stripped my front brembo caliper and gave it a good clean, pushed the four piston's back and flushed all the old fluid out, cleaned up all the component parts with a spray of car wheel cleaner and an old toothbrush carefully removing all the brake dust from them and the caliper body, the pad's will go again so i dressed them with some p400 wet and dry to bust the glaze on them and scothbrited the mounting pins to get the surface rust off them so the pads won't bind on the disc, easy job, but so satisfying when you put it all back together.
