★ High-quality copper gasket ensuring reliable sealing of the brake system. When replacing the master cylinder or outlet fitting, it is recommended to replace both gaskets (637604 and 637606) to guarantee a completely leak-free connection.
Installation notes
When fitting the master cylinder outlet fitting, two different gaskets are used: 637604 and 637606. Replace both gaskets simultaneously for optimal sealing. The copper crush washer must be slightly compressed during fitting to guarantee a proper seal. Tighten the fixing bolt (637605) to the correct torque to prevent leakage.
Historical context
The Wagner Lockheed master cylinder with Y-outlet fitting distributes brake fluid to the front and rear axles via two separate brake lines, a reliable system that served military vehicles for many years.
