Keeping track of your brake fluid can be crucial. FluidCheck is a handy tool that can provide a quick, visual indication of fluid condition - right on the spot in your garage or driveway.

Quick Visual Check - Without Complicated Steps
With just the push of a button, you can activate FluidCheck and dip the test probes directly into the brake fluid reservoir. Within a few seconds, a colored light pattern appears that can provide guidance on whether the moisture content is low, moderate or high

When to Change the Brake Fluid? FluidCheck Can Help You Be More Prepared
Brake fluid absorbing moisture is not unusual. Over time, it can affect the fluid's properties - but it's hard to see with the naked eye. the FluidCheck is designed to give you a quick indication of the situation, so you can make a decision before it becomes a problem.
