DescriptionBrake Cam, frontfor Vespa 125 GT/GTR/TS/150 GS/VGLA/B/GL/Sprint/V/180-200 Rallyl 45,8 mmØ 13 mmsteel, zinc platedPRODUCT DESCRIPTIONBrake cam. Actuating mechanism for the drum brake pads. The drum brakes are actuated mechanically. The parts involved are the brake lever, or the brake pedal, brake cable, lever, shaft and brake cam. The brake cam sits between the brake pads and forces these towards the drum when braking.Replacement for worn componentsOptimum brake performanceOptimum modulation of the brakeWhen actuated the metal of the cam rubs on the metal of the brake pads. As a result the cam tends to wear over time. Copper or high temp grease makes the cam last longer, but even if the brake was always meticulously maintained there will be some wear after years and years of use. Once there is an edge worn into the cam this will not only affect braking power but also modulation. Ideally you should be able to finely adjust, or modulate, braking power with the lever or pedal. If, for instance, the rear wheel locks up you should be able to reduce pressure on the pedal slightly and in a controlled way to unlock it. With a worn cam it is possible that even though you reduce the force on the pedal the wheel stays locked because the cam is stuck and cannot be pushed back by the brake shoe return springs. It only unlocks when almost entirely releasing the pedal. With brakes in particular everyone should be aware that all components should be in the best possible condition, not matter what. Hence SIP recommends you check your brake with all its components regularly and replace things that are in less than perfect condition.OEM numbers (for comparisons): 41586 - 18039 - out of production (PIAGGIO) 41586 (MOTOVESPA)Model / manufacturerccTypeEngineYear of constructionAdditionMOTOVESPA 150 GS15004C2T AC1967MOTOVESPA 150 S150VTT2T AC1962MOTOVESPA 150 S150V13502C2T AC1964MOTOVESPA 150 Sprint15004C2T AC1966MOTOVESPA 160 / GT16009C2T AC'68VESPA 125 GT / 125 Sprint125VNL1-22T AC'61-'73VNL2T 30001 ->VESPA 125 GTR125VNL2T2T AC'68-'78VESPA 125 TS125VNL3T2T AC'75-'78VESPA 150 (T4/150) (D)150VGLA-B2T AC'59-'65VESPA 150 GL150VLA1T2T AC'62-'64VESPA 150 GS (D)150VDTS2T AC'56-'65VESPA 150 GS150VS1-5T2T AC'55-'61VESPA 150 Sprint150VLB1T2T AC'65-'74VESPA 150 Sprint Veloce150VLB1T2T AC'69-'79VESPA 180 Rally180VSD1T2T AC'68-'73VESPA 200 Rally200VSE1T2T AC'72-'79
