Suzuki Repair: brakes, suzuki baleno, brakes squeal

Question
i have a suzuki baleno year 97
sometimes i ear noise from the front wheel when i use the brakes
its does not happen always
i check the pads but its seems to be ok  

Answer
Sometimes, that's a wear indicator, and much of the rest of the time, the brakes squeal, frequently from light application.  You might try stopping quite hard a couple of times, and then see if the squeal is still there.  Even though it's counter-intuitive, occasional heavy use is ok, and even desirable.
