Van Brakes

1998 Ram Van 1500 V6/Auto 2w ABS? Have what I consider excessive peddle travel. Brakes work good but do not inspire confidence. Does not pump up. Pulled rear wheel adjustment Ok. Give a click or two on emergence brake to take up any slack No difference. My 92 Van had much better feel & less peddle travel. I'm wondering if the rear brakes are even working properly Any easy checks ??? Thanks Lynn
