Case Study: Brake Fluid Reservoir Supply for an agricultural cooperative in Latin America

Brake Fluid Reservoir for An agricultural cooperative in Latin America

An agricultural cooperative came to us with a brake fluid reservoir programme for Latin America. The brief was ordinary and unforgiving at the same time: a fixed launch window, a landed cost that had to survive freight and duty, and a part that had to match an existing sample. This case records what was specified, what went wrong in sampling and how the bulk order landed.

The starting point

  • A specification nobody had written down
  • Lead time that slipped twice before bulk started
  • Packing that arrived crushed at the port

What was specified

PartBrake Fluid Reservoir
ClientAn agricultural cooperative
MarketLatin America
Volume50,000 pieces across 2 specifications
Base materialTempered Glass
Sampling rounds4
Delivery window8 weeks from PO to ex-factory
ComplianceISO/TS 16949

How it was resolved

  1. The specification was rebuilt around Tempered Glass and the tolerance locked before bulk.
  2. A pre-production sample was approved and kept as the golden reference.
  3. Production ran with in-line inspection and a mid-run photo report.
  4. Cartons were packed to the client's own barcode and ratio specification.
  5. Documentation shipped with the goods instead of after them.

Result

  • 50,000 pieces delivered inside the 8-week window.
  • Unit cost held within 1.5% of the original quotation.
  • Inspection-related rejection stayed under 1.5%.
  • The specification is on file, so reorders reproduce the approved sample.

What we would repeat

Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
