Classic Mini Brake master Cylinder Repair Kit    Suits GMC171 & GMC172 (PRE 1985)       GRK1028

Almost every Mini built prior to the dual circuit system uses a .70" bore master cylinder.

This kit fits them all.

The original size in the 1959 - 1964 Mini was  .75"  but as most of these cylinders have been replaced with the .70" size it is best to check the very early models.

Complete new single-line brake master cylinders are:

GMC171 - Plastic reservoir

GMC171ORIGINAL - Steel reservoir

GMC172 - Cooper S, Metal reservoir.
