What's wrong?
The 2012 Spartan Mg and K2 chassis use an air brake system, which relies on compressed air to apply and release the brakes. The 3030 brake chambers are part of that system. They convert air pressure into mechanical force, so the brakes can hold the chassis when parked and respond when the driver applies the brake pedal.
On the recalled chassis, the brake chamber setup does not meet the required park brake and draw bar performance requirements for air brake systems. That means the concern is not a worn pad or a loose line. The brake system, as built, does not meet the standard it was required to meet for holding and braking performance.
There is no warning sign before failure. Owners should not expect a dashboard light, noise, or change in pedal feel to show that this recall applies.
Who's affected?
Covers both Mg and K2 Spartan models from the 2012 model year, both involving the brake system.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific vehicle.
What's the safety risk?
A parking brake that does not hold can let the vehicle move after it is parked. If the vehicle rolls, injury or property damage can occur without warning. Until the repair is complete, take extra care when parking and avoid relying on the parking brake alone. Repair will be free at any franchised Spartan dealer once available.
What should I do?

- Contact Spartan customer service at 1-517-543-6400 to confirm the brake-chamber repair path for recall number 12V125.
- Ask about the free improved brake-chamber installation that fixes the park-brake holding problem.
- Bring the recall notice if Spartan mailed one. If not, reference recall number 12V125 when you call.
- Avoid relying on the park brake alone until the repair is complete; chock the wheels when parked.
