First longer distance ride on the UForce yesterday.  About half way home noticed inside of rear wheels coated with something that turned out to be brake fluid.  Not wanting to be without the unit for extended time, I filled the reservoir and bled out the system in hopes I'd find a loose fitting I could just fix and move on.  At first press on pedal fluid comes squirting out from somewhere in the caliper.  I was so hoping for a just a loose fitting.  Off to the dealer it went.  While unloading I was asked if I'd driven with parking brake on by accident.  They had previously had this issue one other time and that was deemed to cause enough heat to cause caliper seals to fail.  I had hardly used the parking brake at this point let alone driven with it on but it made me think about the quality of machine I purchased here?  The explanation seemed plausible but I'd never heard of such a thing happening before.  Anyone else have a similar issue?

Mine is the old style with a mechanical cam system on a disk on the driveline and I have run it several times with it on...long enough to toast the shoes pretty good several times. If I had the new system and made the disk glow, I'm pretty sure I would have caliper piston seal issues.
