These diaphragms perish and crack with age, letting air and moisture into the fluid reservoir. Renewing them is a simple, low-cost way to keep brake and clutch lines free of air and prevent fluid contamination - a very common service item on older Goldwings.

Please verify fitment against your specific year/model before ordering. Shipped from Portugal.
