My jeep has been sitting for 15-20 years, therefore I will diffidently need to be rebuilding the brake system. I have been considering while rebuilding the brakes maybe I could upgrade to disk brakes. I have done some preliminary research but I don't see much of information on a conversion. KW has the conversion kits but those don't look cost effective. I know some members have upgraded their brakes but I cannot find 3B specific information. I would appreciate any input on the subject or lessons learned. One of my dilemmas is: is it worth it or should I just keep the jeep original? This may become more clear after I tear down the brakes and inspect the condition of all the brake parts. Second, question is has any one upgraded to a dual reservoir master cylinder? An additional question if these are original steel lines should I replace them. Any brake system thought or suggestions?! BRAKES ARE KINDA IMPORTANT!
