Brake Line Kit for BYD F3: Stainless Steel
This brake line kit for the BYD F3 is specified around stainless steel, which decides how it behaves in service far more than the part name does. We build to a written specification — base material, dimensions, finish and packing — and hold that specification on file so every reorder reproduces the approved piece.
The usual reason a programme changes supplier is not unit price. It is packing that arrived crushed at the port, or lead time that slipped twice before bulk started. Both are specification problems, and both are preventable.

Questions buyers ask
What testing is included?
Standard lots ship with dimensional and hardness reports. SAE J431 documentation is issued with the shipment when your market requires it.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the SAE J431-compliant build instead of a fresh interpretation.
How long does sampling take?
Samples leave the factory in 10 working days, and each revision round adds about 3 days once you have seen the first piece.
How is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
