Your description of your problem is extremely unclear. I wish that I could help you, but it is very difficult for me to understand what you are trying to say. My suggestion to you is, if your brakes do not work properly on a car only one year old, you should take it to your dealership for warranty repair.

It sounds like your brake fluid could be diluted with water that is expanding as it is heated creating steam except that in most cases where that occurs the brakes lock up when there is no pressure on the pedal and the car will slow to a stop while under power.

But, what do you suppose is the source of the heat that is boiling the water in the brake fluid? The OP doesn't say that the brakes don't work (slow or stop the car), just that the pedal "be harden like stone after 20 minutes". After my reply to his post, he left a similarly mysterious visitor message on my profile page. I am not trying to insult his English- the problem may be mine. I just don't understand all of the details of his problem.

The owner of a 1 year old car should not be expected to diagnose and fix brake problems on a new car.

It is odd that a new car would have this problem..... I have had ti happen on cars with hydraulic clutches and brakes. They will build up so much pressure that the clutch will not engage or the brakes engage..... The heat comes from the wheel cylinder or calipers on brakes or the slave cylinder on clutches...... Somehow water has gotten into his brake cylinder or if the brakes are working but require more effort it could be caused by a vacuum leak or bad brake booster ..... I had to change out all of the fluid in my wife's 95 GMC truck due to water in the hydraulic lines..

I think that for any of us to diagnose the problem on a new Fit, we need more info. But this should not be necessary for the owner of a relatively new Fit.
