Converting the rear drum brakes on your 1962-1972 Eaton axle over 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.
This Eaton axle drum brake conversion kit is for axles offered from 1962 to 1972. In 1973, GM stopped using the Eaton axle and switched over to the “corporate” 14 bolt axle.
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) 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.
