OK... been off here for a while due to some serious health issues while in grad school... So, did a front brake job.. my first ever on ANY of my 8 bikes I've had. Bike only rider.. no car anymore... Anyway... all seemed good. Brakes seem good. No jittering... not vibration. No squeeks. However, past few weeks, noticing that soft "ssssh... ssssh... ssssh.... ssssh" sound... so pad is in contact with a rotor... Is this bad? Something I need to fix? No idea. I cleaned everything pretty damn well when I did the job. Just need to know what this is, how bad it is, and what to do? God knows, the next 4 weeks are literally the busiest time of my entire 51 years... I have every hour charted and accounted for for next 4 weeks to get done what I have to get done with no time to even rest one hour... so, I really need to just ride this for another 2k... or come up with the scratch to pay the robbing dealer here to fix it... they wanted double the price of any tire I wanted... so God knows what they will want to just adjust my damn brakes... probably $250.
