Brakes, Wheels & Tyres

Opirus´ braking system is powerful, responsive and highly effective. Large diameter ventilated discs (303 mm front) and solid discs (284 mm rear) resist heat build-up and fade, and deliver sure and stable braking performance. Standard equipment includes an advanced Kia-developed ABS system that is lighter and more responsive than previous systems and comes with four channels and four sensors. The ABS system also incorporates an emergency brake assist system (BAS), electronic brake force distributor (EBD) and is linked to the traction control system (TCS).

ABS allows the driver to apply maximum brake force to all four wheels without locking them and to retain steering control even on wet and uneven surfaces. When activated by heavy braking on a slippery surface, it applies and releases the brakes at a rate of 30 times per second, preventing wheel lock up and allowing the driver to retain steering control. The Emergency Brake Assist System (BAS) senses when a driver is braking in an emergency and immediately applies maximum available power boost. BAS overcomes the human tendency not to brake hard enough, soon enough.

The integrated EBD system acts as a brake booster, helping to distribute braking force evenly among all four wheels by regulating the number of pumps required to prevent skidding. The system adapts to different wheel grip conditions, and distributes braking force front and back according to the vehicle weight, which differs according to the number of passengers and the cargo load. The net result is shorter, safer braking distances. On straight roads, the EBD-ABS system automatically adjusts the braking effect to ensure the car tracks along a true course, under braking. It also allows simultaneous emergency braking and emergency steering to avoid obstacles - all without wheel lock-up.

The parking brake is engaged by a foot-pedal and immobilises the two rear wheels of the car. The brake is released by a pull-handle located on the lower left side of the dashboard, adjacent to the steering wheel.
