I've been using this method for years and it's great for two reasons.....takes one person and it also flushes out the brake system. It's called a gravity bleed. Open all the bleeders, remove the master cylinder cover and just keep pouring fluid into the master cylinder until you have poured about 1 quart of fluid thru the system. Close all the bleeders, refill the master cyl. and that's it. This works 99% of the time. The other 1% of the time you'll need to have the system pressure bled due to a variety of causes. Try it, it's easy.....and good for your brake system!
