Trailer brakes, need hlep...

I was able to get all the parts needed and have replaced them. I was able to bleed the brakes with out much of an issue.
One quesiton, have any of you been able to lock up your trailer bakes while stop hard or quick? With the front tandems in the air, I can spin them just fine and aply preasure to the master cylinder and it locks up the brakes just fine. I sure there is no air in the system since I pump a lot of new fluid through the system. Once I connect it to the truck it stops fine and it feels like they are engaging but I can't get it to stop on a dime or attempt to lock up the trailer brakes, not sure if it should?
Thanks

I don't think you really want that. They are really supposed to assist you. Mine occasionally do lock up after they've been in the water and sitting and believe me, it's not fun when your trailer starts hopping with a boat on it.

Well that is good to hear. So I should be good then. I didn't think I wanted the the boat trailer to stop the truck but I was not sure how it should be reacting.
Thanks Dog.

The trailer with surge brakes can't stop the truck like you can with electric brakes. Surge brakes rely on the trailer pushing the truck to actuate the trailer brakes. If the brakes do lock, then you get into the brakes on-off trailer hopping situation. That's not good and suggests the brakes are too aggressive for the weight. You can see this on heavier car trailers with surge brakes. The brakes work horribly, hopping and locking, with the trailer empty, but work fine with it loaded.
