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.

Keep Your Electric Vehicle Running Smoothly with AMPM Automotive As electric vehicles (EVs) surge in popularity across Rockville, MD, and beyond, understanding their maintenance needs is key to ensuring they perform at their best. Unlike traditional gas-powered vehicles, EVs have fewer moving parts and don’t require oil changes or tune-ups, which means lower maintenance costs and fewer trips to the shop. However, they still need regular care to maintain safety, efficiency, and longevity. At AMPM Automotive, we’re proud to offer expert EV maintenance services to keep your electric vehicle in top condition. Here’s what you need to know about maintaining your EV and why AMPM Automotive is your trusted partner in Rockville. The Benefits of EV Maintenance EVs are designed with simplicity in mind, eliminating many of the components found in internal combustion engine (ICE) vehicles, such as spark plugs, oil filters, and transmissions. This results in fewer maintenance tasks and significant cost savings over time. Research suggests EV owners spend roughly one-third of what ICE vehicle owners do on regular maintenance (MYEV.com). Additionally, EVs use regenerative braking, which reduces wear on brake pads, further extending their lifespan. Despite these advantages, regular maintenance is still essential to ensure your vehicle’s warranty remains valid and to prevent unexpected issues. Common EV Maintenance Tasks While EVs require less frequent maintenance, several key tasks are necessary to keep them running smoothly. Here’s a breakdown of the most common maintenance needs: Tire Maintenance : Properly inflated tires improve your EV’s range and safety. Regular tire rotations and inspections for wear are crucial, especially since EVs can be heavier due to their batteries, which may affect tire longevity. Brake Inspections : Regenerative braking reduces wear on traditional brakes, but they still need periodic checks to ensure they function correctly. A trained technician can assess brake pad condition and fluid levels. Coolant Checks : Many EVs use coolant to regulate battery temperature. Checking coolant levels and condition as per the manufacturer’s guidelines is essential to prevent overheating and maintain battery health. Cabin Air Filter Replacement : Like ICE vehicles, EVs have cabin air filters that need periodic replacement to ensure clean air inside the vehicle, typically every 20,000 miles or two years. Battery Health Monitoring : EV batteries are sealed and don’t require direct maintenance, but monitoring their health through diagnostic systems is vital. Most manufacturers offer 8-year/100,000-mile warranties for EV batteries, ensuring long-term reliability (Alternative Fuels Data Center). Software Updates : EVs often receive over-the-air software updates to enhance performance, range, and features. Keeping your vehicle’s software current is a simple yet critical maintenance task.

Practical Tips for EV Owners To maximize your EV’s performance and lifespan, consider these tips: Optimize Charging Habits : Avoid letting your battery drop below 20% regularly, as this can impact long-term battery health. Aim to keep your charge between 20% and 80% for daily use to reduce stress on the battery. Use Genuine Parts : When replacements are needed, opt for manufacturer-recommended parts to ensure compatibility and maintain your vehicle’s performance. Adhere to Maintenance Schedules : Follow the maintenance schedule outlined in your owner’s manual to keep your warranty valid and your EV in peak condition. Plan for Range Variations : Be mindful of your vehicle’s range, especially in extreme weather, which can affect battery performance. Plan trips accordingly to avoid running low on charge.
