Description
Converting the drum brakes on your 14-bolt rear axle to disc brakes has a lot of benefits:
- Improved braking performance
- Easier brake maintenance
- Increased resistance to brake fade
- Reduced unsprung weight on the rear axle for a better ride
- Improved brake pedal feel
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.
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.
We include a parts list with instructions in the kit so that you can order replacement parts locally if you want.

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.

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…

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!

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.
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.

My application is a 1989 V2500 Suburban. I use the truck for towing a fairly heavy trailer, and this rear disc conversion is really helpful. It provides MUCH more stopping power when towing. It’s pretty sweet just driving around town also. I would give it 5 stars. A couple of tips I would have benifited from: 1) If you cut the brake lines as I had to, then you better spend some money for a high quality flaring tool. Cheap ones will not give the perfect flare needed for 1500PSI brakes. 2) Clean the back side of the axle where the new brake rotor will contact it. Clean it really good. 3) Don’t use your shop press to press in the new studs that capture the rotor to the axle. I tried that first and ended up with .070 runout (wobble) in the rotors. Best way was to draw the rotor into position on the axle using lugnuts on the studs. You can tighten in a “star pattern” and keep the rotor straight while pulling it onto the axle. Using this approach, I ended up with .007 runout. 4) The E-brake cables offered by Lugnut are well worth the money. If you are like me, you’ll end up ordering them when you find out how crappy your stock cables work with the E-brake calipers.
