I HATE to throw in the towel on major parts replacement but, I think its time to replace the EBTCM.
The EBTCM has an internal microprocessor that examines ALL of its inputs and makes braking adjustments/decessions.
IF,,,,,,,,,,,,,,, All the sensors are working properly and you are having these issues, the Microprocessor is making irrational computations.
My 02 ZO6 (less than one month out of warranty
) had the a simular isssue. At exactly 42 mph, the EBTCM would spaz out and throw a DTC. It went into its fail safe mode.
I brow beat GM and they gave me $1500 towards a new car purchase. Lucky for me, I was in the market for a 2006 C6. Got a good deal on the C6 and then I layed the $1500 certificate on them.
I had to have the EBTCM replaced because the microprocessor was defective. I think you are in the same boat.
