'92 E-350, 7.3 IDI, flatbed dually, 60K, I would like to replace my present brake rotors, calipers, pads, brake line and brake fluid with heavy duty equipment. Can I replace the stock system with something bigger. I need more stopping power as I carry big loads and pull trailers..I do not exceed the maximum GVWR, but I need something more.. Presently they need replacing anyway. Could someone tell me if this is possible, and if so, where I can purchase these items online or parts warehouse..A couple places I went to could only supply stock replacement. Thanks..

I would go with ATE super blue brake fluid. Don't use any of the silicon stuff.

 

Try www.raybestos.com and look at their BruteStop or SuperStop line.
