Will The Dexter K23-532-533-00 Brakes Fit A #42 Spindle?  

Updated 03/20/2025 | Published 03/13/2025

Question:

Will this fit a 42 spindle? Mine uses the same bearings, but Im not sure about the spacing. I have hub 8-187. Do you offer a replacement?

Hello Pat, thanks for reaching out. The # K23-532-533-00 brakes you mentioned are for an 8K Hayes/AL-KO axle with a 4-bolt brake flange.

The # 42 spindles like part # TRU37FR are 7K rated and have a 5-bolt brake flange, so these parts would not be compatible.

I was not able to find any reference for the 8-187 hub you mentioned. What parts are you looking for exactly? If you are needing brakes for a # 42 spindle, those would be part # AKEBRK-7-SA.

Leave a reply below and let me know if you need anything else.

They are Old dexter hubs/drums. According to my dexter rep, older than his 25 years @ Dexter. I do have a # 42 spindle, but have the old 4 bolt flange, and Dexter says they are a 8k hub. I'm thinking the 8-218-9 hub will be what I'm going to use and looking into what backing disc and dust shield will work with them. Thanks again. Pat

@Pat So the etrailer Electric Trailer Brakes # AKEBRK-8 will work with the 8-218-9 hubs you mentioned. These backing plates have a 4-bolt flange. The bolt spacing is 3-7/16" horizontally, 3-5/8" vertically and 5" across diagonally. I would want you to check your brake flange and make sure this matches. All measurements are center on center.
