| 1 | High | Product and vehicle coverage | Check the application catalogue, vehicle fitment data, left/right variants, piston diameter, mounting configuration, and reference part numbers. | Complete technical drawings and traceable fitment data should be available before quotation. | 0–10 points |
| 2 | High | Quality management system | Request current certificates, certificate scope, issuing body, expiry date, and recent audit status. | ISO 9001 is a useful baseline; IATF 16949 is a stronger indicator for automotive production controls. | 0–10 points |
| 3 | High | Regulatory and market compliance | Confirm whether the caliper is intended for markets requiring specific braking regulations, type approval, or aftermarket conformity documentation. | Compliance evidence must match the exact product family and target market; generic certificates are insufficient. | 0–10 points |
| 4 | High | Material and corrosion protection | Review housing material, piston material, coating system, surface treatment, salt-spray method, and corrosion acceptance criteria. | Material certificates and documented corrosion-test results should be available for the quoted model. | 0–8 points |
| 5 | High | Hydraulic sealing performance | Check seal material, pressure-testing procedure, leakage limits, temperature range, and test records. | Each production batch should have documented pressure and leakage inspection according to the manufacturer’s control plan. | 0–10 points |
| 6 | High | Dimensional and functional testing | Verify piston travel, mounting dimensions, bleeder position, pad clearance, sliding action, and compatibility with the specified brake system. | Use approved drawings and first-article inspection reports rather than catalogue descriptions alone. | 0–10 points |
| 7 | Medium | Production capability | Assess casting or forging capability, machining equipment, assembly lines, automated inspection, capacity planning, and process traceability. | A capable supplier can explain critical process controls and provide capacity data for peak demand periods. | 0–8 points |
| 8 | Medium | Quality inspection and traceability | Review incoming inspection, in-process checks, end-of-line testing, batch codes, nonconformance procedures, and recall traceability. | Product identification should link the finished caliper to production date, lot, material, and inspection records. | 0–8 points |
| 9 | Medium | Sampling and validation support | Compare sample availability, prototype capability, test-plan support, engineering response, and willingness to modify tooling or specifications. | Before mass production, approve samples using dimensional, functional, and vehicle-level validation where applicable. | 0–7 points |
| 10 | Medium | Lead time and minimum order quantity | Separate sample lead time, standard production lead time, tooling lead time, and minimum order quantity from stock availability. | Compare like-for-like terms: same product complexity, packaging requirement, order quantity, and delivery location. | 0–7 points |
| 11 | Medium | Warranty and after-sales process | Review warranty duration, claim response time, failure-analysis procedure, replacement policy, and responsibility for verified defects. | Prefer written warranty terms with clear evidence requirements and corrective-action deadlines. | 0–6 points |
| 12 | Low | Total landed cost | Include unit price, tooling, testing, packaging, freight, duties, inspection, warranty exposure, and inventory cost. | The lowest unit price is not necessarily the lowest total cost when quality risk and delivery variation are included. | 0–8 points |
| 13 | Low | Packaging and logistics | Check protective packaging, moisture control, labelling, pallet standards, barcode support, and export-document accuracy. | Packaging should prevent piston, coating, mounting surface, and bleeder damage during normal international transport. | 0–4 points |
| 14 | Low | Sustainability and responsible sourcing | Ask about recycled material controls, waste treatment, energy management, restricted substances, and supplier audits. | Give additional credit when environmental claims are supported by measurable records or recognized management systems. | 0–4 points |
