Brakes grabbing

BogieMeister

During recent outings i find that after a couple of hours on the road the right tire skids when the brakes are applied. Ive tried adjusting the controller but whenever i set the level high enough to have ant effect the right brake grabs. My unit is still under warranty but i wonder if it is a simple fix i could take care if myself. 

It is more than a little embarassing in city traffic. But it does draw a lot of attention.

That sounds like brake adjustment rather than a controller issue.

There are some other threads about things like this, they might help.

@BogieMeister I had the same problem. The brakes on our new 400 were grabbing on our second trip out (about 1000 miles). Adjusting the brake controller made little difference. Then I remembered that I had read that they are manually adjusted and needed to be adjusted after the first 200 miles. Since I was traveling away from home, I took it to a nearby auto repair shop that did the adjustment and the problem went away. I have since learned that the manual adjustment should be a regular, periodic maintenance item since they aren't self adjusting!

I wrangled with this my first couple seasons. After adjusting the brakes, fiddling with the controller, and maybe just plain old "breaking in" the problem finally went  away.

I do keep my brakes dialed back pretty far as I have a reasonably substantive tow vehicle. However, they do appear to engage when most needed such as during quick stops or stops on steeper downhills.

Another thing I found is if for any reason your TV battery has been disconnected (like replacing your TV"s battery), the brakes will pulse and grab till you go back threw the original set up again. Art
