What's wrong?
The front brake caliper on the 2022 Zero Sr and Sr/F clamps the brake pads onto the front brake disc when you squeeze the brake lever. It is held to the front fork by mounting bolts, and those bolts have to match the fork threads so the caliper stays tight under braking load.
On affected motorcycles, the wrong caliper bolt was placed on the production line with the correct bolt. The wrong bolt was longer and had coarser threads than the fork was built to accept. When installed, it damaged the threads inside the fork, which allowed the caliper mounting point to lose its grip.
If the caliper starts to loosen, you can hear rattling or knocking during braking. That noise is the warning sign before reduced braking force.

What's the safety risk?
A loose front brake caliper can reduce braking force and increase the risk of a crash. Listen for rattling or knocking during braking, and treat that noise as a reason to slow down and arrange service soon. Repair is free at any franchised Zero dealer.
What should I do?
- Check your VIN to confirm your 2022 Zero Sr or Sr/F motorcycle is included in this recall.
- Contact a franchised Zero dealer to schedule the free front brake caliper bolt and fork inspection, which fixes the loose-caliper risk from incorrect bolts.
- Bring the owner letter if you have it, and reference recall number 22V403 when you call.
- Avoid hard braking and leave extra following distance until the dealer completes the repair.
What happens at the repair
At the dealer, a Zero technician inspects the front brake caliper bolts and fork mounting area. If the wrong bolts damaged the mounting threads or the hardware is incorrect, the technician replaces the front brake caliper bolts and forks as needed. The recall repair is free, including parts and labor. Out-of-pocket repairs already paid are handled through the existing warranty, not through a separate reimbursement program, because the affected motorcycles are under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
