5101 Brake Fluid Tester – 5-LED Water Content Meter for DOT Fluids
5101 Brake Fluid Tester – Water Content LED Meter
The Motive Products 5101 Brake Fluid Tester gives technicians and DIYers an instant, accurate read on brake fluid condition. Insert the probe, press the button, and a 5-LED bar graph displays water content from 0% to 4%+ — no test strips, no lab equipment, no guesswork.
Key Features
- 5-LED Bar Graph – clear indication at 0%, 1%, 2%, 3%, and 4%+ water content levels.
- Built-In Self-Test – verify sensor and circuit integrity before every measurement.
- Wide Fluid Compatibility – works with DOT 3, DOT 4, and DOT 5.1 glycol-based fluids.
- Compact & Portable – pocket-sized for on-vehicle reservoir dip or fluid sample testing.
- Long-Life AAA Batteries – hundreds of tests per set; low-power electronics.
Service Guidelines
- Street use: Flush when tester reads 3% or at 2-year intervals, whichever comes first
- Track / HPDE use: Flush before every event; water-contaminated fluid vaporizes under repeated hard braking
- Fleet / commercial: Log readings at each service interval to trend fluid degradation
Pair with any Motive Power Bleeder for a complete test-and-flush workflow in one service visit.
