kuhar69 Posted February 13, 2013 Share Posted February 13, 2013 (edited) I have a 2003 RB688S Tri axle dump truck I need to tow a Cam superline trailer which is a 14,000 GVWR 12,000 lbs carrying capacity.The trailer has electric brakes on both axles.I have a RV plug on my pintel plate. I have been told to install an air actuated electric brake controller??? I never heard of one is this good advise????

Dougsr Posted February 13, 2013 Share Posted February 13, 2013 Most of your electric brake controlers don't conect to your brack system They have a pendulm in them. You set the level then set the gain like you want it. You still have the option to manually use the trailer brake.Doug Quote Link to comment Share on other sites More sharing options...
kuhar69 Posted February 13, 2013 Author Share Posted February 13, 2013 I just spoke to a gee from Hayes controllers they say the best option with that heavy of a load is the air actuated model it works off the trucks air brakes somehow??

thomastractorsvc Posted February 13, 2013 Share Posted February 13, 2013 I would say it is plumbed in to the air brake line, probably at the brake switch area, I have seen regular controllers on air brake systems with the electric that ties into the brake light switch that signals the box to activate and they seemed to work fine, like Doug said most now work of a pendulaum set up, just make sure that it is a quality controller most will be around $120 Quote Robert"I reject your reality and substitute my own."

farmer52 Posted February 13, 2013 Share Posted February 13, 2013 Hayes makes a controller for air brake vehicles.http://www.hayesbc.com/?page_id=1065 Quote Ken PRR Country and Charter member of the "Mack Pack" Link to comment Share on other sites More sharing options...
2stacksuperdog Posted February 13, 2013 Share Posted February 13, 2013 We had one in one of our old R-models it worked off the brakes and had a little button on for just braking trailer Quote Matt Link to comment Share on other sites More sharing options...
kuhar69 Posted February 14, 2013 Author Share Posted February 14, 2013 I'm gonna go with the Hayes air actuated electric controller. Quote Link to comment Share on other sites More sharing options...
Freightrain Posted February 14, 2013 Share Posted February 14, 2013 I have a Warner. White box, red knob on the front for manual activation. Hooked it into the treadle valve and works great.I tried a "car" type pendulum, but with a very bumpy road it was BAD. The newer electronic versions are just as bad. They just ramp up to full power no matter what you want. That sucks too especially going down a long hill. Keep having to get on/off the brakes as the trailer kept dragging hard after a few seconds.http://www.etrailer.com/Brake-Controller/Warner/1300-80.html?feed=npn&gclid=CJPFwfiytrUCFYxDMgod-g0A6g Quote Larry 1959 B61 Liv'n Large......................

kuhar69 Posted February 14, 2013 Author Share Posted February 14, 2013 I see the Warner's sell for $475 the Hayes is $225. Both of these work on the same principle correct?? Quote Link to comment Share on other sites More sharing options...
Freightrain Posted February 14, 2013 Share Posted February 14, 2013 I would guess. It takes air input and moves a rheostat to apply electric brakes. I've had my Warner for 10+ yrs without issue.
