What's wrong?
The rear brake pads on 2022 Zero Sr, Sr/F, and Sr/S motorcycles are friction pads that press against the rear brake rotor when you use the brake. That pressure helps slow the rear wheel and stabilize the motorcycle during braking. Zero certified these models with a specific rear pad set for the motorcycle brake system standard.
On affected motorcycles, the wrong rear brake pads were installed during production. Zero says operations personnel put SDS platform pads on the manufacturing line for the SR, Sr/F, and Sr/S models, so the motorcycles were correctly assembled with parts that did not match the current regulatory filing. The incorrect pads have silver backing; the correct pads have copper backing.
There is no warning sign before failure. Zero's launch-plan motorcycles were ridden more than 500 miles, and the test riders did not notice a difference in brake performance.
Who's affected?
Covers three 2022 Zero models, all using the same rear brake pad set in the hydraulic brake system.

What's the safety risk?
Incorrect rear brake pads can reduce braking performance and increase the risk of a crash. Reduced rear braking can leave you with less stopping support, so schedule the recall repair soon and use extra care until it is done. Repair is free at any franchised Zero dealer.
What should I do?

- Contact a franchised Zero dealer to schedule the free rear-brake-pad inspection and replacement that fixes the incorrect pads.
- Bring the recall notice if Zero mailed one. If not, reference recall number 21V940 when you call.
- Ride cautiously until the rear brake pads are inspected and replaced. Leave extra following distance and avoid hard braking.

What happens at the repair
At the dealer, a Zero technician inspects the rear brake pads and replaces the pads covered by the recall. The replacement parts and labor are free. Zero says there is no separate reimbursement plan because all affected motorcycles are under warranty and no owner was expected to pay for this repair out of pocket. If you already have repair paperwork, ask the service desk how the existing warranty coverage applies.
