Heya, i replaced my trailers brake plates, electric, and now they show as working on the display in the 2016 2500, but the brakes won't lock up even at 10 setting, which they used to. Jacking the sides of the trailer, the brakes will work when pinching the brake controller but not when hitting the pedal brake. Changed the 30 amp fuse, no difference. Could it be the module where the spare is ? Thanks for any help. M

Are you getting any "service trailer brake" message on the dash?

No codes on dash , no. Shows the brake level of output to trailer on the dash, like a percentage of gain. I used to be able to lockem up when I had it turned up, single axle 1960 airstream so shes lite.

So sounds like the Integrated Trailer Brake system is working on the truck side correctly.  

 

I'd look at the trailer side, make sure everything is hooked up.  

 

Do you have another trailer you can hook and test the brakes with?

No, unfortunately.  When I hooked up the new brakes I left a bit of the old brake wire to hook up the new brakes to give me a little more wire, maybe too many connections? I also hooked up a cap to the brake lights last year, maybe ? Thanks for this

I don't think the cap would cause it, unless it was tied into the brake lamp circuit for the 7 way?  But even then, not sure it would cause.

Only would be problem if it was tied to the trailer brake output in the harness - I doubt it.

 

I adjust the brake shoes on my trailers to a moderate drag. (Light drag being turns with no or little restriction and hearing a slight noise when spinning, heavy being hard to spin by hand. Moderate can be spun but definite contact and noise. I like it this way to make sure my shoes get a good bedding to the drum and strong sense of engagement when in use.) As long as you aren't getting any errors, I'd start with adjusting the shoes.

Thanks, I like that suggestion, once i get the electrical thing figured, I will do. BTW they are self adjusting, but the threaded bolt on the bottom is how we adjust them right ?

      Mangoal or FitcamX OEM Dashcam?

      By MANGOAL · Posted

      Late reply, but yes—it works on the SLT trim. Compatibility comes down to the plastic shroud shape behind your mirror, not the trim badge itself. On the SLT with auto-dimming, it uses a plug-and-play Y-harness off the mirror/rain sensor power, so no need to run wires down to the OBD port. If anyone's ever unsure about fitment, just drop a photo of your mirror housing and we can double-check it.   Appreciate the detailed feedback on the install! On the windshield glare—we actually took feedback like yours and developed a dedicated CPL (polarizer) filter to cut down dash reflections on sunny days. If you're still running the cam, shoot me a DM. I'd be happy to send a CPL filter over for you to test out—no charge.

      Yes, every time the developer updates his code, you must recompile. I will private message you with the latest because it changes pretty much with every version.

      Transmission Temperature Hitting 220s

      By Grumpy Bear · Posted

      After I wrote that reply I went for a ride. 85 F out. So trans started at 85 F and it shifted the same as it did an hour latter at 168 F. I've never actually recorded the to cold to shift point but it is under 32 F before they start hanging on to a lower gear or leaving the converter unlocked. Both intended to heat fluid.    Yes, brake or bake. Absolutely.      Your welcome. True research ended decades ago. Field trials are still in play.    There is a thing called oxidation onset temperature. This is the heat related oxidation not the O2 exposure kind. For mineral oil that starts at 140 F. So what happens after 140 F? Each 20 F cuts fluid life in half! Does using a Full Synthetic improve that? Yes! By how much? Depends on the base oil type and a few other factors. But enough to notice. Some esters are even higher. There are even synergies between types the will raise it higher than any one component is alone.    Then there is "Hindered" oils. Antioxidant additives. Hindered Polyol Esters can sit at 500 F for years in a turbine.   When a blender brags his oil will 'take 500 F" in service he doesn't specify for how long. Water will dance on a 500 F hot plate for several seconds. @newdude put up a chart showing the relationship between fluid temperature and it's life in an automatic transmission. Here's a version of that chart for Group III based oils. These temperatures are those in the pan as observed as 'normal'. that is you drive as you do for as long as you do under what load you ask of it and whatever that temperature is this graph applies to. Flash temperatures of a few minutes isn't what his means.    Note that fluids held at a constant 240 F have a service life of only 20K miles. 220 F explains the factory exchange limit, eh? My equipment I keep under 180 F and I'm good if the cooler will hold it as low as 140 F. But that's me.
