Don't use your brake. Approach the area you want to stop very slowly, first using your brake to slow down, then when practically stopped release it and coast very slowly forward, you want to find a slight incline that starts pushing you backwards, when you feel it, push forward a little bit, then let it push you backwards. But also try not to think of rolling forwards/backwards but think of applying force forwards/backwards.
