The 2020 Piaggio MP3 500 has 2 recalls, both involving brake system contamination that can reduce stopping power and raise the risk of a crash.
In one case, the brake lines can release hydrogen into the brake fluid, which weakens the lever's ability to activate the brakes. In the other, zinc plating from brake hose fittings can contaminate the fluid, requiring the rider to apply more force than expected to the brake levers or pedal to achieve normal stopping. Both issues affect the hydraulic brake system and point to the same practical concern: the brakes may not respond as expected when the rider needs them most.
