ATE Brake fluid SL.6 DOT4

This brake fluid for hydraulic brake and clutch systems in motor vehicles is particularly well-suited for braking systems with electronically controlled hydraulic components due to its low viscosity in extreme cold, where rapid modulation of brake pressure at the braked wheel is required. This is especially important in systems designed to prevent oversteering or understeering of the vehicle, known as Electronic Stability Program (ESP). The viscosity at –40 °C is a maximum of 700 mm²/s, which is only about half as high as the corresponding values of many other commercially available DOT 4 fluids, thus meeting the requirements of ISO specification 4925 for low-temperature viscosity brake fluids (Class 6).

The brake fluid consists of polyethylene glycol ethers, polyethylene glycols, their boric acid esters, amines, additives, and stabilizers. The ATE DOT 4 brake fluid SL.6 meets and exceeds the requirements of brake fluid standards FMVSS No. 116 – DOT 4, SAE J1704, and ISO 4925, Class 6. The ATE brake fluid SL.6 can be mixed with other brake fluids that meet the specifications ISO 4925 Class 6, DOT 5.1, or DOT 4. However, optimal ESP functionality at very low temperatures is best ensured with fluids of the ISO 4925 specification, Class 6.
