During installation, brake lines must not be twisted or excessively bent, and the braking system must be properly bled after installation. Brembo also lists indicative torque values of 17–20 Nm for the brake fluid union and 12–16 Nm for the bleed plug, while caliper fixing bolts should follow the motorcycle manufacturer’s specified torque.
