Dexter Axle D35 drivers side brake part number?

[52fordredbelly]

Hello all (and thanks in advance). I found great information searching through the forum on where to find accurate axle numbers for my Dexter axle opposed to working off of the axles sticker alone. Unfortunately I haven't had luck so far searching for how to ensure I locate the correct part number for a drivers side brake assembly (2010 Jayflight 26BH) It is not operating properly and is "over-engaging" which is overheating the rim, brake, tire etc. I have checked everything, reset adjusted brakes and no matter what, it is the only brake on the rig which continues to gives me this issue. At this point seems the easiest / best solution is to just replace the whole assembly, adjust it and get out on the open road.

Axle info D35 (Dex# on sticker 48740) stamped into the axle just under "Dexter Axle" is 123586120.

Any help in identifying a resource to ensure i'm getting the correct assembly is much appreciated.
