Otherwise I can install ABS in it
Maruti Esteem VXi did not have an option of ABS and installing it is practically not possible as it is planned in the early stage of production and later on connecting it to the brakes would not be possible. You can just get new and better brake pads from a reputed brand and even change your tyres and switch to those which offer the best road grip but installing ABS would not be possible for the car. The ABS can be found as early as in the Swift VDi and that too comes factory fitted, making its cost low and working effective. From 2017, the bike and car makers would have to install ABS as it would be mandatory in India.
I own a Vxi 2004 model and it doesnt have ABS which is the worst thing with the car. The braking is very bad if you are considering high speed drives. For your model check on ignition if the ((ABS)) logo is blinking, if it does you must have got it. Otherwise do a sudden brake on the road and see if your car stops with a DaT..DaT.DaT.sound, if so you have ABS. make sure you are on an empty road.. 😀
