### ⭐⭐⭐⭐⭐ Works well

### ⭐⭐⭐⭐⭐ Good solution.

### ⭐⭐⭐⭐⭐ Save a life, check your brake fluid.
*by R***N on July 28, 2025*

I was highly skeptical that I needed one of these in my life. Then I opened up my brake fluid which was supposedly being done at the dealership for the last 3 years and it was green. No not black, green. Yes that's right, the brake fluid was green. I'm talking green like Green Eggs and Ham , yes Sam I am. I threw the test pen into the master cylinder and it said 4%, which I guess is red for dead. This is the easiest thing to use in the world, you click the button unscrew the master cylinder throw the tester into the brake fluid and look for the light. You have a 5 position light that indicates what percent the amount of water in the brake fluid is. Green for go, yellow for warning and red for dead. Looking at the brake fluid you could clearly tell it was very bad so obviously the tester itself is accurate. The build quality seem sufficient for what it is, it does not say it is waterproof so make sure to only immerse the testing probes. I recommend not storing a battery in the pen if you're going to not check anything long term. Oh yeah you need 1 AAA battery that should last forever. Now I'm spending $200 on Amazon for an automatic brake flushing machine so I never have to pay the dealership again. You should too, It'll help the economy.
