At Brakecrafters, we strive to provide the most accurate fitment information in the industry. However, because much of our catalog covers vintage machinery—often relying on data that is 30 to 60 years old—it is impossible to guarantee 100% accuracy in every instance.
Please review the following terms regarding your purchase:
Our Commitment to Accuracy
- Data Integrity: We continuously update our database to ensure our listings reflect the best available information.
- Continuous Improvement: When a fitment error is identified, we don't just fix the order; we update our master records immediately to prevent the error from recurring for others.
- The "Make It Right" Guarantee: If you receive a part that does not fit your specific year, make, or model despite our listing, we are committed to resolving the issue and ensuring you get what you need for a successful repair.
How You Can Help
In the rare event of a discrepancy, we may ask for your assistance. This might include providing:
- Photos of the original part alongside the new part.
- Casting numbers or specific measurements from your master cylinder or calipers. Use Millimeters for better Accuracy.
- VIN or Production Date information is not actually helpful to us; we are not a brand dealer.
Your feedback is a vital part of maintaining the integrity of the vintage motorcycle community's technical data. By working together, we can keep these classic machines on the road safely.
Note: Always verify your specific components before beginning installation. If something looks different than the OEM part you removed, please contact us before proceeding with the rebuild.
