What's wrong?
The foot brake valve on the 2020 Kenworth T270 and T370 is the valve under the brake pedal that starts the air-brake application. When the driver presses the pedal, the treadle valve sends air pressure through the brake system so the service brakes apply. The air supply hose and its compression fitting have to stay tight for that pressure path to work.
On affected trucks, the compression fitting on the brake treadle valve was not tightened enough during assembly. That loose fitting lets the air supply hose separate from the valve. Once the hose comes off, the valve no longer receives the air supply it needs to command normal braking.
There is no warning sign before failure. A driver can press the brake pedal and find that the service brakes do not respond normally, so the truck needs dealer inspection and repair before it is put back into service.

What's the safety risk?
This recall concerns brake treadle valve hose connections that leave the vehicle with reduced braking ability if a hose separates, increasing crash risk. Schedule the dealer inspection soon, and use extra following distance until the dealer confirms the fittings are tight. Repair is free at any franchised Kenworth dealer.
What should I do?
- Check your VIN to confirm your 2020 Kenworth T270 or T370 is included in this recall.
- Contact a franchised Kenworth dealer to schedule the free brake treadle valve hose inspection and fitting tightening for the loose fittings that can let the air supply hose separate.
- Bring the recall notice if Kenworth mailed one. If not, reference recall number 19V606 when you call.
- Drive cautiously until the inspection and any needed tightening are complete, since a separated air supply hose reduces braking ability.
What happens at the repair
At the dealer, a Kenworth technician inspects the brake treadle valve hose connections for loose compression fittings. If a fitting is loose, the technician tightens it so the air supply hose stays secured to the valve. The inspection and any needed tightening are free under recall 19V606. Parts and labor are covered, and the dealer can confirm whether your T270 or T370 is included by VIN.
