Hello all !
This week end i got a weird problem with my car.
I was driving for maybe half an hour and it was some kind of a hot day. For some unknow reason , the brake pedal went almost to the floor... it was working flawless just 5 minutes before ! So i just pump the brake and i was able to stop the car.

Anyway after a fiew stop i was at home so i park the car. Maybe 1 hour later i pick up the car again... 20-25 minutes of highway and suddenly , again , brake pedal almost to the floor ! ... it still brake but i have to pump brake pedal for having some pressure on it.

4 hours later i pick up the car again and everything is fine , no problem at all !
This morning , went to work ( maybe 20 miles from home ) and no problem... comming back this afternoon , no problem !

I found a procedure on honda-tech to check the brake ( master cylinder , booster problem and etc ) and everything seem fine. The pedal is not stinking even if i hold big pressure on it when the car is off.

I really dont know what happen ! No apparent leak , oil level is good ...

The last thing i do on the car is put back oem suspension ... i dont know if it can help you to diagnose my trouble.

So now , everytime i have to do a stop , my heart is racing cause i never know if my brake pedal will work fine or not , that really **** me...+ my GF is pregnant so i really want to found the problem , i dont want to be involve in any accident.

If you have any idea , feel free to help please
Thanks all !
