Eaton H052/72 Axle Disc Brake Conversion Kit

Our disc brake conversion kits are the best conversion to eliminate drum brakes, in many cases it is less expensive to switch to disc brakes than to rebuild drum brakes. Changing from drum brakes to disc brakes is easy, and all the parts you need to complete the conversion and get rid of those heavy drum brakes are included in this kit. In the end you will have an axle that stops better, is easier to maintain, and weighs a lot less.

The brackets in this kit are something we have had for a long time, the 14 Bolt bracket, I was simply unaware of the fact that they work on the Eaton Axles from '65-'72. The Eaton axle was the axle GM used before the Corporate 14 Bolt was developed and they can also take a beating.


  • Requires single steel wheel 15" with a maximum 4" back spacing or larger aluminum wheels

Complete Kit Includes:

  • 1 Pair Eaton H052/72 Axle Disc Brake Brackets
  • 2 Weld on Brake Line Tabs
  • 2 Brake Line Clips
  • 2 Brake Calipers
  • 2 Hydraulic Hoses with 10mm Banjo Bolt Fittings (Your hard line requires a 3/8-24" inverted flare fitting for these hoses to bolt to)
  • 4 New Brake Pads
  • 2 New Rotors


  • Rotor installs onto the backside of the hub!
  • This kit does not work on axles with slip on drums, drums must be mounted on the backside of the wheel hub
  • Axles older than 1971 will need the studs changed out to the 1971-98 studs. This requires drilling your 70 and older hubs to accept the larger knurl diameter or switching to a newer hub
  • 1973 factory studs generally work but if longer studs are needed, usually dually studs are long enough. Here is a list of the many different studs that were made for these housings: Dorman Double check stud diameter, studs should drop freely into the rotor. DO NOT press studs into the rotor. If your hub has too large of studs you will need to drill the rotors to accept them. Be sure to have minimum 5/8" lug nut thread engagement once the wheel is installed
  • Don't forget to re-bleed your brakes once you've installed your new conversion kit.
  • A Proportioning Valve is recommended, this will allow you to fine tune your front/rear stopping power bias. Your front axle should always do about 70% of the work.

Eaton HO52 disk brake conversion
Derek Doyle (California) | March 26th, 2023
Kit worked perfectly for my 72 Chevy C20 with an Eaton HO52. When I got the truck the rear brakes were soaked from leaking wheel cylinders. This kit was cheaper than buying all the new parts to fix my drums. I've been driving it for a couple weeks now and all is good. Installation was easy enough to install!!

Great Product!!!

What an awesome package, all the proper parts in one package. I can't wait to get it installed. Ordering was a breeze, shipping was fast. This is (in my honest opinion) a must-have upgrade for an old Eaton rear end. Thank you Ruffstuff folks for putting this together.
