Not too sure about the "expectation" theory, because this is my first ride, so rightfully, I shouldn't have anything to compare with.
I just felt that it doesn't feel as "jiak" as in the first couple of months. Last week, I jam braked couple of times because somehow felt that the pressure I used to apply on the brakes to slow down the car suddenly had to be increased.
I called my SA and he said may be due to wet weather recently, so brake pads may be wet or something.
