Understanding the Cayenne Brake Pad Warning System
The brake pad warning light is part of your Cayenne’s sophisticated braking system, designed to alert you when the brake pads are nearing the end of their lifespan. This system typically consists of sensors embedded within the brake pads themselves. When the brake pad material wears down to a certain point, these sensors trigger the warning light on your dashboard. Ignoring this light can lead to further damage to your braking system and compromise your safety.
