Hydraulic Brake Specification Example for Aftermarket Retail: Folding Type
Hydraulic Brake Specification Example for Aftermarket Retail: Folding Type
This is a worked specification for hydraulic brake in a folding 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 folding type version exists because the duty cycle on aftermarket retail 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 | Hydraulic Brake |
|---|---|
| Application | Aftermarket Retail |
| Version | Folding Type |
| Base material | Powder Coated Steel |
| Controlled dimensions | 4 key dimensions, recorded per lot |
| Tolerance band | ±0.05 mm |
| Finish | zinc plated |
| MOQ | 1,000 pieces per specification |
| Sampling | 10 working days, 3 days per revision |
| Compliance | TUV |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Powder Coated Steel, 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
- powder coating
- gravity casting
- precision stamping
- CNC machining
- shot blasting
- anodising
Where this example applies
Programmes that run folding type most often specify this build for aftermarket retail. Related applications include aftermarket retail, off-road bikes, delivery vans, fleet maintenance, passenger cars.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 2.5 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
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.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 1000 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.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the TUV-compliant build instead of a fresh interpretation.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
