who's boat ??? BTW found this !!
Final chapter in the saga of the brake delay. I finally bit the bullet and relocated the ground wire on the pump. It is now in an isolated circuit directly back to the truck battery (it had been grounded to a common ground in the trailer). Delay time now is 1/2 second or less on manual override and not noticeable with using the brake pedal. The system now works as advertised and the secret is that the ground path MUST be directly back to the truck battery

When you pull the "rip cord" on the breakaway brake cable, does the brake pump start pumping instantly?
I usually test my brakes before each pull by having the ignition ON on the truck, but w/o the engine running. I don't know if your factory system will work like that. I test it both ways by pressing on the brake pedal, and listening for the the brake pump to engage; as well as using the manual actuator switch and listening for the brake pump to engage accordingly.
What I'm getting at...
Is your brake pump delaying in starting to pump pressure to the brakes, OR is the delay you describe a delay BEFORE you feel braking power; after the pump starts pumping.

Alright, well that does narrow it down a bit. Either that pump is not pumping effectively; or something between the pump and the calipers is jacked up. It might even be a kinked line.
My EoH pump on the trailer supplies enough pressure to immediately throw brake fluid 30 feet when there is an open in the system. I found that out on the trip up there to Boyne when I broke a brake line on the trailer outside of Cleveland. I'd look to see how effective the pump is operating and pushing fluid down the line by opening the furthest brake bleeder and checking things out moving forward.
