A brake torque control system of a host vehicle includes a memory and a brake torque control module. The memory stores, for a braking event, multiple values indicative of whether an object has been detected forward of the host vehicle, a speed of the host vehicle, and an expected stopping distance or an expected stopping location of the host vehicle. The brake control module, based on the values, operates in an anti-pitch mode and reduces at least one of an amount of brake torque requested and a brake pressure applied for a last remaining portion of the braking event to reduce pitch of the host vehicle prior to coming to a complete stop and to not reduce the at least one of the amount of brake torque requested and the brake pressure applied for a portion of the braking event prior to the last remaining portion of the braking event.
