UNSPSC 25171727: Drum brake wheel cylinder

In a drum brake system, the Wheel Cylinder puts pressure on the brake shoes, which when pressed against the drum, slows down and stops the vehicle. The cylinder is connected to the shoes by small rods.

UNSPSC 25171727 Drum brake wheel cylinder is a Commodity code covering specialized brake components for motor vehicles. State and local governments procure drum brake wheel cylinders as part of broader motor vehicle brake parts buys—typically sourced alongside pads, shoes, rotors, hoses, calipers, and boosters for fleet maintenance and replacement programs. School districts and transit authorities are primary buyers under this code, using wheel cylinders to maintain passenger vehicles, light trucks, medium and heavy-duty trucks, buses, and trailers. Components must be factory-approved and OEM-certified with manufacturer warranties; parts may be new or remanufactured as specified in the solicitation. Suppliers generally must meet compliance requirements such as E-Verify employment verification, drug-free workplace certification, and debarment certification when contracting with public bodies.

Pinellas County School District in Florida issued the most recent representative opportunity, an Invitation for Bids (ITB #26AM016) for Motor Vehicle Brake Parts with bids due August 24, 2026, covering an estimated $190,000 annually across passenger vehicles, light trucks, and heavy-duty vehicles. The district limits suppliers to a 40-mile radius of the Walter Pownall Service Center and applies a 5 percent Florida business preference when the lowest bid originates from an out-of-state supplier whose state does not grant reciprocal preference. The contract runs October 28, 2026 through October 27, 2027 with optional renewals. Geographic activity is concentrated in Florida based on recent solicitation records; other regions show minimal relevant recent opportunities tagged to this specific Commodity code. The Broward County RFI for Bubenzer brake systems and a Sourcewell cooperative procurement for law enforcement equipment do not align with the scope of drum brake wheel cylinders and represent collateral activity rather than direct market signals for this component.
