My car "jerk" when I release brake pad after a complete stop, I felt it half second after the moment I release brake pad. and also when I come to a complete stop, at last second the car just stops suddenly, like it's got glued. these happened first 5 minutes of everyday drive, after that it all backs to normal, anyone know what's going on with it?

 

It's been like this for a month now, nothing special that I have done to my car month ago

 

You may have pockets of air in your brake system. I know you said: "nothing special that I have done to my car month ago"; but did you replace your pads recently, and have you checked under the car for any suspension problems?

 

No I haven't, it only occurs the first 5 or 10 minutes driving tho, is it because brake system still cold?

 

Only if you have performance pads, but you would notice the squeeks, also, once the brakes are applied before it has completely warmed up. Try posting and reading this thread: Brake FAQ
