Pneumatic Brake Specification Example for Rental Motorcycles: Waterproof Version

This is a worked specification for pneumatic brake in a waterproof version 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 waterproof version version exists because the duty cycle on rental motorcycles is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually premature wear on the first batch.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — ABS Plastic, in this example.
  3. List the dimensions that are actually controlled and the tolerance on each.
  4. Name the finish and what it has to survive.
  5. State the inspection level and who pays when a lot fails.

Where this example applies

Programmes that run waterproof version most often specify this build for rental motorcycles. Related applications include dealership service, three-wheelers, city buses, construction equipment, long-haul trucks.

Checks before packing

  • Dimensional report against the approved drawing.
  • AQL 1.5 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 IATF 16949-compliant build instead of a fresh interpretation.

How long does sampling take?

Samples leave the factory in 7 working days, and each revision round adds about 5 days once you have seen the first piece.

Can you match an existing sample?

Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.

What is the minimum order quantity?

The standard MOQ is 500 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.

Send the specification you are working to and we will confirm what we can match, what we would change and why.
