Description

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 semi float axles with 8 lugs. This kit includes new studs, so you’ll need to select metric or standard studs when you order.

The kit includes:

  • (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) stainless steel 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 our mounting brackets are available separately here, and we can also provide longer braided stainless steel brake hoses here. To order this kit with the longer 18″ braided stainless, just order this kit with no hoses, and then add-on the 18″ hoses as a separate item.

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.
