The ABS controller should not affect the "feel" of the brakes unless during slippery conditions or panic stop where the wheels will "lock" up due to the non functioning ABS feature. Otherwise the pedal should feel the same and braking function should be the same up to the point of "locking" the wheels up into a skid.

In fact, my controller just started malfunctioning a couple of weeks ago but normal braking is unaffected in feel and function.
