Towing Brake Problem

Hello, I am looking for some help with trailer brakes. I have a 2001 Mountain Aire, when I plug in my trailer with electric brakes and am rolling down the road as soon as I touch my brake pedal the wheels on the trailer lock up. I have no brake controller on my rig and don’t understand where the electric trailer brakes are getting the signal to brake the wheels. I cut the blue brake wire in the trailer wiring box to stop this from happening. Is the only way to resolve this problem and have trailer brakes to install a brake controller ?

From your description, it sounds like you're applying a "non-proportional" brake signal to your electric brakes hence they are being "fully" applied! Brake controllers apply "a proportional" signal when braking...

Sounds like a previous owner , hooked the blue wire up to something other than a brake controller.
Have you tried to find the under dash end of the wiring?

You describe brakes that are being applied by the power from the brake lights. Check wiring from trailer connection to brake magnets. I believe you see the need to add a brake controller with electric brakes. If you suspect a previous owner monkeyed with the wire harness for trailer brakes, the simplest and fastest would be to install a brake controller and new controller wire to trailer plug.

You need a brake controller.

If you drive without brakes on the trailer what will happen is that the trailer will wrap around the side of your coach in a panic stop situation.

It's so weird being the same age as old people.

I can't imagine pulling a 40' trailer without brakes! You need a brake controller...without brakes that trailer will push you into the ditch (or worse) when in a panic situation...or, as mentioned above, wrap itself around the tow vehicle, not to mention the rapid wearing of the brakes on the tow vehicle.

You sure we're not being trolled? Seems over the top to me.

Where did the fact "pulling a 40' trailer without brakes" enter into the thread? The OP has a 2001 Mountain Aire that's 40' long, not his trailer.

Sounds to me like the brakes were attached to the brake light circuit direct instead of via a controller.. OR. there is a controller with the gain set wide open that you do not recoginize as such.

My recommendation, assuming this is a trailer, with electro-magnatic brakes, is a Tekonsha Prodicy P-3 or better.. but then.. I'm from Tekonsha. (The Township, not the company).
