Make sure he realizes he cannot quit pushing the pedal or let it move up any until after you have closed the bleeder. (didn't state how old he was, not sure if he might be too young to know that)
I've never pumped the brakes while bleeding them, not sure if that would make a difference or not.

See I was doing it wrong!!!!1 Damnit!!!

I have a 91-92 Haynes, 91-98 Haynes, 1991 Dealership/shop repair manual, and lastely a 1991 Electrical Vacuum And Troubleshootig Manual. In one of them I swear it said to pump the brakes in between bleeding to force more fluid down the line. Crap they may have been something I read for when I was exchanging the brake fluid to make sure all old fluid was removed.

Oh and my son is a very precoscious 8 yrs old. He does exactly what I tell him to do, unless he knows better then he will debate it with me. hahahaha

Ok so I will try Yob's method, but my co-worker is telling me they are the same and that the only difference is that pressure is applied b4 bleeder valve is opened. But I was also thinking that maybe my son wasn't pushing hard enough.

See that was why I bought the vacuum bleeder so I could do it by myself, but apparently I can't read simple instructions and operate the bleeder right.

I also was told by an old mechanic that I could get a resevoir cap with a tube top. Get a gallon container of brake fluid with a pump top. With the container and hose connected to resevoir cap pump the gallon container which would pressurize the system and ensure that resevoir stays full. then bleed each wheel and keep the gallon container pumped to maintian pressure in the brake system. It forces the air out and ensures that the brake lines are full. I can also go over brake lines and search for leaks. Anyone ever hear of this? I didn't want to say anything to him, but wouldn't I be forcing air into the system as I pumped the gallon of brake fluid???!!!

I think this is similar to what your mechanic is suggesting.


I have a vacuum pump type bleeder similar to the one that you show in the picture. The problem I had with it was that air can leak around the threads of the bleeder screw when you open it up and you end up with air in the system.

Well I thought I might update this. I am planning on building one those pump bleeders.

I got into the front brakes and found that my hub was broken and then when I pulled off the rotor I discovered that my inner wheel bearing was completely gone and I had no sign of a wheel seal. The rotor was wobbling and the rear pad was stuck against the rotor.

I am assuming that this is the main cause of my brake pedal being spungy. A co-worker had told me to check the front pistons. I kind of ignored him since the front and rear are on seperate lines. But there might have been something to it. If my calipers in the front are maxed out then would I get enough pressure in the lines to actuate the rears? Well its a thought. I am working on the fronts now and hopefully all will be well when they are done.
