PKDM Baleno, no model was introduced with ABS...
however 1.6 gti has better brakes having ventilated disks in fronts as compared to solid disk for all other versions...and it did a pretty good job...trick is dont alter the suspension and ride height in any way...also keep the stock wheels.
however you can install if u get ur hands on uncut wiring for ABS actuator...uncut brake lines....ABS sensors with HUBS from a donar car...else its highly non recommended to alter factory brakes of ur car....
