The Ford Brake Fluid Test is a 60-second test that identifies serious brake system problems before they occur. Each test strip uses strict Motorist Assurance Program (MAP) guidelines and DOT standards for brake fluid testing. Each bottle contains 100 test strips. The Ford Brake Fluid Test Strip is the only proven scientific method to reveal when brake fluid needs to be changed or whether it can wait. Shops use the strips to deliver the safest vehicle possible to their customer. On average 1 out of every 2 cars on the road today are testing positive to needing their brake fluid changed.
