Product Overview
YW-791 Oil Moisture Brake Fluid Detector Auto DOT3 DOT4 DOT5.1 Brake Fluid Tester
YW-791 is a testing device that determines whether the brake fluid needs to be replaced by detecting the water content in the brake fluid. It can be used to detect brake fluid DOT3, DOT4 and DOT5.1. Suitable for most vehicles. Multiple Oil type detection with high sensitivity sensor.
Why We Need It?
The brake pressure is transmitted by the brake fluid. Once there is too much water in the brake fluid, pressure transmission will no longer work. Therefore, for driving safety, we need to regularly check the proportion of water in the brake fluid to ensure that you are driving in a safe state.
