I'm trying to learn the difference between the 7500 and 8800 GVW front brake pads on 2500 2wds since both of ours (96 and 99) are 8800 GVW trucks. I see differences in some parts of the steering linkage, but I can't find what's different about the front pads. Are they simply 3500 units?? Thanks.

 

Looking at CAD drawings of the various brakes, I don't see a difference between the 2500's (8800) and the std. 3500 pads. I do see a difference in the 2500's 7500 and 8800 inner pads, though. The 7500 backing plates have 2 'ears' that locate it in the caliper while the 8800's have one solid plate in place of the 2 smaller ears. It sure looks stronger, but is that all?

 

I barelymanaged to get a set of 7500 calipers and new pads on my 8800. It was a royal pita that turned into a 4hr job. There may not be much noticeable diff but the inner spacing from caliper-to-pad-to- rotor is wider for a 8800 vs 7500. I know that if I had new rotors also, I would not be able to install the 7500 calipers, there's not enough room when fully compressed and new pads to slide it over the rotor for install. I thought the problem was faulty pads or calipers....lol. With new stainless lines the thing sure does stop good but I will be changing it out to the correct caliper. Hope this helps some one in the future.

 

On my 2001 they are the same parts as the 1 ton.

 

Yea...I guess it could be possible. I can't return them but once these pads wear out I'm going to have to order the correct caliper as I won't be able to reinstall w/new pads....they just won't fit over the rotors.
