Philippe, The only way the situation can change from one side to the other is if the first side that is locking is getting hot first. As that side experiences "brake fade" from the overhot condition, then the other side becomes more effective. I do not like Kanter hose quality. I would like to see someone go to a street rod supplier making steel braided hoses and get a quantity made for our cars. I care more for safety than authenticity. Wayne
