Stop in for a cup of coffee

Got my brakes back together with new wheel cylinders. Everything else looked good. Only thing when all done, not holding as tight as I think they should. Had wife press the pedal and I could still turn the tire. Not easily, but usually if I check this way it's a lot more grab. I test drove it and it stops good and straight. And I know fronts do most of the stopping. Just think it should grab better...
