If you’re a very cautious driver, you may keep your left foot on the brake pedal instead of on the footrest so that you can slam on it at a moment’s notice. The primary purpose of your brakes is, of course, to slow and stop your car, but that doesn’t mean they should be engaged all the time, especially not while the engine is being revved.
Riding the brake pedal, even slightly, puts unnecessary wear and tear on the brake pads and rotors or drums. The brake and gas pedals are not supposed to be engaged at the same time –- pressing the brakes down while the rotors are spinning full-on causes the brakes to overheat, which in turn reduces their stopping power. If you keep doing this, eventually, you’ll actually increase the likelihood that your brakes will suddenly fail on you while you’re on the road. This can lead to more frequent stops at the mechanic shop or potentially a car accident.
