How much bigger is the 1 ton brake pad then the stock GM pads? A common upgrade has Been the 80 MM GM caliper. We bought our first GMC in 2003. At every GMCMI event since. The talk has been that the original brakes left something to be desired. My thought was that. How did GM get the GMC out to the public with brakes that lacked performance in the area of braking. The problem has been how self adjusting rear drum brakes function. To self adjust properly. You have to have brisk braking in reverse. We never do that. Thus the adjuster can't do the job. So for 13 years. I jacked up the rear axles once a year to adjust the rear brakes manually. I tow all the time in the range of 17,to 24,000 GVW. Live in the flat Midwest. Been very happy with the braking of all 6 wheels. Even when we have been out West. But. To get the best braking from the original braking system. YOU MUST adjust those rear brakes once a year. Two years ago. I decided to reduce my adjusting by 50%. I installed Disc on the front rear axle only. Braking is improved. Have Quad bags with the rear disc. No reaction arm, or true track. Haven't experienced rear/rear lockup. Adjust the rears properly. Or add the rear disc first. Before trying to add more braking to the front. The front is already doing the most. Bob Dunahugh
