Can You Use Car Brake Fluid in a Mountain Bike? Exploring the Pros and Cons
No, you shouldn’t use car brake fluid in a mountain bike. Car brake fluid is designed for hydraulic systems that operate at much higher temperatures and pressures than those found in mountain bikes. In addition, car brake fluid can damage the seals and components of a mountain bike’s brake system. It’s important to use the recommended hydraulic brake fluid for your mountain bike, as specified by the manufacturer.
