Brakes failing

Maybe it's time to take your car to a qualified mechanic and have them repaired. Stop being a fool and stop trying to do it your self unless you are out to kill someone or yourself.
It is a great concern to think that people like you keep driving on the road while they try to find a solution to such a serious problem on the internet.

I'd take the car to a reputable car dealership which sells the same brand and tell them the symptoms. You don't want to wait for a catastrophic failure to get it fixed right.
