Review: Great Tool for DIY Brake Fluid Flush – Highly Recommended! - I bought this device to flush the brake fluid in my BMW 540, and it made the job easy to do by myself—no need for a second person to pump the pedal. The instructions were clear, and the build quality is excellent; everything feels solid and well-made. A few tips for first-timers: • Air Compressor Needed: You’ll need an air compressor (I used a 6-gallon one), which isn’t included. Make sure the tank is dry before use. • Reservoir Attachment: Attaching the fluid bottle to the reservoir is simple; just make sure it’s stable. • BMW Owners: If your master cylinder has a hard-to-remove dirt filter, use the included thin nozzle to extract old fluid. • Bleed Valves: You only need to open the bleed valve about a quarter turn. • Output Jar: The volume markings aren’t super precise. I put painter’s tape on the jar and marked my own levels to track how much I’d flushed. The device worked perfectly, and I flushed all four calipers (some with two bleed valves) without issues. It took about 1 liter of DOT4 fluid for the whole job. The process is slower than manual pumping, but it’s much easier and more consistent. In summary: This brake fluid flush tool is a great value and feels over-engineered in a good way. I’d definitely recommend it to anyone looking to do their own brake maintenance. Just remember to get a compressor and check for water in the tank before starting. Good luck!
Review: Great. Bring a big compressor. - Works fantastically! This makes flushing brake fluid so much easier I might actually do it! The only comment I'd offer is that you definitely want to increase the PSI of your air hose as much as you can and get the biggest compressor you can, as this is pretty "greedy" for air.

## Features

- One Person Operation: This brake bleeder bleeds and flushes hydraulic brakes and clutches with a vacuum and is simple to use. Large capacity collection reservoir can contain 2 liters of fluid, also includes an automatic master cylinder refill kit with a 1 liter reservoir (safety cup), which makes changing brake oil easy and simple for one man operation
- 2 Silicon Bleed Hoses: The vacuum brake bleeder kit includes a 60 inch silicone bleed hose with a universal rubber adapter that used with most standard and ABS brake systems, and a 60 inch master cylinder evacuation hose especially for bleeding brake in master cylinder
- Efficiently to Bleeding Work: It contains a variable thumb throttle which maintains average air flow rate 2 cfm and a desired brake fluid flow rate. And the fixing ring lock keeps extracting oil continuously, efficiently and quicker
- Quieter Work: Built-in Integrated silencer allows the brake fluid to flow quietly through the silicone hose and makes a messy job cleaner, quicker and quieter
- Convenient: Midget size of the N.W is less than 4 lb makes it easy and convenient to operate and carry even for women

## Questions & Answers

**Q: When attached to air hose the unit is continuously "sucking air" through the system without pressing the thumb throttle. Is unit defective?**
A: It could be, EB.  The valve, when depressed, admits air from the hose off of a compressor through an eductor to draw the process, air fluids or other, by the Venturi effect.  All of the air used for this will come through the vent diffuser opposite the hose connection.  When the valve is released, the air flow from the compressor supply should be shut off killing the Venturi effect and eliminating the air coming out of the vent diffuser.  Keep in mind that there is a trigger locking wire that can hold the trigger in the 'on position' so make sure that this is flipped towards the hose so that the trigger can release to its 'off' position.  When your's is 'sucking air' without pressing the thumb throttle, is air coming out of the vent diffuser opposite the hose hose connection on the valve assembly?  If no air is coming out from the vent diffuser with the trigger released, then you shouldn't be 'sucking air' and the unit would be in working order.

**Q: How do i contact the company?  there’s no website, phone, address or anything.  how do i get replacement parts?**
A: I need a replacement tube but I also haven't found a contact number, uggg

**Q: Should i hear an air hiss when i pump? i do and i lose vacuum pretty quickly and have to pump repeatedly.**
A: I think you lose vacuum when you hear the air his. It’s likely it’s coming from the adapter where you can connect an air pump to, but you don’t have to connect an air pump to it because it has a manual pump. So what I did was turn that stopcock perpendicular to shut that valve and then pump manually. If you meet some resistance stop pumping let the pump do the work, then resume pumping when the vacuum weakens. Too bad the package didn’t come with instructions. However this pump was really efficient and quick to use, not a drop of oil spilled.

**Q: I hear a hissing sound that seems to be air leaking back in. I closed the pneumatic valve but it still persists, Is there a fix?**
A: Did you try relief valve

### ⭐⭐⭐⭐ Updated Great Brake Bleeder
*by S***Y on June 27, 2025*

This product works great and makes one person brake bleeding a breeze. I did encounter an issue with the guick disconnect coupler where the bleed hose connects. The quick disconnect had a bad o-ring. The photo shows the damaged o-ring. I was able to remove the o-ring and finish the job. I reached out to Four Uncles and they quickly responded and are sending a replacement. Things happen sometimes and I'm very satisfied with Four Uncles support and offering a replacement. I highly recommend this product. The included fill bottle didn't mount to the master cylinder very well, bit it still came in handy for a "mess free" option of adding brake fluid without spilling. Updated 7/7/25 - The replacement was received with in 3 days from Four Uncles. Thier Customer Support is outstanding!
