Pneumatic Brake Specification Example for Delivery Vans: Adjustable Type
Pneumatic Brake Specification Example for Delivery Vans: Adjustable Type
This is a worked specification for pneumatic brake in a adjustable type 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 adjustable type version exists because the duty cycle on delivery vans is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually packing that arrived crushed at the port.
Example specification
| Item | Pneumatic Brake |
|---|---|
| Application | Delivery Vans |
| Version | Adjustable Type |
| Base material | Forged Aluminium |
| Controlled dimensions | 4 key dimensions, recorded per lot |

| Finish | as machined |
| MOQ | 500 pieces per specification |
| Sampling | 7 working days, 3 days per revision |
| Compliance | REACH |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Forged Aluminium, 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
- CNC machining
- ultrasonic cleaning
- shot blasting
- cold forging
- laser cutting
- assembly line testing
Where this example applies
Programmes that run adjustable type most often specify this build for delivery vans. Related applications include trailer axles, rental motorcycles, agricultural trailers, workshop replacements, passenger cars.
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
What testing is included?
Standard lots ship with dimensional and hardness reports. REACH documentation is issued with the shipment when your market requires it.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 500 pieces per line.
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.
How long does sampling take?
Samples leave the factory in 7 working days, and each revision round adds about 3 days once you have seen the first piece.
Share a sample or a drawing and we will quote against a written specification, not against a photograph.
