Complete set for repairing the complete master brake cylinder. Included are a piston, new seals, screws and the return spring. Especially the master brake cylinder leaks quickly when it is old or often exposed to environmental influences. Also the brake fluid itself contributes the rest and lets the piston rust sometimes. Before an expensive replacement of the complete brake cylinder, you can also try to repair it.
piston diameter: 12 mm
piston length: 49 mm
Universally suitable for many different brake pumps with square cover. Before ordering, check the shape of the cover using the picture.
