Brake-disc RFQ: complete the geometry before comparing unit prices

A diameter-only reply leaves most of a brake-disc request unanswered. Preserve the authorized application and separate diameter, nominal thickness, height, centering, hole geometry and construction. Dimensional agreement can clarify an offer; it cannot establish braking performance or authorize use.

Define the purchasing decision

Name the source, units and feature behind each required dimension. A minimum-thickness service field is not the nominal dimension of a new purchase. A hole count is not a complete hole pattern. Ask the supplier to map its terminology to the authorized reference rather than aligning columns merely because the numbers look similar.

Compare the supplier replies

Illustrative offers: A answers diameter only. B supplies several dimensions but labels thickness with a service-limit term. A needs the remaining geometry; B needs the field meaning clarified. If clarification reveals a different nominal requirement, retain a changed proposal rather than waiving it as a clerical issue. Keep actual pieces per quoted unit separate from technical acceptance.

Original buyer worksheet

Source and scope

Brembo’s current official Czech document for 09.F363.11 separates nominal and minimum thickness, height, centering, hole count, axle and box quantity. It is a documentary field example, not a complete drawing or an application recommendation for another disc. Official manufacturer source (Czech).

Keep procurement approval and technical acceptance separate. A quotation, complete pack or matching photograph does not establish fit, safety, durability or permission to install. The responsible product or service provider must resolve application questions. Named manufacturer examples illustrate documents; they are not supply offers, affiliations or validation of an unnamed alternative.

Prepare a reviewable request

Quote the released reference and complete geometry with units and field meanings. Identify construction, actual pieces priced, any deviation and product-specific evidence still awaiting technical review. Reference and approved revision: [ ]. Required quantity and unit: [ ]. Destination: [ ]. Available photos or source documents: [ ]. Please mark exclusions, deviations and missing evidence separately from the price.

Keep the supplier’s exact reference and dated reply with the approved scope. Ask for a revised consolidated quotation if a later message changes contents, configuration or unit. Record product price, applicable MOQ, packing and lead time as the supplier’s response to this request, not as a general promise. Independent buying coordination does not replace the responsible technical decision.

Buyer questions

What should be clarified before the price is compared?

Name the source, units and feature behind each required dimension. A minimum-thickness service field is not the nominal dimension of a new purchase. A hole count is not a complete hole pattern. Ask the supplier to map its terminology to the authorized reference rather than aligning columns merely because the numbers look similar.

Can this worksheet approve a part or a repair?

No. It organizes the purchasing evidence and the supplier’s unanswered questions. Technical acceptance, repair scope and installation remain separate decisions for the responsible qualified provider.
