High School Revisited:  Your Vehicle’s Brake Components

What were you paying attention to in high school?  Never mind.  We know.  It was likely girls/boys, weekend plans, and the latest “news” (which wasn’t found on CNN).  Chances are, physics lessons and any mechanical knowledge mentioned in driver’s ed aren’t your favorite memories from high school, but they are, nevertheless, part of your everyday life.  How?  If you drive or ride in any kind of transportation, you rely on brakes.  Concerned about your brakes and not remembering those belabored lessons?  That’s okay.  Bring your vehicle to AMPM Automotive in Rockville, Maryland.  We can help you ensure that your brakes are in proper working order –without you having to attend remedial high school classes.

A Few Parts, An Amazing Whole 

So you just press the brake pedal, and the car stops.  Right?  Yes, but the principles and components are a bit more complex than that.  When your auto is rolling, it is primarily governed by Newton’s First Law of Motion.  This states that an object (like your car) that is in motion tends to stay in motion.  Great–until you’re in imminent danger or you’re approaching a stop sign.  Then what?  That’s when your brakes (those parts you can’t see) suddenly become the most important components on your auto.  The braking system works using Pascal’s Principle, meaning that pressure anywhere in a closed system is transferred evenly throughout all the fluid in that system.  Thus, you depress the brake pedal, and the pressure to the brake fluid is applied throughout.  Eventually, this causes friction, the final physics principle that stops your vehicle. 

Here’s how it works:

The force of your foot against the pedal moves a piston into the master cylinder.  This is a reservoir that holds brake fluid.  The piston’s pressure forces brake fluid through hoses to the cylinder near each wheel.  The force multiplies, moving the components and causing friction that ultimately stops the car.  Most modern cars have disc brakes on at least the front wheels.  The forced brake fluid presses the brake caliper.  The caliper then moves the brake pad against the disc.  As these metal parts contact each other, the friction reduces forward motion, causing the car to slow and eventually stop.  Older cars as well as the rear wheels on many newer autos have drum brakes.  They also use friction.  With this type, the force of the brake fluid pushes metal brake shoes against the inner surface of the drum (which turns inside the wheel), causing the car to slow down and stop.  Together, these individual parts form an amazing safety system for modern cars using long-known scientific concepts.

Give Your Brakes a Break 

Obviously, all this force and friction can eventually lead to wear.  If you need your brakes inspected, are ready for preventive maintenance service, or suspect a braking problem, give your hard-working brakes a break.  Bring your auto to AMPM Automotive in Rockville, Maryland.

Title: 5 Essential Car Maintenance Tips Every Driver Should Know

February 19, 2025
1. Regular Oil Changes Why it matters: Oil lubricates the moving parts of your engine, reducing wear and tear. Over time, oil breaks down and gets dirty, which can strain your engine. How often: Typically, you should change your oil every 5,000 to 7,500 miles, but check your vehicle's manual as some newer cars might go up to 10,000 miles between changes. At AMPM Automotive: We use high-quality oils and filters to ensure your engine is in top condition. Book an appointment for your next oil change!  2. Check Your Tire Pressure Why it matters: Incorrect tire pressure can lead to poor fuel efficiency, uneven tire wear, and compromised safety. How often: Check your tire pressure at least once a month and before long trips. The correct pressure is usually found on a sticker inside the driver's door or in the car manual. At AMPM Automotive: We offer free tire pressure checks with any service to ensure your ride is safe and smooth.  3. Replace Air Filters Why it matters: A clean air filter ensures that your engine gets enough air for optimal combustion, which impacts performance and fuel economy. How often: Air filters should generally be replaced every 12,000 to 15,000 miles, but this can vary based on driving conditions. At AMPM Automotive: We check and replace air filters during routine maintenance to keep your engine breathing freely.  4. Battery Maintenance Why it matters: A failing battery can leave you stranded. Regular checks can extend battery life and prevent sudden breakdowns. How often: Inspect your battery every six months. Look for corrosion, loose connections, or signs of wear. At AMPM Automotive: We provide battery testing and replacement services to keep you powered up on the road.  5. Brake System Checks Why it matters: Your brakes are crucial for safety. Wear and tear can lead to reduced stopping power. How often: Have your brakes inspected at least once a year or if you notice any changes in braking performance. At AMPM Automotive: Our expert technicians will ensure your brakes are in top shape, providing peace of mind with every brake service. Conclusion Maintaining your car doesn't have to be a chore; it's about ensuring your safety and the longevity of your vehicle. Here at AMPM Automotive, we're committed to helping you keep your car in prime condition. If you have any questions about car maintenance or need to schedule a service, feel free to reach out to us. Safe driving!
