    Anyone have a contribution for procedure of brake bleeding on the front end? Just seems that I'm not getting maximum brake on the front end no matter how many times I do it. Sometimes I get a good, full lever, and other times it feels mushy.

    Help me bleed.....?

    I used to use the forearm pump method but I started doing it another way.
    There are currently two schools of thought, push and pull. Pulling fluid down has worked well for me and I have not tried the new Phoenix Systems push method but I hear it works sweet.

    Pull method

    What are you using for the pull method? Is it a typical vacuum pump on the bleeder?

    Bleeding

    I had the same problem with a Performance Machine cylinder and caliper on a custom bike. I eventually got it by pumping but it took a whole lot of pumps for it to finally bleed. Afterward, someone told me you can use a large syringe with a tube attached to the bleeder screw and suck it down a few times. I haven't had the chance to try it yet but it may be a cheap alternative if you can get access to a syringe. Good luck.

    Whoda thunkit!

    Yeah! I'd have never thought of it! You can get the large syringes at an animal supply store. I guess you can hook up a bit of fuel line to connect to the bleeder. Thanks for the "econo-solver" ! I'm gonna give it a try, and I'll get the results back to ya'll afterwards.

    You can get a pretty inexpensive vacuum bleeder at any parts store like Checkers, Pep Boy's etc. They work very well as does the syringe.

    Air Bubbles

    Also bikergim1, an old trick to do after you get most the air out: it's an overnight trick, but works real well. All you have to do is tie or wrap a string / bungee cord around your brake lever. (as if you were applying the brakes) not too tight, but snug. Overnight or several hours later the bubbles will magically seep up to the top (master-cylinder) works on the rear brake as well.
