Shimano Hydraulic Mineral Oil Brake Fluid is the only oil formulated specifically for Shimano hydraulic disc brakes. It is designed to deliver optimal performance, ensuring smooth braking response across all terrains and riding conditions. Stable Under Pressure: With a high boiling point of 536°F, this mineral oil maintains consistent braking performance even under extreme heat. Whether you’re descending long mountain passes or riding in hot climates, the fluid resists fade and preserves braking power. Protects Your System: Unlike generic brake fluids, Shimano’s mineral oil is hydrophobic, meaning it doesn’t absorb moisture. This prevents internal corrosion, reduces the risk of vapor lock and extends the lifespan of your entire braking system. Eco-Friendly and Reliable: Formulated to be environmentally safe, Shimano Mineral Oil is both non-toxic and biodegradable. It’s the trusted choice for riders who want lasting performance without compromising their bike’s integrity or the environment. This mineral oil is gentle on your brake seals, hoses and internal components. Its non-corrosive formula minimizes wear and ensures your braking system remains responsive and reliable with less frequent servicing.
