I have a 1996 K1500 with classic brake problems. Drum on the rear. I love the truck but it will not stop with a load behind it. I have read that 2500 calipers and pads can be installed for more braking power on the front. What is involved on doing this conversion? Is it possible to replace the rear differential with one with disc brakes from a later K series or a Tahoe. I know the Tahoes have coil springs, I could cut the pads off my original housing and weld them to the Tahoe housing. One reason I'm considering replacing the complete unit is mine has over 400k on it and it is not limited slip. I would like to replace it with a G80 code unit with disc brakes. Has anyone done this? Is there an issue with the park brake cables? Also considering replacing the MC with a 2002 with the larger pistons. I know there are aftermarket brake kits but it would be easier or me to replace the entire unit if the modifications aren't too extensive.
