TT250 odd front brake issue

'16 TT250 · 08-18-2016, 09:07 PM

When the bike sits for several days or weeks the front brake doesn't work 'till I pump it a few times. Never experienced this on another bike, and I've had plenty. I've had a few that would do this with the rear brake, some that even had to be bled; I assume because the reservoir is close to the same level as the caliper. SV 650's seem to be high on the list for the rear brake doing this.

The TT's reservoir looks to be completely full, no bubble in the sight glass, which would leave little air space so maybe temperature changes are creating a vacuum or something.

Not trying to solve it, just thought I'd mention it in case someone else has the same issue they won't feel alone. If I decide to address it and find the cause I'll post it for others.
