You need to drive it and break the pads in.
Hi Rem,
This problem occurred 3 month ago and still. My friend drove the car for a while, brake work okay but just soft feeling. It was firm before.
Could it be the Master Cylinder bore worn out?
thanks

Yes its possible. First I would try and bleed the h3ll out of it to make sure thats not the problem. Discs on the rear? If drums, they could very well need to be adjusted.
If the system had a small amount of air in it you would be able to pump the pedal which would compress the air and get a hard pedal. The same would happen if rear drum brakes were out of adjustment. If you can't pump the pedal and make it feel more firm I don't know what to tell you. If it has rear disc check and see if there is any space at all between the pad and rotor.

Make sure that the pads are properly seated (i.e. that they aren't "off the track"). This can cause your brake fluid reservoir to overflow and the brakes to feel really soft after a pad change. Don't ask me how I know...

Its rear disc, I will check those pad later.
Btw, what are symptoms of Master Cylinder worn out? Pedal go to floor? bubble in reservoir when applying brake etc..???

If you clamp the rubber brake hoses, you will quickly determine if the problem is m/c , or brake assemblies. The pedal should be rock hard.
Whats an idea!! I will try that but how would you clamp/lock the rubber hoses without damage it??
