Why brakes are less responsive then before?

[quntinhen]

i have been using these brakes for 4 months now and i drive to and from Abu Dhabi but since yesterday i am feeling that brakes are not as accurately responsive then they were in past.

What could have caused this to happen?

life of brakes really depends on its usage. the more you use the more frequently they have to be changed.

this is how it works in my opinion the brakes need changing before you face further problems.
