Complete repair kits for OEM and stock replacement brake master cylinders include all internal parts needed for a complete rebuild. Can be used with DOT 3, DOT 4 or DOT 5 brake fluid but you should always stay with the same brake fluid type as the three types are chemically incompatible. Bore size is usually indicated a bit out of sight on the master cylinder. When not specified for ABS or non-ABS rebuild kits fits both. Please note that kits for models with master cylinders with a remote fluid reservoir can not be used for master cylinders with an integrated reservoir and vice versa.
