#285 of 303 Horse Trailering and a Silverado 3500 Dually by doonster

Here's my issue - I trailer 3 horses with my 2008 Silverado 3500 dually - 6.6L Turbo diesel - I have a fully aluminum Hart LQ gooseneck trailer. Here's the 'problem' - when braking (typically coming to a stop sign or light) I often experience a back and forth lurching of the vehicle and trailer. It is not a brake pedal pulsation - I feel if more through the entire vehicle. If I depress the brake pedal really hard it will typically moderate, or go away entirely. If I'm in the 'Tow-Haul' mode it is usually felt less than when I do not have this engaged.
      Is this an issue of the amount of weight I am towing? A brake issue? Is this all normal when towing a rig like this?

does your brake controller have diferent settings that allow gradual braking? I would start with that. could the brake drums on the trailer be warped?

Barrail - Thanks for the reply - the brake controller is a built-in system by Chevy - it allows for adjustments in half increments - 1.0, 1.5, 2.0, and so on. Unlike the Prodigy unit on my former truck, this system doesn't have a 'boost' option. As far as the drums/rotors are concerned, that had crossed my mind, but I haven't checked these yet. Would this be the kind of thing that wouldn't be noticed unless I was trailering a heavy load?

Hi Doonster i assume you are talking about when attatched with your air.? I just purchased a brand new 2011 dually have two compressors feeding one tank and when tapping the brake pedal can dump two thirds of my air. it just caused me a major incident that shunted my 43 ft trailer and locked it up coz of insufficient air. They first thought the bleeder valve got it home without towing and has not fixed the problem. Have you found a solution ?

Hello doonster,
 
I can ask our technical assistance center this information if you like. On my end, I need to provide the last 8 digits of a vehicle's VIN when I do this. If you're willing to provide that information, please email it to me at the address listed in my profile.
 
Best,
Sarah

Problem fixed. With two compressors supplying
air to tank u need a priority valve otherwise
the float lever will flick from one valve to other
and dump air I used a protek valve. As well the air hose
must be atleast 2 metres curled up between them.
Works like a charm .

my problem was no trailer brake lights,and maybe a turn signal was out. After exhausting my limited abilitys, I took it to my local mechanic and his son dropped what he was doing to look up the wiring schematics on some web site he subscribed to. the fuses were all good, and everything on the truck worked. the problem was only on the trailer harness. sorry for the long explaination, but the resolve was an faulty relay on the back of the fuse box under the dash, easily accessable by pulling of the dash board. hope this helps.
