Description
This is a dual line brake master cylinder for a Mini 1977 to 1989. During this run of cars there were four different styles of brake master cylinders. This cylinder was the lastest style but there are some differences that you will need to check. The GMC227 metric fittings (top is 10mm and the bottom is 12mm) with the bottom port feeds the rear brakes and the upper port feeds the front brakes. If you Mini has the same size ports you will need to purchase a pipe conversion kit to update them to the two different size pipes. BAU5655 or LK17049 Replace your leaking cylinder with this new unit before yours leaves you somewhere you don't want to be. Cross Reference LM15121
