Austin Mini Brake Master Cylinder For Built In Booster After 88-
One of the brake master cylinders used on some of the later model Minis is a GMC242, now GMC90376. If you decide that rebuilding it is the best option, then this seal kit includes all the internal rubber bits you will need to do the job right. Very inexpensive compared to the price of new master cylinder!
