    Master Cylinder Repair Kit, 17mm 76-80

    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. If you are lucky, all you will need is a repair kit to revive your master cylinder. For best results, hone the cylinder with a flex hone of the appropriate size. If the pitting is too deep, a good local machinist can insert a stainless steel sleeve and save the part.

    There are 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.

    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.
