Why New Rotors (or Resurfaced Ones) Are a MUST with New Brake Pads

Squealing brakes? Grinding noises? Reduced stopping power? Chances are, you need new brake pads. But what about those rotors? Often overlooked, your brake rotors play a critical role in your vehicle’s stopping performance. At AES, we believe in doing the job right, and that means paying close attention to the condition of your rotors when replacing your brake pads. Let’s dive into why you should always consider rotor replacement or resurfacing during a brake job.

What are Brake Rotors and Why Are They Important?

Simply put, brake rotors (also sometimes called brake discs) are the shiny, metal discs that your brake pads clamp onto to slow down or stop your vehicle. When you press the brake pedal, hydraulic pressure forces the calipers to squeeze the brake pads against the rotor. The resulting friction generates heat, slowing the rotor’s rotation and, consequently, the wheels.

Because of the immense friction involved, rotors are subject to significant wear and tear over time. Just like brake pads, they are a wear item and require periodic replacement or resurfacing.

The Dangers of Using Old Rotors with New Brake Pads

Here’s the crux of the matter: putting new brake pads on worn or damaged rotors is like putting new tires on bent rims – it just doesn’t make sense and can be dangerous! Here’s why:

• Uneven Wear and Reduced Braking Performance: Old rotors often have uneven surfaces, grooves, or “hot spots.” These imperfections prevent the new brake pads from making full, consistent contact with the rotor surface. This leads to reduced braking power, longer stopping distances, and potentially dangerous situations, especially in emergencies.
• Premature Brake Pad Wear: The uneven surface of the old rotor will cause the new brake pads to wear unevenly as well, shortening their lifespan and costing you more money in the long run. You might find yourself back in the shop much sooner than expected.
• Increased Noise and Vibration: Worn rotors can cause annoying squealing, grinding, or pulsating sensations when braking. These noises and vibrations indicate that your braking system isn’t functioning optimally and should be addressed immediately.
• Potential Damage to Calipers: Severely warped or damaged rotors can put undue stress on the brake calipers, potentially leading to more expensive repairs down the line.

Rotor Resurfacing vs. Rotor Replacement: Which is Right for You?

When your rotors are worn, you have two options: resurfacing (also known as “turning” or “machining”) or replacing them entirely.

Rotor Resurfacing:

Resurfacing involves using a specialized lathe to shave a thin layer off the rotor surface, creating a smooth, even surface for the new brake pads to contact. This is a viable option if the rotors are still within the manufacturer’s specified thickness tolerances and are free from deep cracks or excessive damage. Resurfacing is generally more cost-effective than replacement.

Rotor Replacement:

Replacing the rotors is the preferred option if the rotors are too thin, have deep cracks or grooves, or are severely warped. While it’s generally more expensive upfront, replacing the rotors ensures optimal braking performance and longevity. At AES, we often recommend replacement for optimal safety and performance.

How AES Can Help

At AES, our experienced technicians will thoroughly inspect your brake rotors to determine the best course of action. We use state-of-the-art equipment to accurately measure rotor thickness and identify any signs of damage. We’ll then provide you with an honest assessment and recommend either rotor resurfacing or replacement based on the specific condition of your rotors and your vehicle’s needs. We only use high-quality brake pads and rotors to ensure long-lasting performance and your complete satisfaction.

The Bottom Line: Don’t Neglect Your Rotors!

Replacing your brake pads without addressing the condition of your rotors is a recipe for disaster. It can compromise your safety, reduce braking performance, and lead to premature brake pad wear. Protect yourself and your vehicle by having your rotors inspected and either resurfaced or replaced whenever you get new brake pads. Contact AES today to schedule a brake inspection and ensure your vehicle’s braking system is in top condition. Your safety is our priority!
