Trailer brakes

So just bought a new to me sled trailer. Brakes on all 4 wheels. Installed a new protigy2 controller in the tundra. The brakes are working (buzzing noise) when applied but they are not slowing the wheels down much at all. We jacked up the trailer one side and spun the wheels, when brake applied I can feel more resistance, but they still spin by hand. I adjusted them tighter, no luck. Gonna tear into it this weekend.... but I doubt it's wiring related. I hear buzzing... am I on the right track?

I'm wondering if the magnets are worn or weak and they can't slow the wheels any more....

Any help or insight is appreciated

 

I thought the Prodigy controllers gave their
output based on forces "felt" in the controller. So essentially it would only work when you are actually driving and braking?

I did a quick search, maybe this will help..

I guess I was assuming you weren't using the "manual" lever.. Here is another article that may help...

Yeah I read a lot on that website last night. I set up the controller correctly. The trailer is not slowing at all. I hear the buzzing I can feel very slight resistance when spinning them by hand... that's it tho

 

Gotcha. Sorry I can't help any further.

 

Just curious how you made out with this?

 

So far they are working. Each time out they work better and better. Smoked the front axle wheel bearings for some reason? Replaced those with new races and we're back in business. Pita tho... with new brakes it always needs adjusting. Then I can mess with the controller too to fine tune it

 

Interesting. Glad they are at least working for ya

 

Yeah me too... I towed the other day with just 2 sleds on it. HD to turn the controller way down... was locking up tires at stop lights.
