Wish you had 4 wheel disc brakes and don't want to swap your rear end to do it? This kit is what you want to convert your PRE 1987 Ford truck or Bronco rear drum brakes. Easy to bolt on and comes complete with large single piston calipers and emergency brake cables all in this one kit! When converting to 4 wheel disc brakes you will need a disc/disc proportioning valve and larger bore master cylinder to get the right ratio and fluid to those rear calipers.

This kit provides an easy to install, bolt-on solution for upgrading your Pre-1987 Ford 9" rear-end light truck to disc brake performance. Many consumers may be unsure of which size 9" rear-end their vehicle has. Our kit is unique in that it provides all the brackets and flanges that fit the three most popular sizes of the 9" rear end (3-3/8" x 2" Small Ford Style, 3-1/2" x 2-3/8" Big Ford Old Style, & 3-9/16" x 2" Big Ford New Style). Top that off with 5 on 5-1/2" bolt circle pattern rotors and you eliminate much of the customer guess-work when purchasing and installing the kit.
