A wrong brake pad shipment is not limited to receiving a completely different pad shape. The wrong formulation, shim, sensor, edge code, brand label or packaging revision on a familiar shape can also make a shipment unusable for its intended market. Risk falls when the order, sample, production and shipment share one controlled product identity.
1. Do not use a cross-reference as the only identity
OE references, FMSI numbers, supplier numbers and customer SKUs can have many-to-many relationships. Use a stable internal SKU as the purchasing key and link it to the pad shape or drawing revision, material specification, hardware, destination and packaging revision. When references change, preserve the historical mapping and effective date instead of overwriting it.
2. Define the scope of sample approval
An appearance sample, dimensional sample and proposed production sample serve different purposes. The approval record should list the sample identifier, customer SKU, supplier number, specification revision, material specification identifier, hardware, marking, packaging and open items. Our sample approval checklist can help organize the evidence. Signing for receipt of a sample should not mean that every performance and market requirement is approved.
3. Use a golden sample with controlled documents
Both parties may retain an identified and dated reference sample for comparison of appearance, construction and agreed features. A physical item can age or suffer damage and cannot express every formulation, test and regulatory requirement. The order should still reference approved revisions of the specification, material plan, hardware list, artwork and packaging files rather than relying on “make as sample.”
4. Freeze revisions before order release
The purchase-order attachment should provide a line-by-line list of quantity, sales unit, product revision, material revision, hardware, brand, label, carton specification, barcode data and target date. If a required field remains unresolved, hold that SKU from production rather than allowing an old chat message or quotation note to fill the gap.
5. Maintain batch links during production
The supplier should be able to associate the production batch with the work order, material specification, agreed process records, marking and packaging records. Buyers need not request irrelevant proprietary information, but should agree in advance on required traceability fields and retention. A system certificate alone does not establish that a particular carton received the correct material or label.
6. Design pre-shipment checks around likely errors
A generic “appearance passed” result is not enough to prevent mix-ups. Under an agreed inspection method, check:
- Pad shape, key dimensions and pieces per set against the order SKU;
- Shims, wear sensors, clips and other hardware;
- Edge code, brand, label, barcode and packaging revision;
- Inner quantity against outer-carton SKU, batch and carton number;
- Packing list and invoice lines against physical carton counts.
Sampling, equipment, acceptance criteria and responsibilities must be defined for the project. This guide does not prescribe one sampling number for all brake pads.
7. Build a shipment evidence pack
The shipment record can include identifiable photographs of representative products and hardware, barcode scan results, carton-number ranges, pallet manifests, loading photographs, seal number and the final packing list. Evidence should link to the order and batch rather than consist of one generic finished-product image.
8. Return changes to the approval process
When material, construction, hardware, source, marking or packaging changes, describe the reason and affected scope before deciding whether documents, samples or validation must be repeated. AIAG’s public PPAP overview emphasizes consistent fulfillment of engineering design records and specification requirements during actual production. If a customer requires PPAP, manage its scope separately; an ordinary golden sample should not be described as completed PPAP.
Create an actionable error-prevention list
Organize internal SKUs, references, current revisions, sample status, hardware and packaging files, then discuss them with BAOTAI through the inquiry form or review our OEM and private-label services. Fitment, inspection, traceability and release conditions must be confirmed in writing for the specific project.
