Description
Genuine Carlyle · Part no. CBFTDOT4
The Carlyle CBFTDOT4 is a tester for checking how much water is in DOT 4 brake fluid. Its colour readings are simple: green shows no water in the fluid, yellow means less than 1%, and yellow/yellow means approximately 2% water content.
Good to know
- Why test brake fluid? It absorbs water over time, which lowers its boiling point; most car makers ask for new fluid every 2 years.
- What should I do if it shows yellow? Some water is present; plan a fluid change, and at yellow/yellow change it.
- Anything after the job? Brakes are safety critical: test them before driving.
Which one?
For a three-stage reading with a red warning, the Carlyle Pocket Brake Moisture Tester 3 Led Indicator (CBFTDOT4A) shows green below 1.5%, yellow from 1.5 to 3% and red above 3% water, and switches off automatically.
Key features
