Review on FOUR UNCLES 2L Vacuum Brake Bleeder Kit - Air 🔧 Brake Bleeder with 2L Brake Fluid Extractor and 1L Refilling Bottle by Napoleon Robbie

The kit for bleeding the brake line includes two hoses. One of these you would use to bleed the brake fluid directly from the master cylinder. And other hoes have a connector that connects to the exhaust valve on the caliper. This is the tubing I used and here is how I used this kit. 1. Filled the reservoir with Dot 4 brake fluid my car needs. Pull out the filter at the top of the master cylinder and set it aside. Turn the refill bottle upside down and insert the end into the top of the master cylinder. They are tightened with a knurled screw. This ensures that the brake fluid drained from the cylinders is replaced with new brake fluid. This ensures that no air gets into the brake lines.2. Always start with the rear wheel farthest from the master cylinder at the opposite corner. My master cylinder is right in front of the steering wheel so I connect it to the caliper on the rear passenger side.3. Connect the vacuum block to the air compressor quick connector. And connected the caliper hose, which also has a quick connector. Then connect the other end of the drain hose to the caliper drain valve.4. Then he opened the valve, pressed it and everything was on vacuum. I watched the liquid drain out and waited until there was about an inch to one inch of liquid at the bottom of the vacuum reservoir. Then I close the valve, remove the tube from the valve and put the tire back on.5. Then I did the rear caliper on the driver's side the same way and drained about another inch of fluid. Then I did both front calipers. They have less fluid in the lines because they are closer to the engine. I did between an inch and an inch and a half from both front calipers combined. On the 4th caliper I could see the cleaning fluid getting into the vacuum reservoir. I closed the valve and both front wheels started spinning again.7. Then I turned the car on and bled the brakes to build pressure. I put it in reverse, backed up a bit, and braked a few times. My brakes work great and have new, clean brake fluid.8. I have put dirty brake fluid into empty point 4 brake fluid reservoirs and will take them to my local hazardous materials collection point. The brake bleeder kit was very easy to use and I'm very glad I found it.
