So I took my Truck in today to have it looked at. Pretty much what we've all come to expect, cant find anything wrong, no surprise there. Anyway they gave me this document with a lot of information in it you guys may find helpful. There's a dedicated section about Electro/Hydraulic brakes. Before I get into that, I want to tell GM that there doc filled with why it maybe the trailer is offensive at best. We all have new trucks here. You know what that means GM, we had a truck that we traded in on your 6 figure trucks that are having brake problems that didn't exist on our previous trucks. You know what that means. ITS YOUR TRUCK, YOUR LACK OF PROPER TESTING, AND YOU PUTTING LIVES AT RISK !!!!!
Some 22k pound missile with no brakes is going to kill someone, and then you're going to be on the hook for millions, because of a $100 part. My Ram - go in select Hydraulic over Electric, 5 years no problems, hmmmm. Apparently it doesn't require an adapter, or Plug, and its not my trailer. We buy these trucks for pulling things, you know like in all of your commercials, and you cant even mange to get that right, but my seat will give me a back rub. You need to adjust your priorities.
Moving on. The doc states that applying the brake to lightly, or the Gain not set correctly can cause the pump to not reach the 20-30% to activate the pump. "This is normal"... "Pressing the brake pedal harder will help alleviate the concern"
So don't slow down like a normal person, slam on the brakes, then they'll work correctly, seriously !!
So I'll be hooking my 5th wheel back up, and testing to see if I'm experiencing these issues. This first time GM customer maybe their last GM purchase ever, and traded before the first payment is even due.
