    Have someone help you. Start on the rear pass side and have them push the pedal and you open the bleeder. Close the bleeder and have them let up and push again. Repeat as many times as you wish until no air comes out and clean fluid comes out. Then do the same the dr, pf, and df.

    or you can use some talent and use the power seats and a 2x4 to push the brake while you bleed....wad up

    REDNECK!!!!!!!! LMAO

    Motive Products makes a great pressure bleeder. Brake bleeding and flushing the system takes about 4 minutes.

    Rednecking works when you are by yourself.

    I pulled out my power bleeder on Friday and there's just nothing like it. Absolutely one of the better tools in the universe.


    If Dave feels 60% throttle is 100%, what does he tell his wife.

    How much are the power bleeders? I'll probably just do what dsmuts said and have my little brother help...it's gonna be his car anyway....

    There are little bleeders on the abs module you could try and bleed those.

    Did you start at the rear right wheel and pump it a ton of times, then the rear left, front right and front left? I usually use close to a big bottle of fluid in the process.

    If it's mushy..you still have air in the system or a problem with another line.

    I did it in that order but I didnt pump it a ton of times so yeah I think I found my problem. lol Plus it didnt use all that much fluid so I will have to run up to the store and grab some.

    We never asked why you were bleeding. Soooo why were you bleeding? If you replaced the master cylinder..it takes a bit to clear the lines and have them bleed fully. Especially one brake pump at a time.

    I'm pretty spoiled with the bleeder. It's so nice and quick. fluid flows right out and when it stops bubbling etc I let it go a little further to get clean fluid..then done. next wheel etc.

    Oh well I'm bleeding them because the other day I found that one of my lines was kinked in half. I tried to just bend it back straight but on the last tug the line snapped so I just ended up replacing the section of line with a new one from O'Reillys.

    I love it when that happens. I worked on the AC orifice tube, which had me moving the master and abs, apparently the flex lines didn't have enough because a rust spot to the passenger front opened up. Then a middle of the car underneath followed it. Really nice I say.. really fun,.

    Yeah I gotta say that these lines are a PITA! Well I'm working on two projects today and so far neither seem to be going my way. First I got the brakes on the gp and then at the same time I'm trying to replace a fuel filter in my Camaro. So hopefully I'll be able to accomplish one or the other lol

    Take a moment and do the filter. Shouldn't be too bad.

    Then bleed the lines. Overall brake lines aren't tough for me. The tough part is getting into the tight spaces to flare them.

    Ha didnt see this in time so I did the brakes first and actually got them all bled out and they work good! Only issue is the front pads are starting to make noise so I get to do those soon. But thanks for all the help! Now tomorrow I get to do that filter and try and seal up the y-pipe along with figuring out the random misfire code on my Intrepid.

    Nah it was a 2.7 but me and my mechanic swapped in a 3.5. But the cause of the problem could be this vaccum leak that I just found so we shall see how it goes.

    Haha easy there Bill.
