Keep Your Brakes Safe with Easy, Accurate Fluid Testing

Ensure your vehicle’s braking system is always performing at its best with this Universal Brake Fluid Tester Pen. Designed for quick and reliable checks, this handy tool measures the moisture content in your brake fluid—an essential factor that affects braking safety. With a simple LED display, you can instantly know if your brake fluid is fresh or needs immediate replacement, helping you avoid costly repairs and maintain smooth, responsive brakes.

Key Features That Make Testing Simple and Effective

This brake fluid tester works by detecting changes in the fluid’s conductivity caused by moisture buildup. Moisture in brake fluid lowers its boiling point, reducing braking efficiency and safety. The tester’s LED lights show you the exact water percentage in your brake fluid, so you can act before problems arise.
  • Clear LED Indicators: Five LEDs light up in green, yellow, or red, showing water content levels from 0% to 4% or more.
  • No Cables, No Hassle: Compact, pen-style design for quick, cordless testing anytime, anywhere.
  • Easy to Use: Just dip the probe into the fluid and read the LED lights for instant results.
  • Portable and Lightweight: Made with durable ABS material and powered by a single AAA battery (not included).

Why Choose This Brake Fluid Tester?

Regular brake fluid checks are critical for vehicle safety, but many overlook this simple step. This tester gives you a professional-grade diagnostic tool at a fraction of the cost. It's perfect for car owners, mechanics, and anyone who wants to ensure their brakes function reliably under all conditions. Use this tester during routine maintenance or whenever you notice changes in braking performance. It’s especially useful before long trips or harsh weather conditions, where brake reliability is a must.

Benefits at a Glance

  • Prevents Brake Failure: Detect moisture early to maintain brake fluid quality and avoid dangerous brake fade.
  • Saves Time and Money: Avoid unnecessary fluid replacements by testing first, ensuring you replace only when needed.
  • User-Friendly Design: Quick, no-mess testing with easy-to-understand LED results.
  • Compact and Portable: Carry it in your glove box or toolbox for on-the-go peace of mind.
