The VW Lower Brake Fluid Reservoir installs at the top of the master cylinder, pressing into the rubber grommets at the top of the cylinder. The two ports to the master cylinder are 100mm (3 7/8") apart, center to center. The reservoir has a single inlet which points straight out the front and supplies the reservoir. The brake fluid reservoir is a direct replacement for 1971 through 1972 Type 2 Bus models.
