Bigger tires mean i need better braking , so the word is to use 3/4 ton calipers and pads and the wheel cylinders use 3/4 ton or 1 ton ? so im thinking upgrading the master clyinder but wait i see bendix has a 28.6 mm & 40 mm now which is stock size cause i mite upgrade to the 40 mm and as far as the power brake goes thats the same as 1/2 , 3/4 ton so im good there as in wheel cylinders i see they have a 25 mm ? and rotors powerslots ? give me some ideas here

 

look into the monster caliper conversion, that will greatly increase your breaking, it is kinda expensive though.

The biggest killer of braking is heat. A slotted or drilled rotor is probably your best bet. I would also upgrade to reinforced or braided lines they do not allow expansion. The only true way to increase your braking potential is to have larger diameter rotors. Take a look at your newer trucks and performance cars. The rotors dwarf the ones on our Rams.
