Info

Replace those old drum brakes with modern rear disc brakes. Included steel caliper brackets weld to your 3" tube rearend, making this a universal kit for a variety of applications. Basic kit includes caliper brackets for '69-'77 GM mid-size car front calipers, Pro-lite vented .810" x 11-3/4" iron rotors, steel brake hats (1.96" backspace), and rotor bolts.

Hat fits 5 on 4-1/2", 5 on 4-3/4" and 5 on 5" bolt circles.

Notes

Brake pad and caliper installation note:  

This bracket features a 90 degree bend in the bracket at the slider bolt threaded area for additional caliper support.  This part of the bracket may or may not interfere with the corner of the inner brake pad backing plate due to differences in brake pad manufacturers.  When this occurs, it will be necessary to simply remove a minimal amount of backing plate material at each corner of the inner brake pad to allow for the necessary clearance between the bracket and brake pad when the caliper and pads are fully installed.

  • Just about any classic vehicle’s drum brakes can be upgraded to the increased braking performance of a disc brake system. Our Buyer’s Guide provides an overview of disc brake benefits and what you need to succeed with your upgrade.
  • When it comes to a traditional style build on an early hot rod it just has to be rolling on a solid front axle of some sort. In this buyer's guide we take you through I-beam and round tube solid axles, spindle choices, radius rod needs, and more.
