Text excerpt from the catalog:
Complete repair kits for stock style 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 on the underside of the master cylinder.
