i wouldn't bother the benefits wouldn't outweigh the costs i don't think. I used to work on Chevy service trucks for a local county and i hated working on the brake system on those. Just would always end up being a pain in the a**.
I'm with Pro on this one just step up to a Cobra kit. Heck even step up to PBR dual piston thats a big improvement over stock by a good bit.
