Brake Fluid Tester

Easily test the quality of your brake fluid.
Measures how much moisture/water the liquid contains.  
Brake fluid that has retained a lot of moisture can be a traffic hazard, as this lowers the boiling point of the brake fluid and can cause the brakes to stop working completely.

Measure your brake fluid at each service to make sure everything is in order. Lower the pads into the fluid and press the top button. You will immediately get an indication of the condition of the fluid.  

Works on DOT 3, DOT 4, DOT 5 and DOT 5.1.
