Hi SFG,
I can't help, I only know the brake cut off the fuel because I dry the brakes off after washing the car, I drive gently with the brake lightly on while on a light throttle just to warm the discs and pads so the water evaporates and doesn't mark the discs or pads whilst in the garage,
Hope you sort it soon
