Volker (vps3922) and I were cruising in 3205 after 6 months of storage and we could smell burning brakes.

The front left rim was hot to the touch. Turns out the caliper was frozen up even after flushing the system before winter hibernation.

One piston came out fairly easily. The other.... not so much. Had to put it in a vice and use a vice grips and a rubber mallet for a few hours until I got it out.

New pistons, rebuild kit and braided soft lines ordered.

Put a pressure tester on the cooling system and found a leak in the VOD. This after a cooling flush and test in the fall too. Looks like I have a long weekend in front of me. Goes to show even with regular maintenance these cars still need tlc.
