Hi

thanks for your reply.
I looked also online to find out and it says it is brake master cylinder.
I found some for 75 dollars only and new.

Well. They have took off the tires and checked it with something. I believe now that they checked the brake fluids. They told me then that they cannot change the brake fluid as the part mentioned does not provide the rear with the brake fluid. They told me that is maybe why I have problems to brake when they get hot after driving for a few hours such in serpentine, mountains, going downwards. I had to push brakes 3 times then to get the brakes work.

Well, after everything I sit down in the car, started the engine and used the brakes. The thing was that they did not apply at all. I could push the brake panel down. Also the brake light went off (in red) and that was the point when I said that I am not driving the car back home.
They started to take off a little part from the brake fluid box and pushed the box around and took the switch out and in etc. Then they said i can try to drive it home. No way!! That was too dangerous as the brakes could stopp at any time.

Due to the cylinder which did not provide the rear with fluid, they told me to get a new part and replace it. That would be better. But in my country they dont have those parts as they built the same car differently.
Mine is american...

To answer your question. Yes, the brake pedal went all down to the floor. brakes did not apply. And to me it is not safe to drive it like that also after they played around with the fluid box and telling me that i should replace soon and be careful as it could stop working just like that.

it is hard to get the car proper down in a country where you cannot just get parts and if, they are more than 2 or 3 times expensive than in america. Cant pay that all the time...
