Brake Actuator Groan (Noise)
 

So my trailer for my V220 Supreme has been making some pretty nasty noises when coming to a stop. The moment I begin to decelerate a groaning noise comes from what sounds like the actuator on the trailer tongue. Once I begin to pull away from a stop it goes away. Any ideas? Could it just need to be lubricated or something?

That's the brakes

Check your fluid for water

I've already got new brake drums on order with a plan to totally flush the lines. When I was hauling the boat yesterday it just really sounded like it was coming from the actuator not the actual brakes.

I had the same problem, I sprayed wd-40 all up in the tongue and it went away. I have an extreme trailer and they have a plastic cap that covers the cap for the brake fluid. Under the plastic cap is where I sprayed to the WD to fix the problem. I would just go to town on the tongue with wd-40. Spray everything that looks like moves.

So I've got it fixed, here is what I did:

Sprayed everything that moves down with WD-40.
Replaced the brake drums.
Flushed the old fluid out (I Really think this was the problem, because after I got all the air and old fluid out, the actuator felt much firmer than when I started).

Everything is good to go now!
