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.

The DBK9TRK 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. MBM’s 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”, 3-1/2”x 2-3/8”, 3-9/16” x 2”). Top that off with 5 on 5 1/2 bolt pattern rotors and you eliminate much of the customer guess-work when purchasing and installing the kit.
