Description
High quality brake fluid based on complex mixture of polyalkylene glycol ethers and esters of boron with the addition of highly effective inhibitors and additives. Due to the excellent stability and resistance to high temperatures DENTO BRAKE FLUID DOT-4 prevents the formation of residues and deposits on surfaces, even in severe operating conditions with frequent and heavy braking. Low volatility prevents vapor locks, thus it ensures excellent braking performance and additional reliability margin. DENTO BRAKE FLUID DOT-4 provides long-term protection against corrosion of all materials used in brake systems: metals, plastics and elastomers. DENTO BRAKE FLUID DOT-4 is non-aggressive to rubber and polymer seals used in brake systems. The product exceeds many common quality standards for brake fluids, which are recommended by automotive manufacturers.
Application
DENTO BRAKE FLUID DOT-4 is recommended for a variety of automotive hydraulic brake systems (including those equipped with ABS electronic systems), which require DOT 4, SAE J1704 and ISO 4925 Class 4 fluids.
DENTO BRAKE FLUID DOT-4 is suitable for use in auxiliary hydraulic drives of cars and various commercial vehicles, including traction drives and hydraulic rams. ATTENTION: In absence of OEM specific requirements, it is recommended to change brake fluid once every 2 years. Do not mix with brake fluids based on mineral oil (LHM) and silicon based fluids (DOT-5). Brake fluid absorbs moisture from air. Moisture in fluid significantly reduces brake fluid boiling point with a possible risk of vapor lock. Before using this product make sure, it is consistent with OEM’s recommendations for the equipment operating conditions and customer’s maintenance practices.
Manufacturer benefits (EN)
High boiling point (above 250 °C) and excellent thermal and oxidation stability prevent the formation of vapor locks in vehicles, operating with heavy braking.
Inhibitors provide long lasting protection against oxidation of various metal parts including those made of aluminum, brass, copper, zinc and iron.
DOT-4 type brake fluids is suitable for change, top up or maintenance servicing of brake systems with obsolete recommendations like DOT 3, SAE J1703 and ISO 4925 Class 3.
