Genuine Porsche 1S0 611 377 Brake Fluid Level Sensor

The Genuine Porsche 1S0 611 377 is an OEM brake fluid level sensor designed to monitor the fluid level inside the brake master cylinder reservoir. When brake fluid drops below the minimum threshold — whether due to normal pad wear or a potential leak — this sensor triggers the brake warning indicator on the instrument cluster, alerting the driver to inspect the brake system promptly.

Key Features:

• Direct OEM replacement — engineered and manufactured to Porsche factory specifications
• Monitors brake fluid level in the master cylinder reservoir
• Activates the brake fluid warning light when fluid drops below the minimum safe level
• Plug-and-play fitment with factory wiring harness connector
• Genuine Porsche part — not an aftermarket substitute

Maintaining a properly functioning brake fluid level sensor is critical for brake system safety. A failed or missing sensor can prevent the driver from being warned of low brake fluid, which may indicate worn brake pads or a hydraulic leak. Replacing with a Genuine Porsche OEM sensor ensures correct operation, reliable electrical connection, and long service life.
