Brake Bleeder Replacement????

Here's the deal, I have a 2001 YZ426 and I can't get the front brake to bleed and yes, I have searched all the forms... I have tried the traditional pumping, holding the caliper above the master cylinder and reverse bleeding using a surenge. I rebuilt the master cylinder and caliper, and yes it was done properley. The only reason I can figure why the brake will not bleed is due to the bleeder itself. When losing the bleeder the threads are sloppy and the bleeder moves around, do you think this is my problem??? Have you ever heard of replacing a bleeder screw by retapping??? Any help will due..

Thanks..

no fluid will come out? do u have dirt down in the bleeder

Take a look at it when you get it out.

Just clean it.

Is your brake hose pinched shut from the clamp or something.

go up top and fill master and crack the line that comes out of it to bleed and check first.

This might seem silly but it can't hurt to try. If you do have a ton of air in your system you could be pumping all day. assuming that all is well with your bleeder and nothing is pinched off, with the master cylinder full of course, try opening the bleeder and letting it sit for a bit. This method works for me every time when nothing else will. It could take possibly 5-10 minutes of standing there and watching.

But it should start to flow through the bleeder.At that point you should let it flow until half the master cylinder empties, then fill and pump the lever. It should get firm quickly.

When I said to let the fluid flow until th master cylinder empties, I meant to say let it empty about half way.:worthy::eek: Sorry. Obveously that would introduce more air into the system.
