Genuine Porsche Brake Booster Check Valve

The Genuine Porsche Brake Booster Check Valve is an OEM power brake booster check valve (also called a vacuum check valve or brake booster vacuum valve). It is engineered to Porsche factory specifications.

Key Features:

• One-way valve design lets engine vacuum reach the brake booster and blocks it from flowing back
• Helps the booster hold stored vacuum when the engine is off or when manifold vacuum drops
• Supports consistent power-assisted braking and pedal feel
• Genuine Porsche OEM part, built to factory fit and quality standards

A worn or leaking check valve can cause a hard brake pedal, reduced power assist, or a vacuum leak that affects idle quality. Replacing it with a genuine Porsche valve restores proper brake booster operation and gives you OEM durability and a precise fit.
