Need Azusa Wheel disc brake/caliber

[Longtrip]

Does anyone know the manufacturer of the disk brakes for 5.00-5 Azusa wheels that were listed in the 2017 GREAT PLAINS Aircraft Supply catalog on page 53. Picture attached. The Azusa site doesn’t list them. OR I’m looking for a set 5.00X5 wheels and disc brakes. I have Aerovee brakes now which are marginal.

Azusa doesn't have them?

I couldn’t find them on their website.

I used the Azusa 6" wheels and Hyd brakes from Great Plains on the SSSC for about 8 years. Great little brakes and I used Cessna 150/172 master cylinders for the toe brakes with a change of O-rings to match the O-ring in the brake caliber. Brake instructions said to use auto transmission fluid.
When I went to a larger taller tire than the 600x 6, the braking was a little less, but very usable.
Picture of the GP brakes and the larger taller tires than the 600x6 tires.
With the larger tires I use Matco brakes for a little more braking. Using off field most of the time I needed good brakes to taxi with the tail up level and work the main wheels around rocks and holes, etc.
I heard somewhere that they are Go-Cart brakes. I don't know for sure.
