This AST603 brake oil changer is really efficient. One‑button pulse operation makes brake fluid replacement easy, and it can even work on two sub‑pumps at the same time. The intelligent liquid level monitoring avoids air entering the system, and the corrosion‑resistant hoses are solid. It fits most car models and comes with clear gauges and stable connectors. Very professional and convenient for auto repair.

Received it within 4 days. The machine itself is fantastic, heavy stainless steel body, feels very professional. The adjustable pulsating pressure gets you a rock-hard pedal every time. Knocked off 1 star because the English manual is poorly translated and missing clear steps on how to properly depressurize the unit before disconnecting from the master cylinder. You’ll figure it out quickly (just crack the pressure release valve), but the manual is weak.

Works well, has long reaching power cord (around 6ft) and brake fluid hose. Portable, light at around 10 ibs. Only drawback is that most over the counter brake fluid containers are smaller than the suction hose off of the machine. That, and only three adapaters for brake fluid reservoir. Granted, they are the 3 most popular modern styles. If you need another style though, you’ll most likely have to buy another adapter kit and modify the adapters to work with this machine.

Excellent product, works well and they honor the warranty. It’s not the only device from this brand that I own, and they’ve all been excellent.

It does the job perfectly; you can work with it alone. The equipment is very practical and safe to use. 100% recommended.

This is a great brake fluid change tool. I can actually buy an extra fluid can and change both wheels at the same time. I no longer need two people to work together, and I can easily change it by myself. Most importantly, there are no bubbles, which is great.

The AST603 is well-designed and easy to use. Its pulse-activated one-touch oil change function allows for efficient and precise oil changes without introducing air. The intelligent fluid level monitoring feature is excellent—it automatically stops when the fluid is depleted, effectively protecting the brake system. It also comes with a durable, corrosion-resistant hose. Overall, it’s a reliable and practical tool that I highly recommend.

Fantastic seller! The item was shipped lightning-fast and arrived exactly as described. Perfectly packaged to ensure no damage during transit. Communication was prompt and friendly. Couldn’t ask for a better experience. Highly recommend!

This product helps me quickly change my brake fluid. It’s quick and easy, and even one person can do it easily. I highly recommend it to anyone who wants to try changing their own brake fluid.

I’ve tried many different brake fluid exchangers, and the AUTOOL is by far one of the best. It works perfectly on my cars, even with electronic parking brakes. The bleeding process is smooth with no air bubbles, and it’s easy enough for one person to change the brake fluid efficiently. On top of that, the seller offers great prices and very fast shipping—I’ll definitely keep purchasing from them.
