Surge brakes

[CatFan]

I replaced my actuator and bled the brakes and still get what I consider excessive slam when even slowly pulling away from a stop. I also have a hitch clamp making the hitch itself solid as a rock. Must be the nature of the beast.

You can’t get rid of it all. If the trailer brakes are on when you stop, they are on when you just start to pull away so the actuator gets pulled forward as the truck moves. Kind of like pulling something with a chain. If you creep forward just a bit after you stop, it may help make it less violent.

My trailer, which is a Ranger Trail has no movement at all as to what you guys are saying. Mine is an '05 tandem which must have been blessed by the Pope, lol.

Also, make sure the Master Cylinder is full and brakes have been bled. It can also be a weak shock in the Surge brake connector.

I'd say it's the Hitch and Receiver. Shake the hitch and see if there is a lot of movement. A little is normal. There are Hitch stabilizers and tighteners that can help.

I put one of those on and they work great

Sounds like your shock absorber in the actuator is shot
