I should have said you can tie it down overnight. Sometimes thats the best.

 

Best way to bleed is with a Mity-Vac. Sucks all the fluid through every time no nonsense.

 

As I mentioned in my first email, I have a speed bleeder and used it. I also pumped the handle many many times with no effect. I tied off the handle and will see if that has any effect tomorrow. My next step will be to go back into the caliper, pull the pistons and pre-fill that area in fluid before I put them back in. I will also see if I can pre-fill the fluid channel before putting it back on the fork.

 

I also use the mighty vac, but you have done everything I can think of. No experience pre filling calipers never had to. I would be thinking there is a air leak somewhere

 

If I'd done all that to the caliper, I might start to suspect the master?

 

I'm with you. I would start at the master cylinder. Make sure fluid is pumping out of it first.

 

you've air in the lines, and it's rising faster than you can push it down.

Bleed at the banjo fitting on the master cylinder. It's messy, and protect the paint, though if you're running silicone fluid, it won't blister the paint.

Easiest way is to pull the lever, and crack the banjo fitting. You'll hear the air escaping with a snap/crackle/pop sound. Close the fitting, release the lever. Repeat until no more air comes out. Then bleed the calipers in the normal manner.

 

If the air was rising in the line, then it would surface in the main reservoir. I believe this is why a couple of people have recommended that I leave the brake handle pulled tight for the night to allow the escape at the reservoir.

In any case, I have run a couple of bottles of brake fluid through the lines with the speed bleeder until there are no bubbles at all. I believe that I removed all of the air in the line. Late this evening I found some fresh fluid leaking at the bottom of the caliper. I think that the problem might be there. I'll take it apart again tomorrow night and see if I can find the problem.

The only other thing that I can think of is the handle connection itself. I have not taken it apart to see how it connects to the reservoir and pumps the fluid. Maybe there is a disconnect there that prevents it from pumping properly.

 

I am a big fan of the Mity Vac, however, one must remain mindful of how much to pull thru at a time as to keep fluid in the reservoir.
Best wishes to the OP, I hope you find your brakes, no one should have to ride Flintstone style.

 

I too like my mity-vac, but these days I use a syringe and rubber tube.

Fill the syringe with fluid, attach to the caliper, open bleeder, push fluid and all air bubbles up to the master cylinder.

Quick, no pumping, no waiting, 100% bled every time.
