Here's a simplified explanation of how the brake system works:
1. When you press the brake pedal, you are essentially activating a master cylinder.
2. The master cylinder then sends brake fluid through brake lines to each of the four wheels.
3. At each wheel, the brake fluid enters a caliper, which contains pistons that push brake pads against the brake rotors.
4. The friction between the brake pads and rotors causes the wheels to slow down and eventually come to a stop.
So, yes, when you push on the brakes, all four tires will engage with the brake system and come to a stop.
