Find out more about our brake fluid tester:

The brake fluid tester is a useful accessory for all vehicle owners who want to check the quality of their brake fluid. It lets you quickly check the level of moisture in your braking system. This easy-to-use test pen displays the results in just a few moments, thanks to its green, yellow and red LEDs, which indicate the quality of the brake fluid. If the light is red, it's time to change the brake fluid.

This tester is compatible with various brake fluids, including DOT3, DOT4 and DOT5. Its built-in moisture gauge allows you to carry out a thorough check of the water content in brake fluid. It is considered one of the best products on the market for determining the quality of brake fluid, which is essential for the smooth operation of your vehicle's braking system.

It's easy to use: simply dip the electrodes into the brake fluid. The LED then gives a precise indication of the percentage of water present in the fluid. It's important to remember that brake fluid is hygroscopic and can degrade over time. So, to ensure optimum braking performance, it is essential to check its condition frequently.

The brake fluid tester is powered by AAA batteries and features a cap that protects the electrodes from corrosive elements. Designed to be tough and durable, it's perfect for mechanics and vehicle owners who want to monitor the condition of their braking system. It's important to check the quality of brake fluid frequently to keep your car running smoothly. In addition, the manufacturer's recommendations must be followed to replace the brake fluid on time and maintain stability at temperatures of up to 140°C to 180°C, the boiling point of brake fluid.
