General information about this item

Product info
The groove seal 5-0790 (B6-06-0195) for ATE master brake cylinders reliably seals the piston in the BMW Isetta’s brake cylinder against the brake fluid. Aged or cracked boots are a common cause of leaks and pressure loss, which is why replacing them should be a central part of restoration work during every brake overhaul. This restores the function and safety of the original brake system in the long term.
