What's wrong?
The air disc brake on 2011-2013 International Workstar, Transtar, Prostar, and Durastar trucks uses compressed air to apply the brake caliper. The caliper is the clamping part that squeezes the brake pads against the rotor, and it has to stay firmly attached to its mounting plate for the truck to brake straight and predictably.
The defect involves bolts that fasten the caliper to that mounting plate. On affected trucks, those bolts were not tightened to the specified torque, meaning they were not tightened to the required clamping force. If the bolts loosen, the caliper can separate from the mounting plate during a braking application, causing the truck to pull unexpectedly or need more distance to stop.
There is no warning sign before failure. If the truck pulls during braking or takes longer to stop, treat that as a brake problem that is already happening and keep the vehicle out of service until it is inspected.
Who's affected?
Covers four International truck models across the 2011, 2012, and 2013 model years, all tied to the brake system.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
During braking, the truck can pull unexpectedly or take longer to stop, increasing the risk of a crash with property damage, personal injury, or death. If braking feels uneven, stop in a safe place and contact an International dealer for recall guidance. Repair will be free at any franchised International dealer once available.
What should I do?
- Check your VIN to confirm your 2011-2013 International Workstar, Transtar, Prostar, or Durastar is included in this recall.
- Review any owner notice from International before you call the dealer.
- Contact a franchised International dealer and ask about the free air-disc-brake caliper-bolt repair for recall number 12V403.
- Bring the recall notice if you have it, and tell the dealer the brake caliper mounting bolts can loosen or separate.
- Drive cautiously until the repair is complete. Leave extra following distance and avoid hard braking.
What happens at the repair
At the dealer, an International technician checks the Bendix air disc brake caliper mounting bolts. The technician installs missing caliper mounting bolts and tightens the caliper mounting bolts to the specified torque so the caliper stays secured to the mounting plate. The dealer repair will be free once available, with parts and labor covered under the recall. If the truck has braking pull or a longer stopping distance before the repair opens, call an International dealer and ask how they want the vehicle moved for service.

Frequently asked questions
What is recall 12V403?
Recall 12V403 covers 956 2011-2013 International Workstar, Transtar, Prostar, and Durastar vehicles with Bendix air disc brakes. The caliper mounting bolts were not tightened to the specified torque, which can let the caliper separate and increase crash risk. International dealers will replace missing bolts and tighten the bolts for free.
What should I do if my 2011-2013 International Workstar, Transtar, Prostar, or Durastar is on this recall?
Check your VIN to confirm your specific vehicle is included in recall 12V403. If it is, contact a franchised International dealer to schedule the brake caliper bolt inspection and repair. Reference recall number 12V403 when you call. The repair is free.
Is the recall repair free?
Yes. Federal recall law requires manufacturers to perform recall repairs at no cost, and International dealers will replace missing caliper mounting bolts and tighten the caliper mounting bolts free of charge.
What is the safety risk?
The safety risk is reduced braking control. Loose caliper mounting bolts can let the air disc brake caliper separate from the mounting plate, causing an unexpected pull while braking or longer stopping distance. That increases crash risk, including property damage, personal injury, or death.
What if I bought this International truck used?
The free recall repair still applies. Federal recall law covers the vehicle, not the first owner. Check your VIN to confirm whether your specific truck is included, then contact a franchised International dealer and reference recall number 12V403 when scheduling service.
