The little brass threaded parts?

I looked for weeks and never found anything quite right. Bleed screws don't generally go smaller than M6 thread, and you need M5 for Avid calipers. Get a cheap kit like the Red Dog Racing ones, or better still treat yourself to an avid one and feel smug after your third brake bleed…you will now be better off than if you took it to your LBS.

If you must, there are instructions somewhere on threading your own plastic tube fittings. This seemed to work at first, but they are not very robust and leak somewhat too (very messy).

If you find a hollow screw to fit, don't forget you'll need an 'o' ring to make a decent seal and the head of the screw will need to be just right to make this seal…good luck !

will this work

Quad bleed kit

Judging by the section that says it will not work with Avid brakes, no.There was a post on here a few days back with a kit for about £15 that looks identical to the Avid one.

formula one? (not sure on this)
this was the £15ish ebay link from previous thread

Just tagged it as "avid bleed" if you want to search for it, original item now sold, but similar item with different clamps being offered for £17.50.
