Mk II sedan + others, sometimes found on 3.8 + 3.4 Jaguar Sedans.
This booster is easy to recognize as it has an auxiliary 5" hexagonal vacuum diaphragm assembly attached to the servo.
This booster works very well with dunlop disc or drum brakes, some aftermarket boosters tend to over-boost.
*Please specify disc or drum brake cars as valving is specific to application.
We will give you back $100 for your old cylinder if you wish to return it.
