See the link above from ORbiker
I just had disc brakes installed at the shop which is detailed in that link, cost $2600 for all parts and labor. I have too little experience and too many years of life to do the installation myself. I made the decision to have the work done there on the basis of this web article to which the link leads.
We have just one problem. This fine system is not compatible with the GM Integrated Trailer Brake Controller in my 2008 Duramax/Allison Chevrolet, even though I was assured that it would. I have three options (that I am aware of) to solve this problem:
1> Install an after-market controller such as the Tekonsha P2 or P3
2> Install an adapter, HBA-CAM which is available for about $85
3> Wire magnets inline to "fool" the ITBC
Here is my urgent request: Is there anyone who has actually used the HBA-CAM adapter in a GM truck? That would be my choice if I knew that it would work as advertised.
As information to any who are considering a upgrade to disc brakes with a GM truck, here is what I have learned:
GM official position is that their ITBC is designed for electric brakes and not for electric over hydraulic systems.
There are work-arounds. I will report back on the solution I have found--I am still working on it and will appreciate any feedback on this forum. Please help!
