Re: GMC integrated brake controller and hydraulic trailer brakes
markm wrote: Hi all: considering a GMC 3500 HD DRW. My current 5er has the Titan hydraulic disc brake system, which requires my Prodigy P3 brake controller to be set in the hydraulic over electric mode. My question has to do with the integrated brake controller on the GM HD trucks. Will the integrated brake controller work with hydraulic disc trailer brakes? 2015 and newer HD trucks have hydraulic over electric support from the factory. If yours is 2014 or prior, the problem is the integrated controller doesn't sense the electric over hydraulic actuator and so it never senses a trailer is connected and thus never activates the trailer brakes. You can get it working by wiring a regular electric brake magnet in parallel with the actuator -- this will fool the truck's integrated brake controller into operating as if there was an electric system on there. See here for an example solution..972Views0likes0CommentsRe: Check your leaf spring shackles!

The only repair shop up here in a hundred miles charged $125 CAD for the repair... for two shackles (that aren't even the same length as the original) and a bolt! I just ordered the EZ-Flex for $300 shipped to Fairbanks and will probably get a new set of springs as well. An ounce of prevention is worth a pound of cure.970Views0likes0CommentsRe: Check your leaf spring shackles!

Climbing around Fancy Gap on I-77 and with no warning truck says "power Reduced". Dropped to 15 mph towing the below 5vr up the rest of the hill. Gauges all good, DEF good, fuel filter good. Nothing giving me any warning or explaining the power reduction. Could it be that the heat and climbing just put the system in to reduction to protect it? I shut of the engine later at the nearest exit/gas station and it reset and pulled fine the rest of the 30 miles to Wytheville KOA where we are overnight tonight. Any ideas? I had the same thing on my 2015 duramax as well. Only happened when pulling long grades at WOT. In my case, it illuminated the CEL and stored codes P0234, P2263, and P2599 which have to do with turbo overboost condition. In my case it was caused by a loose intercooler pipe clamp. In your case I would read the codes and do a boost leak test. Couldn't hurt. The air flow and pressure sensors in the trucks are incredibly fussy and expect values within a narrow range. See here for more if you have the above codes: http://www.duramaxforum.com/forum/11-16-lml-duramax-powertrain/909297-p2599-p0234-p2263-codes.html#/topics/909297304Views0likes0CommentsCheck your leaf spring shackles!
Just went through a pretty rough stretch of the Alaska highway northbound between Destruction Bay and Beaver Creek, YT. Stopped for fuel, and found this: I'm lucky the axle didn't rip off! Apparently it's a common problem up here. I suggest to anyone with a decently heavy trailer with OEM suspension -- upgrade your spring shackles! Or for that matter, upgrade your suspension in general! All it takes is one pot hole to break something and potentially cause a fatal accident. Trailer specs: Total weight: 13,000 lbs Weight on axles: 11,500 lbs Axles: Tandem Dexter 7,000 lb Miles on trailer: ~ 20k Larger picture of the trailer (yes, it's a "tiny house"): Currently getting a new set of shackles installed in Beaver Creek, YT and have a Dexter EZ-Flex kit on order. Anyone have recommendations for a suspension shop in Fairbanks?6.4KViews0likes19Comments
