How do I know which brake part fits my Cat motor grader?
Start with your grader model, then match the part number on your old brake component to 2D9600, 3D2219, or 5T7161. Fitment can depend on the model and serial number, so matching the part number is the most reliable way to get the right part. If the number is worn off or you are unsure, our parts team can help confirm fitment.
