Expert Tip: Choosing Between Coated and Non-Coated Brake Pads

Expert Says:

When it comes to brake pads, the difference between coated and non-coated is more than just a cosmetic detail. Coated brake pads feature an anti-corrosion layer that protects against rust, improves durability, and ensures consistent braking performance—especially in regions with harsh winters, salted roads, or high humidity. They also provide a cleaner installation with less brake dust buildup over time.

Non-coated brake pads, on the other hand, are cost-effective and reliable under normal driving conditions. However, they may wear faster when exposed to moisture, road salt, or heavy loads, making them less suitable for demanding climates or long-term durability.

Expert insight: If your vehicle operates in areas with snow, rain, or salted highways, investing in coated brake pads can extend the lifespan of your braking system, reduce noise, and improve overall safety. For everyday use in mild environments, non-coated pads remain a solid budget-friendly option.

Bottom line: Coated pads = premium protection & performance. Non-coated pads = value-focused everyday driving.

Expert Tip: Why Are There So Many Brake Pad & Rotor Brands?

Expert Says:

When shopping for brake pads or rotors, it might feel overwhelming to see dozens of different brands with varying prices. The truth is: the core technology behind most braking components is very similar. Many brands source their parts from the same OEM or Tier-1 manufacturers, then repackage and market them under different labels.

So, do we really have thousands of unique quality levels? Not exactly. The differences are often in the details—such as coating type, noise-reduction shims, packaging, or warranty support. While premium lines may use enhanced materials or special coatings for longer life and quieter performance, many mid-range options are essentially the same product offered at different price points.

Bottom line: The wide variety of brands is driven more by marketing and positioning than by massive differences in core quality. For most drivers, choosing a reputable supplier and ensuring proper installation matters far more than chasing every “new” brand name on the shelf.

Expert Tip: The Importance of Proper Brake Pad Installation

Expert Says:

Even the best brake pads will underperform if they’re not installed correctly. Proper installation ensures even contact with the rotor, reduces the risk of premature wear, and most importantly—eliminates unwanted noise or vibration. A poorly aligned pad or missing hardware can lead to squealing, grinding, or uneven braking that compromises both comfort and safety.

Expert insight: Always make sure new pads are installed with fresh shims, clips, and proper torque settings. Professional installation not only guarantees optimal performance but also prevents common issues like brake squeak, excessive dust, or rotor damage. In the long run, this saves money and extends the life of your braking system.

Bottom line: Correct installation = quiet, safe, and long-lasting brakes. Cutting corners during installation almost always leads to noise, reduced performance, and higher costs down the road.
