Review on 🔧 EONLION 2L Vacuum Brake Bleeder Air Brake Bleeder Kit with Brake Fluid Extractor and Refilling Bottle - Includes 2L Extractor & 1L Refill Container, Plus Silicon Hoses by Juan Castillo

The EONLION 2L brake vacuum pump is a complete kit that includes everything you need to bleed your car's brake lines. It includes a 2 liter plastic brake fluid suction bottle, a brake fluid refill bottle and two plastic hoses; one to attach to the brake bleeder valve and the other to bleed the brake fluid from the master cylinder. The sampling bottle is connected to the vehicle's brake bleeder valves with the appropriate hose attached. It uses the vacuum created by a connected air compressor hose to draw brake fluid from the brake lines. left rear wheel, then the passenger wheel, and finally the front wheel on the driver's side. The idea is to start with the wheel farthest from the master cylinder brake fluid reservoir, which is located on the firewall under the hood in the engine compartment. Then continue with each wheel approaching in turn while you begin to get new fluid from the brake drain hose from the kit. It sits upside down in the brake fluid reservoir and gravimetrically adds fresh brake fluid to the master cylinder reservoir as the fluid in the reservoir drops when the brake lines are drained. It's a simple system, but it works great. As said, using the kit is easy. Unfortunately, reliance on compressed air is its Achilles' heel. My pancake compressor couldn't handle the volume of air the bottle needs to extract the brake fluid. I was able to completely drain the old brake fluid by jumping in the car and depressing the brake pedal to speed up the evacuation of fluid from the brake lines, thereby reducing the amount of compressed air needed to prime the extraction bottle. Towards the end of my brake fluid change project, my air compressor was making a loud thumping noise as it tried to fill the air demand. It felt hot after I finished the project. I thought I damaged it, but once it cooled it seemed to work fine. I watched a YouTube video on how to change brake fluid using a kit similar to EONLION's. Unfortunately I checked it out after I had already done the work. One suggestion is to loosen the wheel fluid drain valves just enough to allow fluid to flow out of them. According to the video, over-loosening the brake valves can allow air to enter the drain hose between the valve threads, making it difficult for the compressor to pull them out. Maybe I made that mistake. However, despite this flaw, I realize that those with large air compressor engines and compressor tanks have a distinct advantage. If I'm still having trouble the next time I change brake fluid, I turn off the compressor and use the brake pedal method to force the fluid from the brake lines into the reservoir. This should do my job of changing brake fluid with ease.
