2017 Nissan Sentra Brake Pads And Rotors

If you're a 2017 Nissan Sentra owner, maintaining your vehicle's braking system is paramount for safety and performance. One of the most critical aspects of brake maintenance is regularly inspecting and, when necessary, replacing your brake pads and rotors. This article provides a comprehensive guide to understanding the brake system in your 2017 Sentra, recognizing the signs of wear, and making informed decisions about replacement.

Understanding Your 2017 Nissan Sentra's Brake System

Your 2017 Nissan Sentra utilizes a hydraulic braking system. When you press the brake pedal, it activates a master cylinder, which sends hydraulic fluid through brake lines to the calipers at each wheel. These calipers then squeeze the brake pads against the rotors, creating friction that slows down and stops the vehicle. Understanding the components and their roles is crucial for proper maintenance.

Brake Pads: These are friction materials pressed against the rotors to slow the car. They're designed to wear down over time.
Rotors: Also known as brake discs, these are metal discs that rotate with the wheels. The brake pads clamp onto them to generate friction.
Calipers: These house the brake pads and use hydraulic pressure to squeeze them against the rotors.
Brake Lines: These hoses carry brake fluid from the master cylinder to the calipers.
Master Cylinder: This component pressurizes the brake fluid when you press the brake pedal.

Signs You Need New Brake Pads and Rotors

Recognizing the signs of worn brake pads and rotors is crucial to preventing accidents and ensuring optimal braking performance. Here are some common indicators:

Squealing or Screeching Noises

One of the most common signs of worn brake pads is a high-pitched squealing or screeching noise when you apply the brakes. Many brake pads have a built-in wear indicator, a small piece of metal that rubs against the rotor when the pad material wears thin. This sound is a warning that it's time to inspect your brakes. Don't ignore it! The sooner you address it, the better. Waiting too long can lead to rotor damage, increasing the cost of repair.

Grinding Noises

If you hear a grinding noise when braking, it's a serious sign that your brake pads are severely worn, and the metal backing plate is rubbing directly against the rotor. This can cause significant damage to the rotors and compromise your braking ability. Continuing to drive with grinding brakes is dangerous and can lead to costly repairs. Immediately have your brakes inspected by a qualified mechanic.

Vibration or Pulsation in the Brake Pedal

A vibration or pulsation in the brake pedal when you apply the brakes can indicate warped or damaged rotors. This uneven surface causes the brake pads to grab intermittently, resulting in the vibration. Warping can occur due to excessive heat build-up from hard braking or uneven wear. While sometimes resurfacing the rotors can fix this, often replacement is the better long-term solution.

Longer Stopping Distances

If you notice that it takes longer to stop your 2017 Nissan Sentra, it could be a sign of worn brake pads or glazed rotors. Worn pads have reduced friction, while glazed rotors have a hardened surface that prevents proper pad grip. This reduced braking efficiency increases stopping distances and poses a safety risk. Regular inspections will help avoid this dangerous situation.

Visual Inspection of Brake Pads

You can visually inspect your brake pads to assess their remaining thickness. Most mechanics recommend replacing brake pads when they have less than 3mm (approximately 1/8 inch) of friction material remaining. You may be able to see the brake pads through the wheel spokes, but removing the wheel provides a clearer view. If you're unsure how to perform this inspection, consult a qualified mechanic.

Pulling to One Side When Braking

If your car pulls to one side when you apply the brakes, it could indicate uneven brake wear or a problem with the calipers. This can be caused by a sticking caliper piston, which prevents the brake pad from applying evenly. This issue can be dangerous and should be addressed immediately by a professional mechanic.

Choosing the Right Brake Pads and Rotors for Your 2017 Nissan Sentra

When it comes to replacing your brake pads and rotors, you have several options to choose from. Selecting the right components depends on your driving style, budget, and desired performance. Here's a breakdown of common types:

OEM (Original Equipment Manufacturer) Brake Pads: These are the same pads that came with your 2017 Nissan Sentra from the factory. They are designed to provide optimal performance and durability for your vehicle. OEM pads are generally more expensive than aftermarket options but offer guaranteed compatibility and reliability.
Aftermarket Brake Pads: There are numerous aftermarket brake pad brands available, offering a range of performance characteristics and price points. Some popular types include:
- Semi-Metallic Brake Pads: These pads offer a good balance of performance and durability. They are suitable for everyday driving conditions.
- Ceramic Brake Pads: Ceramic pads are known for their quiet operation, low dust production, and excellent stopping power. They are a good choice for drivers who prioritize comfort and performance.
- Organic Brake Pads: These pads are made from organic materials and are generally less expensive than other types. They are suitable for light-duty driving but may not offer the same level of performance and durability as semi-metallic or ceramic pads.
Performance Brake Pads: Designed for more aggressive driving and high-performance vehicles. They offer improved stopping power and heat resistance but may produce more noise and dust.
Rotor Options:
- Standard Rotors: These are the most common and affordable type of rotor. They are suitable for everyday driving.
- Drilled and Slotted Rotors: These rotors feature holes and slots that help dissipate heat and improve braking performance, especially in wet conditions. They are often used in performance applications.
- Vented Rotors: Designed to improve heat dissipation, typically equipped on the front.

When choosing brake pads and rotors, consider your driving habits and the type of performance you need. If you primarily drive in city traffic, ceramic pads might be a good option. If you frequently drive on the highway or tow heavy loads, semi-metallic pads might be more suitable.
