I'm in the process of swapping a ff 14 bolt axle out of a 2004 2500hd. My truck currently has the weak 10 bolt axle with drum brakes. My question is, will I have a problem with my brakes because the 14 bolt has disk brakes? There are aftermarket kits for the 10 bolt axle to convert it to disk and in these kits it doesn't say anything about needing a special master cylinder or proportioning valve. I'm also unsure how the brakes are praportioned on my truck. I haven't found any prop valves on it.
