Fifteen years ago (or so) I hired a new Megane in France (78 km only), and the brakes were utterly shocking.
When cold they would chuck you through the windscreen with the lightest touch on the pedal. And an electric parking brake, useless.
BUT when I really needed them on the motorway at 130kph and the whole lot stopped, I was glad to have been in the slow lane and a good 200m behind the car in front, because by the time I was down to 20kph they had no stopping power to speak of and I ended up on the hard shoulder next to the car in front. That driver merely wound down the passenger window, smiled, shrugged and commented “C’est normale avec le Megane.”
When I arrived at our lodgings I phoned the hire company who apologised profusely and sent out a mechanic with much harder pads, their normal change from the factory issue. Somehow it had slipped through their acceptance checks.
