4AN Brake Hose, Reservoir to Front Master

Braided stainless steel brake line connecting the brake fluid reservoir to the front master cylinder. This line uses 4AN (3/16" nominal bore) fittings and allows gravity-fed brake fluid to flow from the reservoir into the master cylinder as fluid is displaced during brake pedal operation.

The braided stainless construction prevents line expansion under pressure and resists abrasion from vibration or contact with other components. The 4AN size is smaller than the 3AN lines used for the pressurized brake circuit, as this is a low-pressure feed line rather than a high-pressure brake line.

This is an OEM replacement part that comes standard with the Rush SR brake system. Pre-made to the correct length with fittings installed.
