BMW R90S Dual Front Disc Brake ATE Master Cylinder - R75 R80 R90 R100 R100 /6 /7

1975 BMW R90S Original 16mm Dual Disc Undertank ATE Brake Master Cylinder

This is a used, original component that was not seized and in working condition at the time of removal.Please note that, due to age, a rebuild kit for the rubber components is recommended to ensure proper operation. The unit disassembled easily and cleaned up well. I chose not to repaint the master cylinder so the buyer can clearly see its current condition and finish it to their preference.

The bore does have some pitting on the bottom and I’ve included many photos for your inspection—please review them carefully. It may benefit from a light honing or a great base to re-sleeve to a smaller diameter.
