A brake must clear the ski and belong to the exact binding. Match it to the ski’s waist width, then have the shop confirm that the arms deploy and retract correctly on the mounted equipment.
Use width as a first filter
Tyrolia’s selection guidance recommends a brake at least as wide as the ski and no more than 15 mm wider. For a 90 mm waist, that gives a preliminary 90–105 mm range under that manufacturer’s guidance. It is not proof that every brake in that range fits every binding.
| Check | Why it matters |
|---|---|
| Ski waist in millimetres | Sets the width comparison; tip width and ski length do not. |
| Binding model and brake part | Interfaces and replacement parts are model-specific. |
| Mounted clearance | The arms must clear the ski’s sides and function through the full movement. |
What to bring to the shop
- The exact ski and binding model, waist width and boot—not just a product family name.
- A photo or part number if buying a replacement brake.
- The binding manufacturer’s compatible brake options. If none fits, resolve the equipment choice rather than improvising a bent brake.
An excessively wide brake can protrude beyond the ski. A narrow one can fail to clear it. The final decision includes mounting and function, not just matching numbers on a web listing.
