Phoenix Systems (3001-B) Brake Fluid Test Strips, 100 Test Strips Per Tube, BrakeStrip, FASCAR, Copper,White

We use these all the time. Great value for what you get

Works just like they said. It's important to note that you should test for BOTH moisture AND corrosion in your brake fluid. These test for corrosion and you can get something else from amazon to quickly and electronically test for moisture. Glad I got them. Of our five vehicles, it showed that one of them needs to have its lines flushed. The strips didn't show severe corrosion, but compared to the other four vehicles it was not so good so I am treating this as an "early warning" system.

Most shops "look" at brake fluid and determine from visual inspection if the fluid needs to be replaced. This subject analysis really misses the mark and causes the image of the automotive repair industry to be tarnished. I have seen absolutely black brake fluid pass the FASCAR test as well as the moisture test. If you are in the business of automotive repair, invest the money on these strips as well as a moisture content testing device. When used together, they can be used to show the customer without a doubt if the brake fluid needs to be replaced and why.

Used daily. Easy to use. Great bang for your buck. Functions as advertised.

These are the best test strips

An interesting and novel idea to test for contaminated brake fluid. It worked just fine on the 3 cars I tried it on. 2 of them need the fluid flushed after finding the fluid bad.

these strips do not work at all, tried on different types of brake fluid brands and never worked, garbage

I am an auto repair shop . this works . I have used these strips for 6 years .
