Converting the drum brakes on your 14 bolt 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 in your old pickup to disc, or adding disc brakes to an axle that’s going in a custom buggy, we’ve got you covered.

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: 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.

This 14 bolt axle drum brake conversion kit is for full float axles with a slide-on drum. Beginning in 1988, a “slide-on” style of drum was offered on the 14 bolt axle. This was considered an upgrade over the older stud-mounted drum design.

However, some vehicles were produced with the older “stud mounted” style of drum after 1988. In fact, both stud mounted and slide-on drums can be found on vehicles as new as 1999.

Since both slide-on and stud mounted drums can be found on late 80’s and 90’s model trucks, be sure to check your axles against our identification chart. (Also, our kit for stud mounted drum 14 bolt full float axles is here).

NOTE: This kit requires 16″ or larger wheels if you choose slide on rotors.

The kit includes:

  • (2) GM 12.5″ standard 3/4 ton truck rotors (these slide on outside the hub like factory drums)
  • (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, which can optionally be upgraded to braided stainless steel
  • All bolts are Grade 8, much stronger than the standard Grade 5 you find in most kits

Please note that while mounting brackets are included in all our brake kits, our brackets are also sold individually here, and we can also provide longer braided stainless steel brake hoses here. To order this kit with the longer 24″ braided stainless, just order this kit with no hoses, and then add-on the 24″ hoses as a separate item.

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.

Kit includes instruction sheet and part number list, so that ordering replacement parts is easy. 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.

    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!

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

  3. alexander.epishin100 (verified owner)

    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.
