Disc brakes NOT working with GM integrated control
This applies to my 2008 Silverado Duramax/Allison 2500.
We had brakes upgraded to disc brakes which are EOH (Electric Over Hydraulic). The GM (General Moters) ITBC (Integrated Trailer Brake Controller) is NOT designed to work with EOC systems and ours DID NOT.
With help from members of this forum and from the NuWa Forum I found three possible solutions:
1> Bypass the ITBC with an after market controller such as the Tekonsha P2 or P3. I really did not like this idea, but knew it would work if I couldn't do anything else.
2> There is an adapter, the HBA-CAM (Hydraulic Brake Actuator-Control Adapter Module), which is designed to work with my HydraStar actuator. This costs about $85. I was certainly prepared to try this before the after market controller
3> Some very good friends on this forum and the NuWa forum suggested that I try electric brake magnets wired in ahead of the actuator which would "fool" the ITBC into sending the current that would engage the actuator. They were confident this would work for me because it was working for them.
Today, I happened upon a tire/trailer shop where the owner had just replaced brakes for a friend. We made a deal for two brake magnets for $ 5.00. I came home for lunch, wired in the magnets and my brakes and ITBC are working normally. I have just returned from a test drive with delight.
I am hoping my experience may help someone else. BTW, I understand that the more recent GM models (last few years) are now compatible with EOC systems. That would be great.
