About This Product
When the front brakes on your dual-disc Harley start to feel wooden or the master cylinder begins to leak, this 11/16-inch bore replacement from MCS is the ideal fix. Finished in a clean black, this handlebar master cylinder is designed specifically for 1985 to 1995 models equipped with dual front discs. The 11/16-inch bore provides the correct hydraulic ratio to move enough fluid for two calipers, ensuring a firm lever and reliable stopping power. It is a direct replacement for OEM part 45013-85C, offering a factory-style fit and finish that integrates perfectly with your original controls.
Manufacturer part number: 508001.
