Lots of threads and opinions on it. Personally, I prefer the push-bleed using the big syringe.

I use regulated air into a tube and the other end in a hole in a cap from a brake fluid bottle, it screws right on to our MC Resevior. i only used about 15 psi, make sure you have enough fluid and go to town!

Either buy one of these:

Or "Reverse" bleed using a steel oil can and some tubing to push the fluid "up" the line. Use a bulb(baster) to suck as much fluid out of the MC as possible, then simply crack the bleeder and push fresh fluid through. A little awkward at first, but you'll find you're own rhythm.

Either way...no "helper" required. I personally used both methods. Reverse bled initially then used the vacuum bleeder to ensure no air entered. Ditch the reservoir and simply fill the MC when needed. A great tool to replace all your old brake fluid as well. I've used it on several vehicles. Especially nice on larger trucks with long lines!

73 MGB. Tires: Round, black, hold air. Oil: Sometimes old, sometimes new...always slippery. Oil filter: Yellow, usually full of oil. Carbs: 2 SU HIF. Distributor: Yes. Headlights: Not that bright but bright enough. A bunch of other stuff most cars have but not really important enough to itemize. Oh, wait...it has a cool sounding exhaust with stickers on the chrome tips. Really slays the ladies...

Use an aquarium one-way air hose check valve (used to keep water from back-flowing if air pump quits)
found at any Pets Mart, etc. It's cheap and works really well as a one-man brake bleeding system.

(I learned that here on this site.)
