Sounds like you installed new brakes and they aren't wanting to grab and stop your trailer. Most likely you just need to adjust the assemblies so that they will actually grab. If they are self-adjusting brakes all you would need to do is make several brake applications with the trailer moving and they will set themselves.
To see how to manually adjust trailer brake assemblies check out the video I attached, fast-forward to the 4:35 mark of the video.
I also attached a help article on how to test brake magnets for you to check out as well.
