Brake Pad Materials Compared: Organic, Semi-Metallic, and Ceramic
Not all brake pads are created equal. The compound used in the friction material determines how your brakes perform, how long they last, how much dust they generate, and how quiet they are. Here's how the three main types compare.
Organic (NAO) Brake Pads
Non-asbestos organic (NAO) pads are made from materials like rubber, glass, fiber, and Kevlar mixed with binding resin. They're the softest compound and generate the least noise and brake dust. Tradeoffs include lower heat tolerance and faster wear under spirited or heavy driving.
Semi-Metallic Brake Pads
Semi-metallic pads contain 30–65% metal content (steel wool, wire, iron powder) mixed with friction modifiers. They offer better heat dissipation and longer life than organics, making them the standard choice for trucks, towing, and drivers who want solid all-around performance.
Ceramic Brake Pads
Ceramic pads use ceramic fibers and copper filler to create a compound that generates light-colored, fine dust rather than dark metallic dust. They're among the quietest compounds, gentler on rotors, and excellent for everyday driving. They're not the best choice for performance track use but are ideal for most passenger vehicles.
| Type | Noise | Dust | Heat Tolerance | Rotor Wear | Best For |
|---|---|---|---|---|---|
| Organic | Very low | Moderate | Low | Low | Light daily driving, older vehicles |
| Semi-metallic | Moderate | Higher | High | Moderate | Trucks, towing, performance |
| Ceramic | Low | Very low | Moderate-high | Very low | Daily drivers, clean wheels |
For most Newbury Park commuters, ceramic brake pads offer the best combination of quiet operation, low dust, and long life. We stock premium ceramic pads from top-tier brands.
What About Performance or Track Pads?
High-performance pads use compounds that require heat to reach optimal performance. They can be noisy and generate significant dust in street use. Unless you regularly track your vehicle, performance pads are a tradeoff with minimal benefit for daily driving.

Frequently Asked Questions
Should I replace all four brake pads at once?
Front and rear pads wear at different rates, so replacing all four simultaneously isn't always necessary. However, pads on the same axle should always be replaced as a pair to maintain even braking force.
Can I mix pad types front and rear?
Yes — it's common to use ceramic pads in the front (where most braking occurs) and semi-metallic in the rear. Our technicians can recommend the best combination for your specific vehicle.
Why do my new brakes squeak?
New brake pads often squeal during the first 100–200 miles of break-in as the pad surface conforms to the rotor. This is normal. If squealing persists beyond break-in, the pads may need anti-squeal compound or shim replacement.
