Brian0006 Yes! Disc brakes make a huge improvement in stopping. While the front brakes get the load in a stop and are the most important for upgrade, the rear could use disc brakes as well. Someone else with a greater knowledge on this subject will chime in I'm sure. The cost is higher but if you check on what other Chevy vehicles rear disc brakes will match your rear setup and buy them used, the cost can be reduced quite a bit.
