There are times trying to explain perception with keyboard is rather difficult. He most probably could not understand what perception is all about. There are times I drive without the stereo on so that I can have a better perception of my engine noise and exhaust note. They didn't get louder but I hear them clearer and louder once I turn my stereo down. Same thing after changing from the super noisy Goodyear F1 GSD3, which anybody with any interest in cars and tyre would know they are noisier than hell. It was like turning my stereo down a couple of notches.. engine noise because clearer and the perception of noise became louder. The exhaust burble is perceived as louder but of course the db stayed the same. Just that we have less interfering noise to content with.

Leg break controls the brakes with cable and your brake pedal control with hydraulic pressure. There will be a difference in the brake force applied between the brake pedal and leg break and in that transition from brake pedal to leg brake cable, you get the 'earth move under your car' feeling. This happens to most large cars as there is more weight settling in during the transition. Should not be anything to be worried about.

You can always bring it to them to tighten the leg-brake cable. My handbrake is so tight that if I were to pull it while driving, it locks the rear wheels immediately and I don't have that issue as the pressure from my handbrake is just as strong as my rear brakes. I don't drive the same car you do. I have felt those sensations in much larger and older vehicles and in some cars with rear drum brakes.
