Bit of a thread revival, Ive a my15 High UP and the rear brakes stick on if its driven in wet conditions the day before, so less then 24 hrs for the shoes to stick. Every morning in the winter, the shoes would bang off when reversing or moving forward (for anyone with the same issue, it sounds less damaging if you free off going forward rather than reversing first) yesterday afternoon the car was jet washed, this morning, the entire car was riding up and down to free them off - no different to leaving the handbrake fully on. I've had drum brakes on all my cars and the only time they've ever stuck was a -4 morning, when the car was washed the day before. So, question: the car is still under warranty, are these covered? I figured it was weak retracting springs originally, however after this morning 'issue' it sounds more sinister. Has there been any parts revision at all? Or anyone been to a dealer and had the issue sorted? I heard they could be cleaned, but then given the design that sounds short term, maybe my UP just cannot get wet?
