    Master Cylinder Repair Kit, 16mm 74-75  are No Longer Available!

    However, we do carry 17mm Master Cylinder Repair Kits.  If you have a 16mm master cylinder on your 1974 to 1975 classic BMW airhead we would suggest having the master cylinder bored out to 17mm and then use the 17mm repair kit listed below.


    The old ATE master cylinders, being out of sight and out of mind under the fuel tank, were often neglected. They are made of cast iron and susceptible to corrosion.

    There were three sizes. The size should be stamped on the body of the master cylinder. Locate that before ordering to ensure that you get the correct kit.

    The 16mm was Equivalent to BMW part number 34 31 1 234 925

    Not quite right for 1977 R75/7
    The O-ring that goes between the master cylinder and brake reservoir is not the right part. The O-ring in this kit has an inner diameter of 12mm but my master cylinder groove has an inner diameter of 18mm.

    old beamer brakes
    This rebuild kit for my 74 R90/6 is priced right and delivery is excellent. Quality is as expected of BMW.
