Brake Rebuild - Seized Piston Extraction XS750

Extracting 42 yr old seized pistons can be a real challenge. We illustrate how to extract pistons using the rear brake as a hydraulic pump. After Extracting the pistons, we polish the pistons, clean up the calipers and rebuild the system. Parts used for this project:
