Caliper spring, Brembo single pin front EV Jackal Centauro

Spring retainer for single pin Brembo Goldline P4 30/34 C front caliper as used on Daytona 1000, 1100 Sport carb, 1100 Sport injected, Centauro, Daytona RS, 1998-2001 EV, Jackal, Bassa and California Special. Note: Moto Guzzi parts books are confused with the part number of this spring. The parts books show this spring in the front brake drawings for 1997-2000 EV, 1999-2000 California Special/Bassa and 1999-2001 Jackal. But the part number assigned, 01659131, is in fact the spring for the dual retainer pin calipers used on later models. This 77782 spring is only for models using ONE brake pad retaining pin. Also used on numerous Ducati models, Ducati part number 000077782, fitting 916 and 748 Superbike; 600, 750 and 900 Super Sport;  600, 750 and 900 Monster.
