Hi everyone. Last month I was out for a drive with my 360 when I realized that the front right caliper (well at least one piston I would say) seized in the closed position. So, bad smell of brakes and of course the front right brake overheated. It overheated so much that the heat melted the wheel plastic center cap: After removing the wheel I was able to separate the pads from the caliper and so I could drive (carefully) back home. Once home I took off the caliper in order to inspect it, and this is what I found: As you see one of the dust seal was in pretty bad shape. I then decided to have all four calipers repainted and completely refurbished. The company that did the job said that apart that bad dust seal everything looked in not so bad shape. I put them on the car today, fitted new pads, and then bled the system using my pressure bleeder. Everything went smooth as usual, except the front right. It's simply impossible to bleed it. Nipples open, pressure in the system, but nothing. I tried also the old fashion way pumping the brake pedal but it feels heavy, like the nipples are still closed. And the pistons are not moving at all. All the other three are working normally. I bought the car 2 and a half years ago and it had a full service before delivery, brake fluid included. I checked the reservoir in my pre-purchase inspection and was super clean, with nice and fresh fluid. It was the same now that I installed the refurbished calipers. Any ideas? It's several years that I'm doing maintenance on my cars, but 've never seen something like that before. It's frustrating, because a brake system is something quite simple, and I have no idea how to solve the issue..
