About This Product
This front caliper piston assembly is designed for Harley-Davidson models equipped with dual front disc brakes. It is a vital component for maintaining braking performance and safety. This assembly fits 1980 to 1983 FXWG models, 1977 to early 1978 FXS models, and early 1978 to 1983 FX, FXR, and XL Sportster models. It is a direct replacement for OEM 44157-77. If you are experiencing sticking calipers or fluid leaks, replacing the piston assembly is the best way to restore the responsive braking feel your bike had when it left the factory. Precision-engineered for a perfect fit, it ensures consistent pressure across your dual disc setup.
Manufacturer part number: 909420.
