This rubber is located in the master cylinder where the brake line grommet or reservoir is attached. Weathered rubber will cause leaks and/or attract moisture, eventually affecting the entire brake system.
These rubbers are not supplied with every master cylinder, we advise you to always order this rubber and not to reuse the old one.
If several qualities are mentioned, quality A is identical to the original in terms of design and rubber composition and quality B is a reproduction. On quality B we cannot guarantee a long life, which is the case for quality A.
Note: All years of construction and use specified are those of the factory delivery; if a replacement (after-market) master cylinder has already been fitted, this may be different. Always check the dimensions before ordering, the dimensions mentioned are those of the rubber and not the hole of your master cylinder, sleeve, brake line or reservoir.
