Machining (CNC Milling)
Once the raw caliper body is formed, it undergoes precision machining on Computer Numerical Control (CNC) machines. This critical stage involves:
- Rough Machining: Removing excess material to get closer to the final shape.
- Fine Machining: Creating precise dimensions for piston bores, mounting points, fluid passages, and pad recesses. Tolerances are extremely tight to ensure optimal performance and fit.

Assembly
With the caliper body prepared, the internal components are carefully assembled:
- Piston Installation: Pistons, typically made from aluminum or phenolic materials, are inserted into their bores.
- Seal and Boot Installation: High-temperature resistant seals and dust boots are fitted to prevent fluid leaks and protect the pistons from contaminants.
- Bleeder Screw and Banjo Bolt Installation: The bleeder screw allows for air removal from the brake system, and the banjo bolt connects the brake line.

Quality Control and Testing
Throughout the entire process, rigorous quality control checks are performed. The final assembled caliper undergoes:
- Leak Testing: Pressurized fluid is used to detect any leaks from the seals or body.
- Dimensional Inspection: Verifying all critical dimensions against specifications.
- Visual Inspection: Checking for any cosmetic defects or imperfections.
- Functional Testing: Simulating operational conditions to ensure proper piston movement and overall integrity.
