Question:

Will these fit any 15k axle? I want to take the air brakes off a trail-eze tandem dually trailer and replace them with these. Will that work ?

Expert Reply:

The Dexter Electric Brake Kit w/ Cast Backing - Self-Adjusting - 12-1/4" - Left/Right Hand - 15K # 23-446-447 will fit any 15K axle that have the standard 7 bolt mounting flange. These are self-adjusting brakes so there is no need for manual adjustments after the initial installation. They are labeled left-hand (driver's side) and right-hand (passenger's side) to ensure proper placement.

If you need the mounting hardware, I recommend # BRKH122510 for each axle. You will also need the wire # 12-2-1 and the rest of the wiring. I recommend the 7-Way Molded Trailer Plug with Junction Box # HS381-9000 along with ring terminals # 44-5310A. I also recommend loom clamps # A0500 to go with the Wire Loom, 1/2" Diameter (per Foot) # 459075-1 to protect and retain your wiring.

You will also need a brake controller like # 90195 for this application. I've linked the page to all your options, but this is a customer favorite.
