Replaced clutch master cylinder, now clutch does not operate

[aseigler]

Working on fixing the basics on a new to me 2003 Valkyrie standard.  The clutch master cylinder was missing the ear that the mirror threads into and aftermarket mirrors were added, too far to center for me, so picked up a complete new one. Here is what I did:

Code:

1.  Remove old clutch master cylinder lid, syringe out all fluid
2.  Remove clutch lever, and detach the two electrical connectors from the switch
3.  Remove banjo bolt and washers
4.  Attach banjo bolt to new clutch master cylinder
5.  Attach new clutch master cylinder
6.  Fill reservoir with fresh brake fluid
7.  Attach clutch lever and electrical connectors
8.  Crack bleeder valve with 10mm socket
9.  Setup to bleed with 10mm box end wrench and length of clear turbing
10. Lever in, open bleeder, close bleeder, lever out

Repeat #10 so many, many times. Repeat #6 as needed. This seems exactly like bleeding brakes on a car but with everything closer together.

Lever goes in with almost no resistance at all, virtually no pressure is built. Clutch is not operational whatsoever.

Where did I go wrong, and how do I correct this?

Thanks,

You might have a big slug of air in the line. If you have a Mighty Vac, connect it to the bleeder and draw fluid down from the Master Cylinder (MC), while keeping the MC full so as not to draw in air. Once you get a relatively solid system you may get a firm clutch handle. Then bleed it as before.

If you still do not have a firm clutch lever, make sure the bleed path is clear under the little tab in the MC. If all that fails maybe the seals in the MC are leaking by.

I picked up this thing: https://phoenixsystems.co/products/v-5-diy-reverse-one-man-brake-bleeder

Hooked it up like the instructions said, loosened the MC body and slid the MC to the right to get it level, then pumped the brake fluid backwards through the bleeder until the fluid hit the mark. Put lid on, moved MC back to proper location, unhooked everything and it works fabulously. Very quick, very easy.

Where has this thing been all my life? Now I am going to have to bleed the brakes on everything I own.

Nice.
