I did the front upgrade first with the EGR and left the drums on the rear and I feel that the braking was worse than stock......they just made the truck stop pulling to either side when braking. This was the full kit with the rotors, calipers, pads, etc. I swaped to discs in the back......no help there. The price has come down since then but here I am about $1800 in new brakes and they worked worse than stock. It was amazing that when I took care of the proportioning valve issue, everything seemed to come together. Performance with never be the same as a newer Dodge or Chevy though. The thing is, I drove the truck with the front brakes doing all the work for so long that the front pads have worn prematurely and I'm not paying the $170+ for the replacements from EGR. Would you???
