has anybody tried this technique before... how well does it work? does this help you avoid lifting the car & removing the wheels? is it more difficult to do than lifting the car?
also how bad is it if you do not cross bleed your brakes. (ie. do the fronts first then the rear?)
also it was always my idea that you pumped the brakes several times... til the brake pedal felt stiff(er)... hold the pedal down and open the purge/bleeding valve until the brake fluid came out.. then close the valve before releasing the pedal... and repeat until you get a nice stream of brake fluid coming from the valve.... is this incorrect?

Ok I have a trick for you that everyone should note in their long term memory...
It's an easy way to get all of the air out of your lines and master cylinder. First you will need someone else to help you and a brake line wrench if you don't already have one for your brake lines.
Alright your going to bleeding your brakes at your master cylinder. Have your friend very slowly press on the brake pedal and then when he's doing it crack open one of the brake lines coming off of the master cylinder and then close it before he reaches the floor with the pedal. Do that with all of the brake lines a couple of times or as much as you wish. Brake fluid shouldn't come out of the lines that you crack open only air. It works awesome and I thought I would share it with you guys. Also for anyone that pumps the brake pedal several times before cracking the bleeder that's a big no no I've learned. In the ASE Newsletter we get at school they said that pumping the brake pedal between bleeding sequences. They said it can damage seals and other stuff.
And if you think you have a leak in your brake booster then I want you to do these two things for me.
Get in the car close the windows turn the radio off and start the car and turn it off and then slowly push down on the brake pedal and it should make a whooosshhh sound. The sound should start slowly as you start pressing on the pedal and when you press more and more the whoosssh intensity should increase.
If it just goes WHOOOSSSSHHH and stays the same and doesn't do like I said before then you have a problem with the air control valve in the booster.
Then I want you to start the car again and turn it off and then pop your hood and then take the check valve off of the brake booster and if the valve is good then the sound should make a pssssss sound. If it doesn't make any sound then your check valve is bad.
