Brake Fluid Reservoir for An agricultural cooperative in Southern Africa

An agricultural cooperative came to us with a brake fluid reservoir programme for Southern Africa. 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 supplier who changed material without saying so
  • Packing that arrived crushed at the port
  • A specification nobody had written down

What was specified

PartBrake Fluid Reservoir
ClientAn agricultural cooperative
MarketSouthern Africa
Volume50,000 pieces across 4 specifications
Base materialKevlar Composite
Sampling rounds4
Delivery window4 weeks from PO to ex-factory
ComplianceSAE J431

How it was resolved

  1. The specification was rebuilt around Kevlar Composite 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 4-week window.
  • Unit cost held within 3.0% of the original quotation.
  • Inspection-related rejection stayed under 0.5%.
  • The specification is on file, so reorders reproduce the approved sample.

What we would repeat

Approve a pre-production sample made from the actual bulk material. Substitute material behaves differently in service.

Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
