Not a parts counter
Nothing on this page is an offer of finished parts from stock. Output belongs to the programme that ordered it; there is no availability list, no exchange pool and no published part count.
Part family 05 · Brake and wheel
Steel brake and wheel components, built to your requirements
Rotor discs, friction pads, disc cores and the accessories that go with them. Each item is produced to the drawing, the acceptance criteria and the delivery shape you define — as an individual part or as a kit shipping with the rest of the brake work.
What is in scope
Five groups. If an item sits next to them in the assembly but is not on your drawing, it is raised as a scope question rather than quietly added.
| Item | Where it sits | Who defines it | Records shipped |
|---|---|---|---|
| Rotor discs | Moving discs in a steel brake stack | Your drawing sets the geometry, material, surface condition and the interfaces with the torque tube | Dimensional record, material certificate with heat and lot, surface treatment record |
| Friction pads and linings | Friction elements fitted to the stack or carrier | Material, bonding or attachment method, and the acceptance criteria are all defined by you | Material and lot traceability, bond or attachment record where the drawing calls for it |
| Disc cores and backing structures | The structural part of a disc or pad assembly | Section, flatness and interface control come from your design data, not from a standard pattern | Dimensional report against the ballooned drawing, first article report where required |
| Brake accessories | Small components and hardware used around the brake assembly | Each item is quoted to its own drawing revision and grouped into the same shipment as the discs | Certificate of conformity, lot traceability, packing list keyed to your order |
| Wheel accessories | Related hardware supplied alongside the brake work | Scope is written into the programme so that nothing arrives as an unplanned extra | Material certificates and the same traveller discipline as the disc items |
Carbon heat sink discs are a separate family with its own handover stages — seecarbon brake discs. The two families share the same rule: the holder defines the part, the records and the release.
What “to your requirements” actually commits us to
Four decisions that stay on your side of the table, written down so a quotation cannot quietly move them.
| Decision | What it means in practice |
|---|---|
| The drawing is yours | Geometry, material, finish, marking and revision state come from your data. We do not substitute a standard part that happens to look similar. |
| The acceptance criteria are yours | Inspection characteristics, test evidence and the concession route are agreed before the first article, so there is no argument at receiving inspection. |
| The delivery shape is yours | First article, pilot batch or repeat production, packed as individual items or as a kit — the order defines it, and the paperwork follows that definition. |
| The release stays with you | Output is produced against your programme and released under your approval. We provide the records that support that signature. |
Three boundaries
The same three that apply to the cabin interior families. A second part family does not loosen any of them.
No unnamed substitutions
Friction material formulations, bonding agents and process settings are defined by your specification and by the qualified facility’s technical agreement. They are not published, and they are never changed without a written instruction from you.
No plant of our own
Manufacturing is carried out at qualified partner facilities in China. We own the routing, the programme management and the record discipline; the certificates are in the facility’s name and are available for your audit.
What you send, what comes back
With these four items the reply is a routing and a first article plan. Without them it is only a range.
From you
- Drawing and revision for each item, or a sample with an engineering brief if no drawing exists yet
- Material, finish, marking and acceptance requirements
- The approval the output will be released under, plus the State of Registry you sell into
- First order quantity and expected annual volume, stated separately
From us
- Parts to the revision actually issued, packed to the agreed delivery shape
- Certificate of conformity and, where the programme requires it, an AS9102 first article report
- Material certificates, heat and lot traceability, process traveller signed at each operation
- A written release path determination before the first production order is placed
Send the drawing status for one brake item
A released drawing, a draft, or a sample with no drawing at all — each one leads to a different first step, and we will name which one applies before anything is quoted.
