Baywindow Bus Lower Brake Fluid Reservoir - 1973-79 With Servo (85mm Pipe Centres)

This brake fluid lower reservoir is a top-quality reproduction designed specifically for VW Baywindow Buses from 1973 to 1979 that are equipped with servo-assisted brakes. Mounted directly on top of the brake master cylinder, this reservoir serves as the lower fluid supply container, receiving fluid from the upper reservoir via connecting hoses and delivering it to the braking system.

The unit features twin outlet pipes spaced 85mm apart, designed to push-fit directly into the top of the master cylinder—making it an essential component in the dual-circuit brake system found in late Baywindow models with brake servos. A proper-fitting and leak-free reservoir is crucial to maintaining reliable braking performance and preventing fluid loss or air ingress into the system.

If your original reservoir is cracked, stained, brittle, or leaking, this replacement offers a clean, secure, and OE-style fit, ensuring optimal brake fluid management and long-term durability.
