• Ok so I just got the pistons unstuck and bled the v-twin brakes I got from spotter. First time working on hydraulics, seemed easy enough. Rolled the diaphragm back on like in the instructions but afterwards I noticed a wheezing sound like air escaping when working the brakes. Put some soapy water all around the MC bits and like in the picture, bubbling around a small vent or channel in the lid, when pushing the pistons back in. Wtf? Normal?

  • Should be explained by fluid being pushed back in to the reservoir. As it does so the diaphragm bulges out and pushes air under the cap out through a vent.

  • Sounds right Howard, thanks a lot. I arrived at the same conclusion late last night, the noise suddenly became audible because of the excess brake fluid in the vent. I expect it'll go away eventually.
