Note: Before troubleshooting the brake system, make sure the tires are in good condition and properly inflated, that the front camber/toe is properly adjusted, and that the vehicle is loaded correctly. In case of any malfunctions in the anti-lock braking system, it is allowed to check the condition of all pipe and hose joints, in other cases, contact a Renault dealer for diagnostics.
