In todays modern vehicle we take for granted over 100 years of brake development. Most people don't even know their vehicle has a brake booster since its standard equipment these days. In the early 1920's when the first hydraulic brakes were invented based on Pascal’s law of hydraulics. Pascal’s law states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container. What this did was allow each brake caliper to apply equal pressure to the brake pads on each wheel. This was a huge leap in vehicle safety standards and braking performance. Unfortunately, with this help of the hydraulic pressure from the master cylinder, the brake peddle itself became much stiffer and "heavier" feeling. Previously with tradition cable brakes, the feedback was felt instantly and direct since you had physical cables going to each of the Brake Calipers. This was very inefficient and would never stand up to the acceleration and required deceleration of todays modern vehicles.
Without having the Brake Booster, your brake peddle would be extremely hard to press and stop the vehicle. Most Brake Boosters takes the vacuum your engine makes under deceleration and helps amplify the force/pressure in the hydraulic lines. Because of this, you get that nice squishy feeling on your brake peddle when there is no load on them trying to stop. Then, when your trying to slow down your vehicle the brake booster kicks into action by applying pressure throughout the brake system, allowing you to control the amount of pressure placed on the brake peddle and come to a stop.
Since we all are very familiar with how our brake peddles feel when the engine is running. You can do a quick test to see how your vehicle would feel if it didn't have a power brake booster. While the engine is off, simply pump your brakes a few times. Now, try pushing the peddle down. You will see the pressure to move it just a tiny bit is extremely hard. This is how your brakes would feel driving without the Brake Booster. So although its as glorious as a Big Brake Kit, your Brake Booster is still a very important, vital part in your vehicle safety equipment.
