Base: Made from mineral oils, which are natural oils refined and treated for use in hydraulic systems. Compatibility: Typically used in hydraulic disc brakes on bikes, where mineral oil is the preferred fluid due to its lower viscosity and better sealing properties. Viscosity: Typically lower than that of glycol-based fluids, which can provide smoother brake response and reduce seal wear. Non-corrosive: Mineral oil brake fluids are non-corrosive, meaning they are safer for paintwork and components in the event of a spill or leak, unlike DOT fluids, which can damage painted surfaces and rubber seals. Heat resistance: Mineral brake fluid typically has a lower boiling point than DOT fluids, so it is essential to ensure it is used in systems designed for it. Applications: Hydraulic bike brakes: Many modern bikes, especially those with hydraulic disc brakes, use mineral oil in their brake systems.M-WAVE may be a specific brand supplying this type of fluid for bike maintenance.
