Gravity. It's slow, but you can just do other chores while keeping an eye on the MC.

If the fluid won't drip out by gravity, I just pump the pedal a few times to wash out the scum that's holding things up.

When bleeding I always replace all the old brown fluid with new, clear fluid. New fluid consumed is always about 2-3 cups, no matter which car. It takes a glass jar to be able to see the color difference, and you must empty it often be sure only clean fluid is arriving.

I've witnessed mechanics do gravity bleeding with no hose. But I prefer using a clear hose and a glass jar with the hose submerged. I have a box with all the brake tools and supplies needed just for this. Actually I use 2 glass jars. The 2nd one is just to show the color of new fluid because many times it's hard to discern the color inside a garage unless you have something to compare it to.

Never had any luck with suction, as it would always pull in air bubbles by way of the threads on the bleeder valve.
