Review on Calibrated ITEQ Brake Fluid Tester Pen With 5 LED Indicators For Accurate Testing Of DOT3 And DOT4 Brake Fluids by James Womble

Revainrating 4 out of 5

Good enough for initial indications

This tool seems adequate to learn the ballpark status of the brake fluid's H2O content. It is not precise. For a more accurate measure, use a multimeter (instructions abound on the 'Tube.) Still, if this tool indicates excessive H2O content, that is probably enough to warrant flushing (not just bleeding) the vehicle's brake system.

Pros
  • Brake System
Cons
  • The pen may not be reliable for use on high-performance vehicles
