It pairs a reinforced 3-liter pressure tank with a clear 1-liter catch bottle, four master cylinder adapters to suit many vehicle makes, and a pressure gauge plus relief valve so you can work accurately and without a helper. The kit is designed for repeat use and a tidy workspace, with thickened seals and spare O-rings included.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this kit let one person bleed brakes safely?\u003c\/h3\u003e\n\u003cp\u003eThe Cupbunny kit pressurizes fresh fluid from the 3L tank through the master cylinder, forcing old fluid and air into the 1L waste bottle while you control pressure and flow alone. A built-in gauge and relief valve prevent over-pressurizing, and a secure adapter seal minimizes splashes.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e3L pressurized supply tank for continuous fluid feed\u003c\/li\u003e\n  \u003cli\u003eReadable PSI\/Bar gauge for maintaining recommended pressure\u003c\/li\u003e\n  \u003cli\u003ePressure relief valve to release system pressure safely\u003c\/li\u003e\n  \u003cli\u003e1L catch bottle with hanging chain to collect waste fluid\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich vehicles will the master cylinder adapters fit?\u003c\/h3\u003e\n\u003cp\u003eThe kit includes four precision-sized adapters to fit a broad range of master cylinder openings.
