Magsisisi ka lang sa Rapide. Bakit mo naman naisip dalhin dun? Sasabihin lang nila palitan 'lahat'.

The ABS of a typical braking system looks like a box with lots of hoses/hardlines sprouting from it. This is the part that controls brake pressure to each wheel to prevent lock up. AFAIK, that is the most expensive part.

Other parts that can cause a spongy pedal would be the brake master cylinder which all cars have (ABS or non-ABS).

There are other ABS components like wheel sensors, ECU, wiring, etc. that play no part in determining pedal feel.
