Diesel Truck Brake Problems and How to Avoid Them

Diesel truck drivers and fleet managers routinely prioritize tires, engine performance and fluid and oil changes because these systems are essential to vehicle reliability and performance. However, brake maintenance is too often overlooked. Neglecting this critical system can lead to safety concerns, premature wear and costly repairs that could have been prevented with proper maintenance.

Following a handful of preventive maintenance tips can be the difference between business as usual and landing in the shop.

The Progression to Failure

Diesel truck brake components almost always wear slowly, which means issues develop so gradually that they go unnoticed until it’s too late. Heat and friction are the norm under heavy loads, so over time brake pads wear out, rotors become damaged and brake drums and air brake components corrode and eventually fail.

Any of these issues on their own are relatively simple fixes when caught early. The problem is that if they go unnoticed for a long time, that simple fix can become a major repair, meaning more downtime and more money in parts and labor.

Warning Signs

If you want to save time, money and significantly reduce diesel truck-related stress, be on the lookout for common red flags that something is amiss with your brakes:

• Unusual Sounds
  A grinding noise might mean that your brake pads are so worn out that your rotor is now under attack. But before it gets that bad, you should notice squeaks or squeals coming from your wheels. This is the first sign that your brake pads need to be replaced.
• Different “Feels”
  If you’ve been a lot of miles on your diesel truck, you’ve become accustomed to its feel on the road. If you’re noticing a soft or spongy feeling as you apply pressure on your brake pedal, this could be a sign that you’ve got air in your brake lines. It could also mean that your brake fluid is low.
• Vibration
  That alarming shudder or vibration you feel when braking could be caused by warped rotors.
• Dashboard Lights
  Your sensors can spot problems before you hear or feel them. If your dashboard brake light warning is illuminated, don’t ignore it. Get your diesel truck to the shop as soon as possible.

Any of these signs call for immediate action. Getting on it now can save you significant time and money later.

When to Consult With a Professional

Your diligence with brake system health is crucial, but your truck will also need professional attention. Check your truck’s recommended factory maintenance schedule, which is often based on the number of miles you have on your truck.
