Brake fluid tester

This professional brake fluid tester tests the percentage of water in the brake fluid.

Simple and fast test method for an important safety check.
Works very accurately and gives a reliable test result.
Brake fluid must contain less than 2% water.
Color-coded LEDs indicate the water percentage.
Small in size due to the compact housing.

LED color coding:

• Green: very good, no water
• Green + yellow: in good condition, less than 1% water
• Green + yellow + yellow: replacement recommended, about 2% water
• Green + yellow + yellow + red: replacement recommended, about 3% water
• Green + yellow + yellow + red + red: replace, at least 4% water

Why replace brake fluid:

• Brake fluid has the property of attracting water
• The brake fluid can become hot, which can cause the water present to boil
• That means air bubbles and as a result: loss of braking power!
• Water in brake fluid also causes corrosion (rust) in the brake system
• Corrosion has adverse effects such as jammed brake cylinders and leakage
