ACDelco Gold 17D785CH Ceramic Disc Brake Pad Set

The 17D785CH uses the D785 brake-pad geometry and fits GMT800-era full-size GM trucks and SUVs as front pads: 1999-2006 Chevrolet Silverado 1500 and GMC Sierra 1500, 2001-2010 Silverado/Sierra 2500HD and 3500HD, 2000-2006 Tahoe, Yukon, Suburban, Avalanche, and 2002-2006 Cadillac Escalade/ESV/EXT, plus 2003-2009 Hummer H2. Always verify your exact year, make, model, and brake package against the current ACDelco fitment guide before buying. A newer variant (17D785CHF1) covers additional applications and adds a hardware clip kit.

Yes. The manufacturer feature bullets confirm the set ships with premium shims, slots, and chamfers to reduce noise, vibration, and braking harshness. The stamped backing plate is also designed to allow proper pad movement within the caliper assembly. The 'CH' suffix on the part number typically denotes included hardware for ACDelco. A newer variant (17D785CHF1) adds a separate abutment-clip kit; if your application uses abutment clips, the CHF1 may be the more complete choice.

The SAE J866 friction edge code is not publicly disclosed by ACDelco for the 17D785CH. The edge code, which tells you the cold and hot friction coefficients (e.g., FF, GG), is stamped on the physical pad edge but is not listed on the product page or any accessible spec sheet. Physical inspection of the pad is required to read it. ACDelco Gold ceramic compounds are positioned for OE-equivalent daily-driver performance, but the specific code is unconfirmed from public sources.

ACDelco Gold ceramic brake pads are marketed with a low-copper formula, and ACDelco Canada's product pages reference a LeafMark on the packaging indicating compliance with the California SB 346 and Washington Better Brakes laws. However, the specific A, B, or N marking (which indicates the restriction level) has not been confirmed for part number 17D785CH from any publicly accessible document. The ceramic compound class inherently sheds lighter metallic dust than semi-metallic compounds.

The Amazon listing for ACDelco Gold 17D785CH Ceramic Disc Brake Pad Set carries a California Prop 65 warning. California requires this warning on a very wide range of manufactured goods — including rubber, vinyl, plastic, and metal automotive parts — whenever trace exposure to any of roughly 900 listed substances (commonly phthalates or heavy metals) is possible, regardless of whether the specific product poses a meaningful health risk. As a passive accessory, ACDelco Gold 17D785CH Ceramic Disc Brake Pad Set has no Safety Data Sheet, so there's no chemistry breakdown to translate beyond that.
