What's wrong?
The air brake system on the 2010 Peterbilt 320 uses compressed air, stored in air tanks, to apply and release the truck's service brakes. Those tanks give the brake system a reserve supply so the brakes have enough air available when the driver presses the pedal. On trucks with a Hendrickson HLR2 non-steering pusher axle, that reserve is part of proper brake operation.
These Peterbilt 320 trucks were built without the required number of air tanks for the brake system. With too little air storage, the system does not meet the federal air brake requirement and does not have the setup Peterbilt specified for proper brake operation. The defect is not a worn part from normal use. It is a manufacturing configuration problem tied to how the affected trucks were built.
There is no warning sign before failure. A driver should not rely on a dash light, sound, or change in pedal feel to confirm whether the truck is included.

What's the safety risk?

What should I do?
- Check your VIN to confirm your 2010 Peterbilt 320 is included in this recall.
- Contact a franchised Peterbilt dealer to ask whether the free air-reservoir installation is ready for your truck.
- Reference recall number 10V034 when you call Peterbilt or the dealer.
- Bring the recall notice if you have it, and ask the dealer to install the added air reservoir that supports proper air-brake operation.
- Avoid hauling or operating the truck until Peterbilt confirms the brake-system recall repair is complete.
What happens at the repair
At the dealer, a Peterbilt technician installs an additional air reservoir in the truck's air system. The added reservoir gives the brake system the required air tank capacity described for this recall. The dealer repair will be free once available, with parts and labor covered under the campaign. Ask the service desk to confirm the repair for your VIN before bringing in the truck.
