Bleeding brakes with engine on or off

[franco802]

Are you guys bleeding the brakes with your engine on or off. On vehicles with power brakes I have always bled them with engine on.

I've always bled them with the engine off becaue thats how I was taught I guess.

I wonder if it really does make a diffrence.

HMMM........

I dont think it matters but i've always done it with the engine off.

 

[muddybuddy]

i always do it off

I always do it with the engine off. takes too much to feed the motor just to bleed the brakes, unless it is better to do it with the engine on. safety first but Ive never heard that the engine needs to be on to do it properly.

I do it with the engine running. Which part of Ar are you in Big Dan?

Engine off when using brake peddle. I made a brake pressure bleeder and no problems since...Pressure Bleeder Click Here

AZ can you repost the pictures of your pressure bleeder? The link on here doesn't work. I am having problems bleeding my brakes. It looks as if I'm getting all the air out and then I start my blazer and i have no pedal pressure. any help would be greatly appreciated.

so lean it out. it will run better, and you'll use less gas.

Yea, it makes no differance as the power assist sysems do just that (assist you if pushing the peddle with less effort). It has nothing to do with the actual hydraulic portion of the brakes. Therefor it doesn't matter.

The Whole Post. PM me and I will email the pics if you have problems seeing them. Post 16 has pics.

Another post regarding brake issues Bad MC

Brake Issue 2.

I had what you described last month after swapping axles. It was a bad MC. Bought a new MC, bench bled it, bolted up and 10 minutes later with pressure bleeder, all was good.

The MC was fine when I started an axle swap, but probably toasted it during the bleeding. (old and brittle o-rings inside)[/FONT]

Well, I purchased a "Mighty Vac" from harbor freight and it worked awsome!! Brakes are much better and stop pretty good. Now that the extended lines are on, I gotta find a place to see how much this bitch flexes Oh yeah, also want to see if these new 35's will rub with my 4" procomp lift!

Looks to me like you've got a built-in ramp right there next to the truck.

Your so right, but i already thought about that one. The bottom portion of that ramp has fallen apart, i think my neighbor would be pissed if the whole wall came down
