Collection: Brake Fluids for Harley-Davidson, Indian, and Metric Custom Motorcycles

A thin layer of fluid fills the space between the movement of the brake lever and the actual clamping of the caliper – and this fluid determines how accurately and reliably your braking system responds. Brake fluid transmits hydraulic pressure from the master cylinder to the caliper, essentially "translating" your hand or foot movement into actual braking force. Over time, however, brake fluid absorbs moisture from the air, which lowers its boiling point – and this can lead to a "spongy," uncertain brake feel during intense braking, because the moisture in the fluid boils and forms gas bubbles in the system. In our range, you will find brake fluids for Harley-Davidson, Indian, and metric custom motorcycles, in DOT 3, DOT 4, and DOT 5 certified versions, all in accordance with factory specifications. Both synthetic and silicone-based fluids are available, depending on the type of braking system – it is important to always use the type prescribed for your motorcycle, because DOT 5 (silicone-based) cannot be mixed with DOT 3/4 (glycol-based) fluids. Quality brake fluid ensures a stable boiling point, reliable pressure transmission, and long-term protection for the internal components of the braking system, such as rubber seals. Whether your goal is a regular brake fluid change or a complete brake system bleed, you will find the brake fluid that precisely meets your motorcycle's specifications.
