ACDelco 17D225MB Gold Semi-Metallic Disc Brake Pad Set with Hardware

The ACDelco 17D225MB is a Gold (formerly Professional) Semi-Metallic Disc Brake Pad Set engineered as a high-quality alternative to Original Equipment (OE) brake pads. Formulated with steel strands, these semi-metallic pads deliver premium stopping power while efficiently conducting heat away from the rotor surface — helping to protect both the pads and rotors during demanding braking conditions.

Key Features:

• Semi-metallic friction formula — steel strand construction provides strength and superior heat dissipation for consistent braking performance
• Integrally molded friction material — bonded directly to the stamped backing plate for maximum bond integrity and durability
• Stamped backing plate — allows for proper pad movement within the caliper assembly, reducing noise, brake pulsation, and premature wear
• Premium shims, slots, and chamfers — engineered to diminish noise, vibration, and braking harshness (NVH)
• No break-in or curing required — ready for immediate installation right out of the box
• Tested to SAE J2784 standards — independently verified for braking effectiveness, NVH performance, and durability
• Backed by General Motors — manufactured to meet GM specifications for fit, form, and function across GM vehicles and most other makes and models

The ACDelco Gold brake pad lineup — which may have formerly appeared under the ACDelco Professional name — goes through a rigorous quality approval process to ensure reliable, confident stopping power. The 17D225MB includes hardware where applicable, making it a complete replacement solution for disc brake service.
