i do not care for any rear disc kit that has the e-brake in the caliper....to complicated and a chance for things to seize up. much better to have a drum brake e-brake that is housed behind the brake rotor. 87-88 daytonas had the former style and it was very problematic. 1989 and newer dodge fwd's (and neon's) with rear disc had the later/better style that is problem free and much easier to work on.

remember that a drum shoe has a larger swept area than a disc pad and so works great holding a vehicle still and the shoes only need to be replaced due to extreme age when the linings fall off the metal part. i'd prefer to use a factory rear disc brake package from the same manufacture (GM in this case) so that parts are easy to get. i bet a lot of aftermarket brake kits use their own pads and parts, etc so not easy to just go down to the local store. i want to put 3/4 ton 2000+ rear disc on the back of my 72 burb 2wd 8 lug. if i too much money, i'd swap out the 10.5 FF 14 bolt axle for a 2000+ 11.5 FF axle.....that would totally killer.
