Hella 008570021 Electric Brake Booster Vacuum Pump

The Hella 008570021 is an electric vacuum pump designed to provide vacuum on demand for brake booster systems in Audi and Volkswagen vehicles. This auxiliary vacuum pump ensures proper brake boost operation when the engine cannot generate sufficient vacuum through the intake manifold, particularly during certain driving conditions or with modern engine designs.

Key Features:

• Electric operation at 12 volts DC with integrated relay for reliable performance
• Rotary vane compression principle for efficient vacuum generation
• Three-pin electrical connector for straightforward installation
• Maintenance-free design with dry-running, self-lubricating operation requiring no oil system connection
• On-demand operation reduces energy requirements and helps lower CO2 emissions
• Direct replacement for OEM part numbers 1K0612181F, 1J0612181, 1J0612181B, 1J0612181C, and 1J0612181D
• Low noise emissions during operation

This vacuum pump operates on a simple on/off principle and is not designed for continuous duty. The pump contains an eccentric rotor with sliding vanes that compress air volumes to create vacuum, drawing air from the brake booster through the pneumatic brake lines. Engineered to OEM standards, this pump ensures consistent brake performance and enhanced vehicle safety. Professional installation is recommended.
