All components and systems inside your Nissan Altima contribute to its aesthetics, functionality and safety. However, its brakes are among the most critical. Keeping them healthy is key to safe driving in any weather. If you suspect that your Altima needs a brake replacement or just want to learn more about its braking system, keep reading for some great information and tips.
Disc Brakes Vs. Drum Brakes
Before delving into your Altima’s braking system, it’s worth taking a quick look at the difference between disc and drum brakes. Disc brakes use disc-shaped spinning metal rotors. A pair of brake pads attached to calipers squeeze each rotor on both sides. This pauses the rotors’ spinning motion, bringing your vehicle to a complete stop. Drum brakes, on the other hand, rely on small round drums with brake shoes inside each drum. When you press the brake pedal, the shoes press against the sides of the drum to stop the vehicle.
Your Altima likely uses disc brakes, which means you must purchase the appropriate rotors and pads when you perform a brake replacement. As you shop for parts, make sure you have the correct model type for your vehicle. The 2017 Altima SR, for example, offers both 4- and 6-cylinder engine options whereas the 2017 Altima S only comes in the 4-cylinder version. It’s a minor difference, but this information ensures that you find the exact components for your vehicle.
Hydraulics and the Master Cylinder
Of course, brakes pads and rotors aren’t the only components in your Altima’s braking system. Pressure must be applied to make the calipers and pads squeeze the rotors and generate enough friction to stop the vehicle. Hydraulic fluid flows through pipes and into cylinders located next to the brakes: It helps apply the necessary pressure for the calipers and pads to do their jobs. That fluid comes from the master cylinder, engaged by a piston that’s pushed by a lever when you press your brake pedal.
Common Brake Problems and Symptoms
Your Altima’s brakes involve a complex assembly of components, plus the conversion of kinetic energy to thermal energy as they stop the car. All these moving parts work seamlessly when they’re healthy, but they can wear out or develop faults over time. Several warning signs can let you know when it’s time for service or total replacement:
- Brake warning light on your dash
- Soft or mushy sensation when you push the pedal
- Your vehicle taking longer to stop
- Clicking, grinding or squealing noises
- Vehicle vibrating when brakes are applied
- Vehicle pulling to one side when you brake
Even if you don’t experience these symptoms, it’s wise to replace your brakes when your owner’s manual recommends it. Depending on how much you drive, this may happen every 20,000 or 30,000 miles.
A Few Last Words About Brake Maintenance
As you care for your Altima’s braking system, keep in mind that your driving habits will dictate how often you must service or replace its brakes. Usually, it’s a good idea to check them every time you change the oil or rotate your tires. Whether you need new brake pads or Nissan Altima oil filters, don’t forget to purchase your components from a trustworthy retailer.
