SRAM Force 1 Bleed issues

Hi all,

I am trying to bleed my SRAM Force 1 brakes. I have the Epic Bleed SRAM kit and also a EZmtb kit. Neither of these kits seem to have the correct fitting for the calliper end bleed port.

It looks to be standard across the red, force and rival, but the port leaks when I try and screw in the fitting supplied with the Epic Bleed Kit

Anyone have any idea what adaptor I might need?

    That looks like the correct fitting for Force 1. Are you able to get photos of your actual caliper and the fitting?

    There looks to be a thread, small o-ring and then the port tapers inwards. The epic fittings don't seem to have this taper so the o ring on the epic bleed adaptor cant get far enough down to make a seal.

    This is from the Park Tool website. The adaptor looks to have a taper to the end.

    I've just looked at a Rival caliper and it looks the same, and I know the Epic kit works with that. I screwed an Epic fitting into it too and it looks the same as in your photo, so this should all work. Does it leak throughout the bleed or just at a certain point? How much does it leak?

    It leaks as soon as I start pushing fluid up, pretty badly. The o ring on the epic kit doesn't seem to seal against anything as it doesn't screw in far enough. There looks to be a small o ring at the bottom of the female thread of the calliper but not sure this is doing much to seal.

    I will give it another try this evening

    The o-ring on the Epic kit doesn't reach the caliper on mine either. The only thing I can think of is there might be a bit of grit or some damage to the threads which is stopping it from going in all the way.
