Mikey,

you've done the old 'put new brake lines and drain the system completely' trick haven't you.

As you've discovered you can pump forever and get nowhere (story of my life.....). The trick is to 'suck' fluid down to get something into the system to work with.

2 options -

1 either borrow the specialist tool which creates a vacuum and drags brake fluid down

2 get a long piece of clear plastic pipe and suck - you will note the word clear here - until you get fluid through. do for both calipers and then you should have enough in the system to bleed as normal.


HTH..............Chris

Oh and I'm sure others will be along shortly with better and more ingenious ideas on how to do this.

When I had similar problems with my system one club member suggested loosening the banjos progressively downwards and pump the lever until fluid oozed out from the joint, then retighten moving on down the joints. I found this worked but you need to have rags handy to catch the leakage and plenty of fluid.

If once you clear the main bubbles out of the system and if it still seems a bit spongy try tying the lever back to the handlebar and leave overnight. Works wonders in removing any stubborn air.

Mikey Babes,...................
Undo calipers, raise em higher than master cylinder & bleed em, that way the air will rise & bleed out! Alternatively, lower lever/master cylinder! :wink:
