I have a daihatsu storia 1998. When i apply the brakes and Tak-Tak-Tak sound is heard and you feel the movement of the brakes applying in the pedal.

What can be the cause of it?

Can the ABS be faulty or the sensors are faulty?

Also where can i get a manual for the car or the software used on diagnosis machine to diagnose the vehicle. i do not have the software for the 1998 model.

thanks for the help.
