discodawg Posted May 22, 2011 Report Share Posted May 22, 2011 I have a 1992 Beta Zero and I am trying to find a front brake master cylinder rebuild kit (or even just the seal) -does anyone know of a supplier? I have tried the UK Importer but am advised the part is obsolete.The cylinder is a Brembo and is marked 10.4773, and the seal measures 10mm.any help would be much appreciated.

zerogara Posted May 29, 2011 Report Share Posted May 29, 2011 Seals are like bearings, they have three dimensions inner outer diameters and thickness, but there maybe quality differences as well. For hydraulic fluid or motor oil, hydraulic ones wear happens in and out instead of rotating, etc. O-rings inside the piston/shaft are important for rebuilding and rarely you need a new piston if it is severely corroded. I would search for a 10mm master cylinder from a dirt bike. Maybe a ktm or husqy that might have a compatible fitting for your brake line. It may be a cheaper/easier solution. Some of the mottard conversion make people change the whole front brake system and nearly new systems sell dirt cheap. If you do find a source though please let us know here as well.
