Its actually the reverse, if its sticking it will be sticking on and therefore creating friction slowing the car when it shouldnt. If it was sticking when the brakes were being applied it would be sticking very hard as the hydraulic pressure on the brake caliper is significant. Where as the return pressure on a caliper is very light
The ECU was most likely getting confused in that the speed sensor said a speed and the car would expect an amount a fuel to be needed for tick over however the extra drag was casuing it to over copensate. Once the drag inerti was overcome the car would have the effect of over reving or surging.
