Features 1Brake bleeding is the procedure performed on hydraulic brake systems whereby the brake lines (the pipes and hoses containing the brake fluid) are purged of any air bubbles. This is necessary because, while the brake fluid is an incompressible liquid, air bubbles are compressible gas and their presence in the brake system greatly reduces the hydraulic pressure that can be developed within the system. The same methods used for bleeding are also used for brake flushing or purging, where the old fluid is replaced with new fluid, which is necessary maintenance. 2This brake fluid bleeder is made of ultra-sturdy plastic, which features anti-corrosion performance and guarantees a minimal maintenance for lifelong satisfaction. 3This brake fluid bleeder can absorb an unpressive 3L of liquid and works with all car with 42mm threaded hydraulic fluid reservoir caps and suitable for most European models. 4Sturdy plastic material makes it not only easy to clean, but also suitable for easy brake bleeding on a wide variety of vehicle types to maximize their brake performance for safe driving experience. 5Professional manufacturing, quick, clean and efficient, single handed operation.
