Brake System Sensor Specification Example for Assembly Programmes: Drilled and Slotted
Brake System Sensor Specification Example for Assembly Programmes: Drilled and Slotted
This is a worked specification for brake system sensor in a drilled and slotted programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The drilled and slotted version exists because the duty cycle on assembly programmes is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a supplier who changed material without saying so.
Example specification
| Item | Brake System Sensor |
|---|---|
| Application | Assembly Programmes |
| Version | Drilled and Slotted |
| Base material | PU Leather |
| Controlled dimensions | 4 key dimensions, recorded per lot |
| Tolerance band | ±0.5 mm |
| Finish | painted |
| MOQ | 3,000 pieces per specification |
| Sampling | 10 working days, 5 days per revision |
| Compliance | SAE J431 |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — PU Leather, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.
Processes involved
- electroplating
- anodising
- assembly line testing
- sintering
- cold forging
- rubber vulcanisation
Where this example applies
Programmes that run drilled and slotted most often specify this build for assembly programmes. Related applications include aftermarket retail, agricultural trailers, rental motorcycles, export programmes, fleet maintenance.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 4.0 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
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.
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
How long does sampling take?
Samples leave the factory in 10 working days, and each revision round adds about 5 days once you have seen the first piece.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 3000 pieces per line.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
