Sound like you need to adjust the shoes out! If they are to far away from the drum there isn't enough fluid in ONE pump to engage them, but by pumping fast you over come the fluid shortage. Jack the wheels off the ground and adjust until the shoe drag the drum.

Let us know if this fixes your problem!
