't completely decided yet but I figure if i'm buying and replacing everything but the rear brakes whats a little extra installation time as the cost difference is only $200 to go with the power master.
