Listen to what other users say about this Brake Fluid Tester?

  1. I work in a large dealership. The first thing we do when we receive a car or truck is to perform a detailed inspection of the vehicle.

I bought this tool to do more than a quick look at brake fluid level and to see if the fluid was discolored over time.

What we have found out to be true is vehicles with 30,000 miles, the tester shows 1% water content. 45,000 miles or so, the water content is 2%. 50,000 to 60,000 miles and the water content is 3% or higher. It’s good to us!

  1. I normally flush the braking systems on my family’s cars every three years. I find newly flushed cars have the minimum lights lit and the cars nearing three years have red lights lit. It’s a good indicator of your fluids condition.
  2. I can confirm this tester works as I tried it on three cars with known brake fluid age. And the old one showed 5%, the middle one showed 1% and the new one showed 0%.
