Five LEDs give you the reading after one second. It's for drivers who look after their own car or van, and for anyone who wants to check the brake fluid before a long drive.\u003c\/p\u003e\u003cp\u003eBrake fluid draws in moisture over time through the porous brake pipes, so it can start forming vapour bubbles below the boiling point printed on the label (\u003ca href=\"https:\/\/www.bremboparts.com\/europe\/en\/support\/insights\/brake-fluid-why-it-s-vital-for-your-vehicle-s-braking-system-207814\"\u003esource\u003c\/a\u003e).
