Correct Replacement Braking Assemblies for an Older Hayes AL-KO 12K Axle
Question:
Hello. I Have an HD tandem trailer axle setup. After hours of research I found that they are 12 ton Hayes axles pre 1988 with dual round brake magnets. The shoes are 3.5” wide . the Stud pattern is 8 x 6.5” , enter hub is 4.750” inside diameter of drum where the shoes ride is 12.25”. The outer wheel bearing is 25580 and inner wheel bearing is 28580. The oil seal is 27438 The backing plate has 6 bolt holes that are equally spaced. Is there a conversion kit that you sell that can reuse the axles that are already installed? Appreciate all replies. Respectfully.

I am assuming you're looking for a replacement braking assembly for your older Hayes AL-KO axle. If so, you're going to just need the Hayes/AL-KO Hydraulic Brake Kit - Duo Servo - 12-1/4" # K23-524-00-2 or just # K23-524-00 for one assembly.
You mention that you have a 6-bolt mounting flange, and while it's true the older Hayes axles had 6-bolt flanges it only actually used 5 to mount.
If you're also needing replacement inner/outer bearings as well as an oil seal, you can use # 28580 for the inner, # 25580 for the outer, and # 91030 for the oil seal.
If you're needing something different, feel free to let us know and we'd be happy to help.
