My brakes suck

On an extended road trip in the western states. Never had much of a concern with my brakes back home in eastern Canada. But in the serious downhill grades of the rockies and other assorted ranges I find that I'm relying far too much the TV brakes.

I adjusted the shoes but still not much of an improvement. Measured the voltage and current. All looks good.

I'm using the integrated brake controller in my 2012 F150. With the brake controller set to 8, the measured current is 10A.

Thinking there might be something wrong with the brake mechanism I overnighted new self adjusting units from Inland RV. (Thanks Andy) and installed at our campground at Mammoth Lakes, CA.

While better I'm still running with the brake controller on max gain. (10).

I'm at a loss as what to do next. The only thing left left to change are the hubs.

Thoughts ?

I'm not sure what TV you have, but have you tried using the transmission to help? Maybe take it out of overdrive or use a lower gear? Just a thought.

The gear you climbed the hill in is the gear you go down the hill in.

If you are descending a hill in D you may loose the the brakes altogether due to over heating.

Self adjusters will not correct the problem. If your TV does not have a Tow Haul Mode gearing down or an exhaust brake are the first 2 choices.

If you have Tow Haul tap the brakes just as you start down and the trans will come down one gear. If you start to gain speed in that gear hit and hold the brakes to cause slow down and the trans will comes down another gear. When using Tow Haul watch the engine RPMs and don't let it over rev. The Tow Haul will only do so much and brakes are required after that. If you have to use the brakes because of over rev stop all together and start off again in a lower gear that will hold your speed below the point of increasing speed.

Well can you get the trailer brakes to lock? If not then I would say you have trailer brake problems. You need to check voltages at the brakes themselves to make sure you are getting enough current. Conventional brake controllers are on/off and are not proportional. I don't know how your F150 controller works but you might want to read up on that. Drum brakes will overheat pretty quick and if you have your foot on the brake they are full on the whole time unless your controller is proportional. I have never been impressed with drum type trailer brakes.

The retrofit of disk brakes for your Airstream at the factory will likely melt the AmEx card. There are few dealers that have even a smidgen of knowledge on how to work on the trailer version of Disk Brakes.

As mentioned above, go downhill in Tow/Haul mode - it will help.

I was towing today in rather hilly Vermont, and was amazed at how the engine braking will keep the whole rig at 50 mph down some rather steep grades.

Are all the brales working on your trailer?

A brake controler like the Prodigy has several settings for trailer size and anticipitation. I think a new controler is in order.

You can not rely on trailer brakes on long down hills....

You have got to slow down and use the transmission along with occasional use of the trailer brakes to keep your speed under control.

I'd suspect you've fried your brake shoes and possibly scorched your brake drums.

LFC is absolutely right. Relying only on trailer and TV brakes in the mountains in a recipe for damage, possibly disaster. Slow way down before heading downhill, and keep it that way with your transmission; use your brakes only occasionally.

Agree with Eubank, LFC and others.


Before I would take another trip, you might consider servicing the brakes on your AS.

We don't know mileage on your AS or previous use. If you don't know how, take to RV dealer. Brakes are standard enough a reputable dealer can service.

Let us know..

It's all been good advice so far. I'd like to add slow down. Don't do the posted speed limit on the down hill side. It's figured out for a car in good weather conditions, not for larger vehicles that may be towing. Crest the larger hills going 5-10 mph slower & try to maintain the slower speed all the way down.

I recently upgraded from a 2008 F-350 to a 2011 F-350 and a newer to me airstream with hydraulic disc brakes. My first trip the brakes didn't work well or smoothly and I had the gain set for 10. I figured out that I could select electric or electric over hydraulic and as soon as I changed it to electric over hydraulic it worked great. Maybe your computer is set for electric over hydraulic and you need to change it. I can access the settings under truck applications.


Regards,

Reganzo

Braking Controller

Just a thought...

I tow and brake without a problem. I use a Tekonsha Prodigy® P2 Electronic Brake Controller. it controls the Panamerica's stopping without fault. It was installed by CanAm RV in London, Ontario. Andy's knowledge and people are great on any towing issue. Give him a call.
