Hello Bob: I have a vehicle that I worked on yesterday and completed today. No, you may not ask what one, for you may stop reading this. During the year, the brakes work fine and stop on a dime, but when I park it for Winter, about November, and try to move it in March, the Rear Brakes are always seized. Not the single front one. (oops, cat's out of the bag). This has happened the past three Winters. I have to release the tightening adjusting screw which open/closes, the rigid end of the shoes. It always takes about three full turns. I never need to readjust. They are not self-adjusting. I just yesterday took all the parts apart, washed in cleaner, and reassembled, flushed out the lines, slaves and master, cleaned the reservoir, all with ethanol, blew it out with air and let dry overnight. and today replaced with Dot 5 fluid. I have no idea if this is going to fix it, I won't know until this time next year. Brakes work now as good as they ever did, but will they last next Winter? You can read all about this process in this coming up issue of Conveyancer. Later, Ian.
