Compatibility notice
Check Fit Before You Buy
This version includes a 45mm threaded master-cylinder reservoir adapter.
It is designed for vehicles with a compatible 45mm threaded brake-fluid reservoir opening. Vehicle make and model alone do not guarantee fit—reservoir designs can differ by year, trim, and market.
E20 (45mm) fitment may include certain Alfa Romeo, Audi, BMW, Jaguar, Mercedes-Benz, Porsche, Volkswagen, and Volvo vehicles that use a compatible 45mm threaded brake-fluid reservoir opening. This brand list is for reference only—not a vehicle-fit guarantee. Reservoir designs can differ by model year, trim, engine, and market.
Please check your reservoir cap diameter and thread style before ordering.
This is not a universal-fit brake bleeder kit.

How to use
How It Works
- Confirm that the vehicle reservoir uses a compatible 45mm threaded opening.
- Fill the 2L tank with the brake fluid specified by your vehicle manufacturer.
- Secure the 45mm adapter to the master-cylinder reservoir and connect the pressure tank.
- Pump the handle to build pressure, then connect the waste bottle hose to the bleeder screw.
- Bleed the system according to the vehicle service procedure.
- Release pressure using the valve before removing the adapter.
Safety note: Brake systems are safety-critical. Follow your vehicle manufacturer’s service procedure and fluid specification. Avoid spilling brake fluid on painted surfaces.

FAQ
Q: What if there’s an air leak?
A: Check that the E20 45mm adapter is fully threaded and its seal is seated, then tighten all hose and quick-connector connections. Inspect the reservoir opening and adapter seal for damage. Pressurize only within the 15–30 PSI working range. If the system will not hold pressure, stop the service and correct the leak before opening any bleeder screw.
Q: How do I prevent air from entering the brake system?
A: Keep the brake-fluid reservoir full throughout the process to prevent air entry. Maintain the recommended 15–30 PSI working pressure and do not exceed the maximum pressure. Release pressure via the relief valve before disconnecting the adapter.
Q: Will this brake bleeder kit fit my vehicle?
A: This kit includes one 45mm threaded master-cylinder reservoir adapter. Please check that your brake-fluid reservoir has a compatible 45mm threaded opening before ordering. Vehicle make and model alone do not guarantee fit—reservoir cap designs can vary by year and trim.
This works like a boss and clears ok out the brake system with little to no effort!
Wow what a piece! Dida brake flush on my 2015 audi q7! No need to call for help no more!Fast n easy!TipIf you got an Audi, 2 brake bleeder screws located on each caliper.Make sure to start with an inner screw first!
This is fantastic for people who want to bleed the brake without having someone pump the brakes manually. High durability with a pressure bleed off button. The reservoir size and utility is great being able to hold a full bottle 32 fl oz with no problem. This unit works with US vehicles with Dot 3 and Dot 4 reservoirs. The pressure gage accuracy is good and very clear and easy to read.
This works great and is well built. I have seen some that posted of issues but if you make sure the brake fluid cap is the correct size for your specific vehicle, this will work exactly how it is designed. For my specific case, this solved a problem on my 2008 Mercedes E350. I had replaced a broken hard line to my rear brake and both rear brakes stopped working. I tried the pedal method and the vacuum pump method but neither solved the problem. This tool pushed fluid through with ease and pushed out all the air when nothing else worked. The product itself is well built and it required very little assembly. Great value. Would buy again every time.
This handy little device came in quite handy for a brake pad replacement and brake fluid flush and bleeding. It worked very well for flushing the entire system as well as accomplishing brake bleeding, all by yourself. Make sure to have plenty of extra brake fluid before you start the job.It is quite a simple operation, using the device to pressurize the brake reservoir on your car and push all of the brake fluid out for a fluid flush, or to extract any air in your brake lines during the brake bleed.The tool comes with a brake reservoir cap that fits most European autos, but it did not fit my Japanese Infinity auto, and not sure if it fits US made vehicles. Be sure to find out if you need a different sized cap for your car, as an air tight seal on your car's brake fluid reservoir is essential for this tool to work properly and push out (not suction) out bubbles and/or fluid by pressurizing your brake system.Watch a video or two before you start to familiarize yourself with how it operates, and make sure you have correct reservoir cap before you begin.I give this tool a VERY high rating and very happy with my purchase!
