This all-in-one Cupbunny kit combines a semi-transparent 3-liter pressure tank, a 1-liter catch bottle with hang chain, four precision master cylinder adapters, and the fittings and O-rings needed to complete a safe fluid change or clutch bleed at home. The reinforced components and integrated gauge help you control pressure and avoid spills while you work.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Cupbunny kit let one person bleed brakes safely?\u003c\/h3\u003e\n\n\u003cp\u003eThe kit uses a pressurized reservoir to push fresh fluid through the system while old fluid exits into the included waste bottle, eliminating the need for a second person to pump the pedal. A clear pressure gauge and relief valve make it easy to maintain recommended pressure and release it before disconnecting components. Reinforced adapter caps and extra O-rings reduce the chance of leaks and mess during the process.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e3L pressurized tank supplies consistent flow\u003c\/li\u003e\n  \u003cli\u003eDual-scale PSI\/Bar gauge for accurate pressure monitoring\u003c\/li\u003e\n  \u003cli\u003ePressure relief valve for safe depressurization\u003c\/li\u003e\n  \u003cli\u003eThickened tank walls and upgraded caps to prevent spills\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich vehicles will the four master cylinder adapters fit?\u003c\/h3\u003e\n\n\u003cp\u003eCupbunny includes four threaded adapters sized to fit a broad range of master cylinder caps so you can achieve a leak-proof seal on many makes and models.
