Brake System Bleed

Anyone have a good system for bleeding the brakes? I have never done a brake system bleed before and I'd like to do it right the first time. Thanks!

* I read the write up on 7point3.com but it wasn't completely clear to me how you get the old fluid out and the new stuff in...

Re: Brake System Bleed

I've had to do it a few times on mine. Not sure about the Superduty with the hydroboost but I don't see how it would be much diffrent. Trick is to get 2 people & loosen the bleeders up. Have one guy sit in there & pump the brake pedel all the way to the floor & keep doing it. The other guy keeps watching the lines for fluid & bubbles. The key thing is to keep pumping them until there are no more bubbles & then have the guy in the cab give the pedal one good pump & hold it while the other guy tightens the bleeder screw up. They might be slightly soft (not as firm as usual but still work good front & rear) but will usually firm up after a day or two of driving. I know mine always does. If not get another guy to help out & bleed em again.
& in case your wondering I do this when the truck is shut off.

What do you mean by Program, what is it & how do you do it?
I'd really like to know more about it.

I am still confused, I get my brother, we loosen up the bleed screws aaaaannnnddddd..... Do we hook up hoses to anything? Where am I looking for air bubbles at? Where does the new fluid go in?

Re: Brake System Bleed

old way -

get a small box wrench that fits the bleeder slide it on
get a clear tube that fits the bleeder nipple , put one end in a large jar/ with some clean fluid in the bottom, hose must reach the bottom or at least be under fluid.. (so air doesn't get back in)

make sure brake res is full, and the cap is off, so you can add more fluid if needed so keep some handy.

have buddy sit in the drivers seat , and make sure you can talk back and forth .

have him slowly depress pedel and hold it down , you crack open the nipple,
and bubbles should come out. (you will see fluid come through the hose with small train of bubbles go by)

then you tighten nipple, say release, he lets the pedal come up.

you say go he presses, you loosen,........do this on all 4 corners.

becareful the res doesn't drain , or it will let air in, don't overfill the catch can either or reuse the fluid, or spill any on anything painted .


or...you could go to the auto part store/ sears and get a one man bleeder.

well that's my 1/2 cent lesson anyway.

I never hook up hoses, you'll make a mess if you don't. Oil dry or kitty litter will clean it up. Just watch for the fluid & bubbles to come out of the bleeder screws. You may have to top off the fluid at the master cylinder under the hood. It's the thing with a small little clear tank that says brake fluid in case you didn't know. Don't just pump the brakes, see a few bubbles & call it good. You will probley really have to bleed them things out good so just keep pumping & topping off the master cylinder.
YOU CAN DO IT!

I thought that was where you were supposed to top off the tranny fluid???

Re: Brake System Bleed

its a program on most diagnostics equipment that you plug into your obd 2 port. it cycles your abs to get the air out. like i said if you dont know anyone that has the equipment to do this just make the abs engage.
