"A foot valve on a semi-truck commonly referred to as the brake pedal valve or treadle valve is a key component of the air brake system. It is located under the drivers foot pedal and is responsible for controlling air pressure to the service brakes when the brake pedal is pressed. How It Works: 🔹 When the driver presses the brake pedal the foot valve meters air pressure from the supply tanks to the brake chambers engaging the service brakes. 🔹 When the driver releases the pedal the valve vents the air pressure allowing the brakes to release. Common Issues with a Foot Valve: ⚠ Sticky or Slow"

"💥💧 DD15 Fuel Line Leak Watch This Diagnostic Trick 🛠🚛 In this clip our tech is diagnosing a fuel line leak on a Detroit DD15. With the engine running he carefully blows air along the outside of the fuel line connection and you can see fuel spray out from the fitting. This is a real-world in-bay technique to confirm fuel line leaks when: 🔧 Engine is running 🔧 Leaks arent visible until pressure is applied 🔧 No fuel shows at idle but still causes rough run or air intrusion He then checks the next line and no leak is present confirming the issue is isolated. 🧠 On a DD15 air in the fuel"

"🚨 DD15 Low Oil Pressure Dont Tear Into Bearings Before Checking THIS 🛠🛢 This is one of the most common causes of low oil pressure on a DD15. And if its not addressed it can lead to rod and main bearing failure. 🔧 The oil pickup tube O-rings seal the connection between the pump and the suction manifold. After [------] miles they often lose their sealletting air into the system and dropping pressure. We recommend replacing the O-rings and inspecting the manifold for brittleness during any oil pan job. ✅ Inspect/replace at 500K miles ✅ Check suction manifold for cracks ✅ Prevent catastrophic"
