Most people will put the brakes on the front axle of a tandem axle trailer or the front two axles of a triple axle trailer. This is what I recommend doing if you are not wanting to install brakes on all of the axles.

For the most effective braking system though, I recommend using brakes on all 3 of your axles. This will help your brakes last longer because they won't be working as hard individually and it will help give you better braking performance.

I have attached a link to our selection of trailer hub and drum assemblies as well as our brake assemblies to look through. If you could let me know what your axle capacity is and I can make some recommendations for you.
