What is life expectancy of stock brake pad and rotors?
my last MB was about every 20k but I heard Japanese's brake pad and rotors last much longer.
TIA

It all depends on how hard you use them. I can trash a set of stock pads in 1/2 a day at the track. Haven't destroyed the rotors yet though and that's after 5 track days and 17,000 miles on the street.

let me put it this way then.
How do I check pad/rotors if they have plenty left??

I cant wait until pad making squeal noise because it take very long to get pad and rotors here.
I'm planning to pick up aftermarket one when I go to USA.

How many miles are on your car? It seems that most people with "average" driving are gettig 35,000 to 40,000 miles on the stock brake pads. Rotors shouldn't need to be changed unless they're damaged by brake pads getting too low.

There's no easy way to eyeball the pad thickness remaining so you'd have to pull the wheels and check the remaining thickness. Even better is to remove the calipers and check the thickness of the pads with a mm gauge.

The stock pads do have "wear sensors" that will start to squeal when they get to the point that they need replacing. If you're hearing a constant squeal from the brakes when they're not applied then it's past time to change pads and have the rotors checked.

I have about 15,000 but I did 5 Autox also I drive in heavy traffic in city and highspeed highway runs(arond 100mph). So I'm little concerned about its short life

I don't think you have anything to worry about after 15,000 miles.

wow... every 20k? ouch... remember also that S2k's are relatively on the lighter side... so less stopping power is needed usually.

Yeah on the outside, problem is the inside pads tend to wear a little faster in my experience and you can't see those without taking off a rim unless you're some sort of freak of nature

I have 60k miles and have only replaced the front pads and turned the front rotors once... no track duty though... if you don't drive like a maniac all the time they will last quite a while.
