【Save Your Time】 A 1.1liters capacity reservoir allows you to change the whole fluid of the brake system in one go (including 4 slave cylinders) 【One Person Operation】 Use a compressed air supply thus no need for another person to pump the pedal. The 1liter refilling bottle ensures the master cylinder reservoir is topped off. Plus hanging hook and locking trigger allow hands-free operation. 【Cleaner Quicker and Quiter】 Drain the old fluid into the collection reservoir directly so as not to spill out and mess up everything anymore. Also, an integrated silencer makes your working environment better. 【Durable & Light】 All the components of this bleeder are reinforced material to adapt to the light corrosion of the brake fluid. The whole air gun is crafted with aluminum alloy and covered with a TPR grip, which features sturdy, lightweight, and ergonomic. 【FIRSTINFO ASSURANCE】 MADE IN TAIWAN is our pride, and we guarantee premium quality without a premium price.
