Refill of brake fluid on Type 2 08/72-07/79 is executed through a reservoir near the front passenger seat. There is a connection through this reservoir with a second reservoir that is located above the master cylinder. The connection between these two reservoirs is effectuated by a PVC brake line which we have taken now into our assortment. This PVC brake line can get damaged by manipulation or friction with other parts of the body. Available each from stock.
