Not exactly sure what you refer to.. Bleeding the wheel (caliper's) after changing pads, replacing (flush and refill fluid) or just insuring there is no air in the system?
I use either a Mityvac vacuum pump with a catch bottle and / or allow gravity to fill the wheel cylinders and do the final pull with the Mityvac.
As a rule, your master cylinder will always be higher than your wheels and brake fluid is pretty viscous so it flows readily and fluid always flows downhill.
I do a brake fluid flush and refill every few years. Fluid is cheap, even DOT 5.
