How to choose pads
Choosing the right brake pads for your 2014 Kenworth T680 is crucial for optimal braking performance, longevity, and safety. Given the heavy-duty nature of the T680, commercial-grade brake pads are essential. Here’s a breakdown of common types:
- Ceramic: While popular in passenger vehicles for quiet operation and low dust, ceramic pads for heavy-duty trucks are designed for demanding applications. They offer excellent stopping power and are resistant to fade, making them a good choice for long hauls and varied driving conditions. They often have a longer wear life than semi-metallic pads in certain applications.
- Semi-Metallic (Semi-Met): These are a very common choice for heavy-duty trucks like the T680. Semi-metallic pads offer excellent braking performance across a wide range of temperatures and provide good pedal feel. They are known for their durability and ability to dissipate heat, crucial for heavy loads and frequent braking. They can be noisier and produce more dust than ceramic pads.
- Heavy-Duty (HD) / Severe-Duty: These pads are engineered for the most rigorous applications, such as vocational trucks, buses, and severe-duty commercial vehicles. They are designed to withstand extreme temperatures, heavy loads, and prolonged braking, offering maximum stopping power and resistance to fade. They often employ unique friction materials and construction for enhanced durability. For a 2014 Kenworth T680, especially if it
