International is recalling 559 2011-2013 Prostar, Durastar, Workstar, and 8600 trucks equipped with piston spring brake feature code 04EVP because an air leak in the parking brake chamber can keep the parking brake from fully releasing.

What's wrong?
The parking brake chamber on 2011-2013 International Prostar, Durastar, Workstar, and 8600 trucks is part of the air brake system. It uses air pressure against a piston and spring to release the parking brake when the truck is ready to move. The system depends on the chamber holding pressure so the brake releases completely.
On affected trucks equipped with piston spring brake feature code 04EVP, the piston bore area of the parking brake chamber can leak air. If the chamber loses air at that point, the piston does not move as designed. The parking brake then stays partly applied instead of fully releasing, leaving the driveline brake dragging after the driver has released it.
There is no warning sign before failure. Once the problem is present, the driver can notice the truck feels held back after the parking brake is released.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
An unreleased parking brake can cause the service brakes to lock up without warning, increasing the risk of a crash. The year and model are not enough. The VIN decides whether this risk applies, so schedule the recall repair soon if your truck is included. Repair will be free at any franchised International dealer once available.
What should I do?
- Check your VIN to confirm your 2011-2013 International Prostar, Durastar, Workstar, or 8600 is included in this recall.
- Contact a franchised International dealer to ask whether the free spring brake chamber replacement is open for your VIN.
- Reference recall number 12V465 when you call, and bring the owner notice if you have it.
- Avoid driving if the parking brake does not fully release or the service brakes lock up. Ask the dealer about towing before moving the truck.
What happens at the repair
At the dealer, an International technician replaces the spring brake chamber tied to the parking brake system. The replacement is listed as free of charge, and the recall began on November 6, 2012. Until the dealer confirms the repair can be performed for your VIN, treat the free spring brake chamber replacement as the repair path once available. Ask the service desk to confirm parts availability before arranging service.
