A pressure bleeder kit from m source is like 40 bucks or something. Well worth it.

x2, I have a Motive pressure bleeder, ~40 bucks, makes this a quick and easy one-man job.

I have been using a gatorade bottle and clear tubing, never had any issue. even with freshly rebuilt brakes involving, hard lines, soft lines, calipers and master cylinder (redoing it with new seals).

hook it up to the slave bleeder, keep bottle above hub but below master cylinder, fill master cylinder container, little gentle bumps on the pedal to prime the system and then slow half strokes to push liquid through.

I tried the gravity method with 4 setups. it was slower than mud.
