i recently purchased an 03 RCSB that had been totaled but had a very hot motor/TC/tranny/exhaust etc... it also has rear disc brakes... mine doesnt... how do you convert??? remember the wrecked truck has no rear end gears and the axles are a little bent...

 

Do you plan on upgrading the rear rotor/caliper setup or running stock?
are your front brakes stock?

 

just take the axles out of both trucks so you can the backing plates and everything off. then swap it all over! you dont need to do a proportioning valve or anything....

 

yes im gonna stay with factory rear discs for now money is running low for now... yes my fronts are disc. and i cant use the axles on the other truck...

 

You don't need to swap the axles, just remove them to gain access to the backing plates that you'll need for the disc setup
