Description

Converting the drum brakes on your 14 bolt rear axle to disc brakes has a lot of benefits:

  • Improved braking performance
  • Increased resistance to brake fade
  • Reduced un-sprung weight on the rear axle for a better ride
  • More clearance for wheels
  • Improved brake pedal feel
  • Easier brake maintenance

Whether you’re upgrading the drum brakes on your old pickup’s rear axle, or adding disc brakes to 14 bolt axle for a project vehicle, we’ve got you covered. And you’ll love your 14 bolt disc brake setup when the project’s done.

Every Lugnut4x4 disc brake conversion kit includes all the parts you need to convert your drum brakes to disc. All you need are the appropriate tools, brake fluid, and a little elbow grease.

NOTE: This kit is not for dually axles. Not sure if you have a full-float or semi-float 14 bolt axle? Not sure if you have a slide-on drum or not? No problem! Check out our 14 bolt identification chart and you’ll know exactly what you need.

Our 14 bolt kits include:

  • (2) GM 12.5″ standard 3/4 ton truck rotors
  • (2) 3/8″ thick laser cut brackets
  • (2) GM standard duty JB6 3/4 ton truck brake calipers with steel pistons. Heavy-duty JB7 caliper upgrades are available.
  • (2) caliper pins
  • (1) set of four high quality semi-metallic brake pads. Ceramic brake pads are available as an upgrade.
  • (4) copper washers
  • (2) banjo bolts
  • (2) new inner hub/wheel seals
  • Anti-rattle clips
  • (2) flexible brake hoses are included (braided stainless steel hoses available)
  • All bolts are Grade 8, much stronger than the standard Grade 5 you find in most kits

Please note: You can buy our 14 bolt disc brake mounting brackets as part of this kit, or you can buy the brackets by themselves here.

Also, if you need a 24″ braided stainless steel brake hose, we do not offer them with this kit. Instead, order this 14 bolt disc brake conversion kit without brake hoses, and then add the 24″ stainless steel hoses here.

Lift kits and hoses: Remember, the brake lines connect the caliper to the hard line on the axle. Since the hose does not go from the caliper to the frame, the amount of lift does not matter.

Interested in adding an emergency brake? If so, we offer calipers with integrated emergency brakes (just select that option above). This will give you a manual e-brake that hooks up to your cables.

14 Bolt Disc Brake Conversion Kit Installation

Anyone with a basic understanding of brake systems will find the installation simple. Our only bit of advice: The rotor goes on the backside of the hub.

Also, we include and instruction sheet and a part number list in the kit. That makes ordering replacement parts easy.

    This kit fits just perfect. Really easy to install. And looks nice on the axle. Lugnut 4×4 is the real deal and fast response to email and shipping time. Thanks for your great service.

  2. strechboshers

    If you have the gen.2 14bolt axle with slide on drums its a perfect match. Did the swap on a late 90s 2500 Suburban 4×4 daily driver and I cant be any happier about the fit, the ride, and the stopping power increase. An absolute must! Great product! Great company!

  3. robholtz

    Did a swap on a 1994 2500 suburban and made a big difference with stopping power, great kit to upgrade the rear drums…

  4. travismgilmore

    Great kit. Easy install, everything fit very well, quality parts, and fast shipping. Kit is cheaper than anything I could find including piecing it together myself. Money well spent!

  5. Chris S.

    Great kit. Brackets are good quality. I did my research and this kit is the most inexpensive way to put disc brakes on a 14bff.

  6. Nancy Randall

    Hello dear friends. Many thanks for your work and the set of rear brakes provided for my Suburban 2500. I want you to know that now this set works and pleases its owner, that is, me on the other side of the planet earth. Thank you very much.
