Hello Caden, thanks for reaching out. AL-KO was bought out by Dexter quite a while ago, and many of the old AL-KO brakes use a bolt pattern that is now obsolete. The current standard 4-bolt brake flange is different, and I have included those dimensions for you below.

If your brake flange does not match this, I am afraid you will be out of luck for the brakes. The only option would be to replace the axles with something more current that uses a standard 4-bolt brake flange.

Hey Caden, did you find a solution for your trailer's brake assembly issue? I'm asking because it could help others facing similar challenges with older AL-KO axles.

@JesseM I found out exactly what you said. At some point I will have to replace the axles as there not making any parts for it. Luckily I did find correct brake pads and springs left over at a trailer store.
