Hi,

After bleeding my brakes yesterday I gave them a quick squeeze to make sure the bite had returned, I then noticed some "bubbles coming from the side of the cap.

Is this normal? as I thought bubbles would be bad as you'd want to keep air out of the cylinder?

Cheers for any light shed on the matter :)

    which "cap"?

    bore cover?

    lever assy cover?

    or...

    I don't think it's a problem - get the same thing with my old M4's.

    I think the bubbles are just air being forced out from behind the rubber seal thingy beneath the cap.

    As long as there's no fluid coming out ... :)

    not really an issue as there is no pressure under the diaphragm.

    also when rolling the diaphragm you do tend to get a bit of fluid on the joins and this can cause a bubble to form at the breather hole.

    Yes, as noted above it is no problem.

    Just wipe off the excess fluid and rinse with water.
