Recommended 12 x 2 Inch Brakes for Older Flying L Gooseneck Horse Trailer w/ 4 Bolt Mounting Flange

Question

Question:

I am doing a project for my boss and I have a few questions. I will start with the project, its an older Flying L gooseneck horse trailer with tandum axle, and it has the old 4 bolt axle mounting flange with bolt measurements left to right top 2 holes measure 3inches, the bottom 2 holes from left to right measure 2.5inches and center of top hole to bottom hole measures 3 1/4 inches . It requires a 12x2 inch electric braking assembly. Now do all 12x2 brakes fit the 4 bolt mounting flange or does it have to be a special brand or part to bolt up correctly. I am also in search of hubs with a 6 bolt pattern. any help or advise would be great. thank you very much.

When it comes to brakes for your boss's older Flying L gooseneck horse trailer, I believe that I have exactly what you are looking for, # 23-105-09 and # 23-106-09 for a 6,000 lb axle. I have included a picture which includes the mounting hole measurements for these brakes. Although these measurements are very close to those that you have provided, I recommend measuring one more time to ensure that they will work for you.

As for hubs with a 6 on 5-1/2 bolt pattern, you can use Trailer Hub and Drum Assembly, # AKHD-655-6-K, as long as the trailer uses inner bearing # 25580 and outer bearing # 15123.

If the trailer does indeed use these bearings and you would like to replace those as well, take a look at Bearing Kit, # BK3-110.

The #23-105-09 would work well since the dimensions and bolt pattern are correct for your Hayes 7k setup. Typically brake assemblies in this size will have weight ratings that range from 5,200 up to 7k so the #23-105-09 will work well as they match…

Answer 6

Most likely the #23-105-09 and #23-106-09 would work well for you, but you need to verify one more thing. Does the current brake assembly you have attach to the axle with 5 nuts? If so, then you have the standard bolt mounting pattern these two would…
