    Expert Installation & Field Note

    Based on our shop experience specializing in heavy-duty brakes since 1985, remote reservoirs are often the first point of contamination. When installing this new unit, thoroughly flush the supply lines leading to the master cylinder. Ensure the low-fluid sensor connector is clean and free of corrosion to prevent false dashboard warnings. Always use fresh DOT 3 or DOT 4 fluid as specified by your vehicle manufacturer.
