UNSPSC 25171735: Brake lining

A brake lining is friction material attached to the face of a brake shoe, to cause frictional force when the brake shoe makes contact with the brake drum.

UNSPSC 25171735 Brake lining is a Commodity code that encompasses discrete brake system components and assemblies — linings, pads, calipers, drums, rotors, and related hardware — that state and local transit authorities, school districts, and municipal fleet operators procure for routine maintenance and emergency repair of buses, trucks, and specialized vehicles. Recent solicitations show procurement of individual brake subassemblies (rear disc brake calipers without lining), king pin kits for front axles, hub and bearing assemblies, and comprehensive parts packages bundled with brake and suspension components for multi-year supply agreements. The issuing bodies are primarily transit authorities and school districts managing large bus fleets: the Dallas Area Rapid Transit Authority (DART) in Texas dominates the recent activity with frequent short-cycle purchase orders for discrete components, while the Charlotte Area Transit System (CATS) in North Carolina, the Broward County Transportation Department in Florida, and multiple Missouri school districts (Parkway School District, Rockwood School District) solicit for broader brake-and-suspension or brake-specific parts packages. The Town of Manchester, Connecticut, and Dallas County also appear as buyers, indicating the code spans urban and regional transit operations as well as school district fleet maintenance.

Geographic concentration is heaviest in Texas, particularly through DART's repeated sourcing, with secondary activity in North Carolina, Florida, Missouri, and Connecticut. DART's purchasing pattern reflects its status as a high-volume transit operator with compressed bidding windows (typically three to five calendar days) and standing purchase order frameworks; CATS issued an Invitation to Bid on March 25, 2026 (due May 13, 2026) for over 600 line items of brake and suspension parts to support 246 buses and 95 paratransit vehicles under a five-year initial term with two optional one-year extensions, while Broward County Transportation Department solicited comprehensive Cummins engine and chassis system repair services (including brake systems) on May 8, 2026 (due June 1, 2026) as an open-end indefinite quantity contract with requirements for authorized service facilities, dyno testing, and extended warranties. School district procurement emphasizes standardized OEM parts lists with fixed pricing and local delivery capability — Parkway School District sought bus and vehicle OEM parts on a blanket purchase-order basis due May 19, 2026, and Rockwood School District solicited 2026–2027 bus and fleet vehicle parts due April 9, 2026. No set-asides or preferences specific to the code tier appear in the opportunities, though federal Buy America and DBE compliance requirements apply where FTA funding is present.
