ACDelco 17D821MH Gold Semi-Metallic Disc Brake Pad Set

The ACDelco 17D821MH is a Gold Semi-Metallic Disc Brake Pad Set engineered as a high-quality aftermarket alternative to Original Equipment (OE) brake pads. Backed by General Motors, these semi-metallic brake pads are formulated with steel strands to deliver premium stopping power while efficiently conducting heat away from the rotor's surface — helping to protect both pads and rotors under demanding braking conditions.

Key Features:

• Semi-metallic friction formula with steel strands for strength, heat dissipation, and consistent braking performance
• Integrally molded friction material bonded directly to the backing plate for superior bond integrity
• Stamped backing plate allows proper pad movement within the caliper assembly, reducing noise and brake pulsation
• Premium shims, slots, and chamfers help diminish noise, vibration, and braking harshness (NVH)
• Noise-dampening shims included where applicable for a quieter braking experience
• No curing required — ready to install straight out of the box
• Independently tested to SAE J2784 and D3EA standards for braking effectiveness, NVH, durability, and wear
• Engineered to resist corrosion and premature wear
• Manufactured to meet fit, form, and function specifications for GM vehicles and most other makes and models

ACDelco Gold brake pads are the GM-backed aftermarket choice for drivers who want dependable braking performance without sacrificing quality. Some ACDelco Gold parts may have formerly appeared under the ACDelco Professional name.
