The Significance of Mechanical Attachment in Brake Pad Design
Friction material attachment to the backing plate is a crucial aspect of brake pad design, directly impacting brake functionality and safety. In this article, we will delve into the importance of mechanical attachment in brake pad design, comparing original equipment (OE) pads with aftermarket alternatives.
Key Elements of Brake Pad Design
Four fundamental elements of brake pad design play a critical role in ensuring optimal brake performance and safety:
- Rust protection for the backing plate: Prevents corrosion and maintains the integrity of the brake pad.
- Attachment method of friction material to the backing plate: Determines the strength and durability of the bond between these components.
- Flatness of the backing plate: Ensures proper contact between the brake pad and the rotor, reducing noise and vibration.
- Tolerances of the abutment areas: Allows the brake pads to slide smoothly within the caliper, preventing binding and premature wear.
Focus on Friction Material Attachment
In this article, we will focus specifically on the attachment of the friction material to the backing plate. We will examine five different brake pads: one OE pad, one from NRS Brakes, and three from various aftermarket companies.
Mechanical Attachment vs. Adhesive Bonding
The primary distinction between OE and certain aftermarket brake pads lies in the attachment method. OE pads and NRS Brakes pads employ mechanical attachment, utilizing hooks to create a secure bond between the friction material and the backing plate. This method is particularly crucial for applications involving high heat, as heat can degrade adhesives, compromising the integrity of the brake pad.
Surprisingly, some aftermarket brake pads, despite being designed for the same vehicle, lack this essential mechanical attachment feature. This oversight can have severe safety implications, especially in high-temperature scenarios.
Conclusion
The choice of brake pads significantly impacts vehicle safety and performance. By understanding the importance of mechanical attachment in brake pad design, drivers can make informed decisions when selecting replacement brake pads. Opting for OE or reputable aftermarket brands that employ mechanical attachment ensures optimal braking performance and longevity.
