Review brake bosses, mounting axles and frame interfaces from the actual caliper, fork and frame drawings.
Brake bosses and mounting axle references.
Compare existing front, rear and stepped-boss configurations. Final geometry is selected against the frame and brake interface drawing.
PS-B02
Rear post-mount axle
Rear-frame mounting reference for the defined brake interface.

PS-B04
Brake boss configuration
An additional boss geometry for frame and fork project review.

PS-B03 dimension reference. Mounting geometry and production tolerances remain project-specific.
Keep the mounting geometry in view.
Review the brake hardware with its mating faces and assembly context, from the mounting datum to the installed fastener.
Mounting faces
Identify contact surfaces, datums and the positional relationship to the frame or fork.
Threaded features
Define thread specification, engagement, shoulder geometry and the required installation access.
Caliper & rotor context
Provide the brake-interface drawing and relevant caliper and rotor information for the intended assembly.
Finish & joining
Include coating allowance and the specified frame attachment or joining process where relevant.
Details to align as the project develops.
Start with the available drawing and quantity. Add the material, assembly and inspection details as they are defined.
Review material optionsPost mount, flat mount or custom interface
Identify the intended interface and provide its controlling drawing. Do not select a configuration from its name or appearance alone.
Dimensions, assembly and tightening
Use the customer drawing and applicable brake-manufacturer assembly instructions to define tolerances, installation and tightening criteria for the joint.
Inspection, finish and quotation inputs
Identify critical geometry, finish requirements, initial quantity and required inspection records. Include any environmental or corrosion requirement as a project specification.
Start with the files you have.
Send a drawing, sample reference or BOM with the quantity and application. Open details can be discussed during the project review.
Part or assembly information
2D drawing, STEP file, BOM, or physical sample information.
Quantity and project stage
Prototype, first production order or repeat requirement.
