The finish pass on a brake surface sets the flatness and the texture the pad will see. This clip is that pass, light and fast, on a cast iron disc.
What the clip shows
- Finish turning the friction surface
- Light depth of cut on cast iron
- Surface texture as the insert leaves the face
Why this insert suits the cut
A brake disc that finishes with runout or a poor texture will pulse under braking. The finishing insert has to hold a sharp edge across the full face, including the outer rim where the cut is interrupted.
Where this part is used
Brake NVH complaints often trace back to the finish pass rather than the casting. That is why the finishing insert gets its own attention on the line.
What to send with an inquiry
- Flatness and surface texture specification
- Face width and whether the cut is interrupted
- Insert life target per shift
