Disc Brake Assemblies For Changing A 12,000LB Dexter Axle To Hydraulic Disc Brakes
Question:
Will these assemblies fit a 12000 pound dexter axle? If not, do you have a product that will? I want to change from electric drum to electric over hydraulic disc. Thanks

We have the Kodiak Disc Brake Kit # K2R1258L12 that is designed to fit your 12,000lb Dexter axle. You will need to ensure that you have the Standard Duty 12,000lb axle as this kit will not fit if its a Heavy Duty 12,000lb axle. If you need help determining which you have please let me know your axle serial number that is on the information sticker for the axle or can also be found stamped in the axle tube on the rear of the axle on the passenger side.
The Kodiak Disc Brake Kit # K2HR12A11-120DW is for 12,000lb ALKO axles only.
With the axle serial number I can also ensure that the Dexter Trailer Idler Hub Assembly # 8-214-8UC1 will replace your current hub/drum. This hub uses Bearings # 3984 (2.625" inner diameter), # 28682 (2.25" inner diameter), and an oil seal # 10-56 (inner diameter 3.125").
You will also need a Dexter DX Series Electric Over Hydraulic Brake Actuator # K71-651 and hydraulic line set. If you can let me know the distance from your axle(or axles?) to the location the Actuator will be installed I can recommend a set of lines.
