Should I bleed the lines with the car running or not in a Power brake system..

 

i always do it with the car off, no reason to waste fuel

 

Also makes it easier to get 'real' pedal feel, that way you can tell the difference between spongy and firm, whereas the power booster would make that rather difficult.

 

I've never bled it with the engine running and I've never had a problem.

 

no question about that. engine off.
The booster is only there to make it a bit easier on your foot.
makes no difference in the bleeding process (how much air is going out at what rate).
And as Tad says with powerbrakes you never know if the thing is properly bled.

So aye .. leave engine off

 

Thanks guys.. I bleed the lines tonight.

 

when you don't have any speed-bleeders or bleeding container, then you'll need someone else to help you.
Do you know exactly how the bleeding process works (just to make sure)

Yea, Ive done it a couple of times, I just didnt know if I should run the car or not. I figured not.. but had to be sure.

The wife is going to be my pedal pusher..

 

don't forget to ask her if "it's hard yet"[sm=roll.gif]

 

LOL

Don't be short with her if she screws up somehow, if you do it won't matter how hard "it" is, you'll be on your own.
