I have a voice in my car !!! I can't find help

hello my car peugeot bipper 2011 model does not always happen if it slips for a very long time, it sounds like "knock knock" and the pedal knocks my foot, is there a problem?

he is a normal teacher no problem :)

I also rarely have a problem, think that the vehicle is trying to stay idle, is it true that my teacher has a tremor like him. Me too

sudden brake like it hits the abs due to absence or there is a sound like a plug to the pedal. Seyfi DMR 2018-12-14 13:51:58
