The brake systems of N2 category vehicles might be insufficient in challenging road and use conditions, especially depending on geographical conditions. This situation might cause accidents with loss of life and property. Pneumatic brake system, which we have developed to prevent such risks and received a patent for; is successfully applied to N2 category vehicles. This system can be made as two systems, either pneumatic system or semi-pneumatic system, depending on customer request and vehicle model. Our original brake systems are installed on vehicles in accordance with type approval certificates issued by TSE. Vehicles with a modified brake system go through all the technical tests required by TSE.
