The master cylinder plug fits into the top of the master cylinder. The plug has a hole in its center to accommodate the hard line that carries the brake fluid from the reservoir. The plug fits reservoirs used on 1950 to 1966 Standard Beetle, 1956 to 1956 Karmann Ghia, and 1962 to 1965 Type 3 (Notchback, Squareback, Fastback) models.

Master Cylinder Plug Differences


Note: The master cylinder plug acts as a seal between the brake system and the outside atmosphere. If it is damaged or worn, air may be able enter the system, which can lead to inadequate braking power.
JBugs staff member Jaime.

Our Expert's Take:

"Bloom” is a milky dusting of dry powder on the surface of new rubber products. Typically, this is caused by unused vulcanizing agents migrating to the surface of the rubber part. This is often found on new master cylinder plugs. This MUST be thoroughly cleaned prior to installation or a fluid leak will occur. Coating the plug with brake fluid prior to install can help with lubrication and a better seal during and after install.
