How to upgrade brakes on 2000 Chevy K3500 DRW.

Put brakes on the trailer. I used to go thru brakes every 15K with an 89 1 ton before putting brakes on the 3500 SA trailer I had. I then went to over 30K on the front brakes!

Otherwise, yeah, go to a different brake setup int he front. Or do something to the rear drums to make them more aggressive. I would get 15-25K out of the fronts, 125K out of the drums with 8 lug rigs from 81-96 I have had doing what you are doing with an auto. 50K out of the fronts with a manual.
