Great points folks! First of all we did have a TPMS which was set to the recommended specifications and it did alert us, but the damage was done. Next time I will lower the TPMS thresholds for the Toad for quicker response time.
I think Dale nailed it. I think they kinked the conduit and forced a doubt that eventually failed. Don't think I can prove it, and it would take considerable time and effort to prove and I've not got that time.
Next step is to find someone who can tie to the LED on my dash that came with the Ready Brake to my brake light activator so I will know if my brakes stick regardless of the device I am using.
