Replacement Master Cylinder for a Model 10 or 20 Brake Actuator

Question:

see attached pictures. there are no model numbers on my master cylinder. it looks a lot like Item # DX66FR the trailer has drum brakes. also, how would I determine if I need the whole assembly or just the master cylinder? thanks

I agree that the master cylinder in your pictures is for a Model 10 or 20 actuator so # DX66FR is the correct replacement. If the springs and hardware are in good shape operate properly then you would not have to replace the whole assembly. If they are not in good shape/operating properly then you will need # T2374600. If it were me this is the route I would take to ensure all the parts are new and in good working order.
