Product Information
Dobang DOT4 / HZY 4 synthetic brake fluid for the motor vehicle
Product Features:
Maintain braking performance longer
With a higher boiling point, and maintain the use of a stronger boiling point of this characteristic, can greatly reduce the formation of high temperature gas resistance in the work, to ensure that its braking performance is better and longer.
Protect the metal surface more comprehensively
The special buffer formula keeps the PH value within the alkaline range, and the advanced additive technology provides comprehensive corrosion protection for metal surfaces such as aluminum, brass, copper, zinc and tin
Can reduce the leakage and pressure loss
The correct seal expansion rate can effectively minimize the leakage due to the seal contraction and the wear of the active parts due to the excessive seal expansion.
Improve the service performance and its service life
Outstanding thermal stability and oxidative stability, effectively prevent the deterioration of brake fluid and the generation of harmful deposits, to ensure that the overall life of brake fluid and key performance remain reliable
It has cleaning function
Excellent cleaning function can effectively clean the residual water and mud impurities in the brake pipeline out of the brake system, prolong the service life of the brake system, so that the brake performance recovery as before.
Applied Range:
It is widely used in various traditional hydraulic braking and clutch systems, especially in harsh working conditions or when DOT 4 brake fluid is recommended. With the lower performance standards of braking
This product provides greater safety protection against “air resistance” than brake systems (disc or drum brakes) requiring hydraulic fluid with DOT 4 or SAEJ1704 specifications.
Meet or exceed the following industry specifications GB12981-2012
