I can help you find the right assemblies, but I do not know exactly which ones you have on your trailer. I looked up your Keystone Alpine 3640RL and it appears to be rated for around 15k and has a tandem axle setup so you'll most likely need higher rated assemblies.

To pick out the correct brake assemblies for your trailer you need to know a few things.

You will want to measure the inner diameter of your hub/drums and the depth of the drums to determine what brake assembly dimensions you need. For example the part # AKEBRK-8 is a 12-1/4 by 3-3/8 inch brake assembly set.

You also want to determine what the bolt pattern is of your assembly mounting flange. The standard size is 4 on 4 inch. You also want to determine the axle capacity of your trailer and go with an assembly that has the same rating, the # AKEBRK-8 has an 8,00 lb capacity.
