Don't Get Stuck on the Side of the Road: Essential Brake Checks for Truck Drivers

It’s no secret that a single brake failure on a heavy-duty truck can have devastating consequences, putting your driver and other people at risk. The good news is that by taking preventive maintenance and inspections seriously, you can significantly reduce the risk of brake-related violations and failures.

This guide, brought to you by the brake experts at AM PM Diesel Services, will equip you with essential truck brake checks you can perform to ensure your vehicle operates safely and remains compliant with regulations.

The Power of Pre-Trip Inspections

Federal regulations mandate pre-trip inspections for commercial vehicles, and for good reason. These inspections allow you to identify potential problems with your truck brakes before they escalate into major issues on the road. Regular pre-trip inspections are the cornerstone of preventative truck brake maintenance. Taking 10-15 minutes before each trip to thoroughly check your brakes can prevent breakdowns and costly repairs down the line.

You should focus on these items during your pre-trip inspections:

  • Air System Leaks: Listen for hissing sounds that may indicate air leaks in the air brake system, a crucial component in truck brakes. Leaks can significantly reduce braking power and compromise your ability to stop safely.
  • Low Air Pressure: Check your air pressure gauges to ensure they meet the manufacturer's recommendations. Low air pressure significantly reduces braking performance. In truck air brakes, this can lead to increased stopping distances and even complete brake failure.
  • Visual Inspection of Brake Components: Look for any signs of damage or wear on brake components like drums, shoes, hoses, and slack adjusters. Cracked drums, worn shoes, and loose connections can all impact braking effectiveness.
  • Parking Brake Functionality: Test your parking brake on a level surface to ensure it holds the vehicle securely. A faulty parking brake can be a major safety hazard, especially on inclines.

Don't Neglect Daily Visual Checks

In addition to pre-trip inspections, incorporating daily visual checks into your routine allows you to catch minor issues with your truck brakes before they become major problems. Taking a few minutes each day to visually inspect your brakes is a staple of catching the signs of failing or malfunctioning brakes

Check for any loose connections or visible damage on air chambers, which are crucial components within air brakes in a truck. Damage or leaks in air chambers can compromise braking power.

Also, ensure pushrods and slack adjusters are secure and functioning properly. Problems with these components can affect brake stroke and stopping power. Pushrods connect the brake pedal to the slack adjusters, which maintain proper brake lining positioning.

While pre-trip inspections are comprehensive, daily visual checks allow you to stay on top of minor issues that may arise between trips.

Schedule Weekly and Monthly Inspections

While daily and pre-trip inspections are essential, more thorough weekly and monthly inspections are necessary to maintain optimal truck brake performance. Regular weekly and monthly inspections allow you to delve deeper into the condition of your brakes, identifying potential issues that may not be apparent during cursory checks.

For weekly inspections, focus on inspecting air disc brake rotors for cracks and drum brakes for excessive wear. These components experience significant wear and tear and require close monitoring. Air disc brakes are similar to car brakes, with a disc and caliper design, while drum brakes utilize a rotating drum that presses against brake shoes.

Monthly inspections, on the other hand, should be dedicated to moisture buildup in the air system, as it can lead to corrosion and component failure. Moisture can enter the air system through leaks or condensation, leading to rust and malfunctioning components.

Scheduling regular weekly and monthly inspections ensures a comprehensive approach to truck brake maintenance.

Importance of Pre-Inspection Brake Cleaning

Pre-inspection brake cleaning removes dirt, oil, and debris buildup from components like brake drums, shoes, slack adjusters, and air chambers, allowing for a more thorough and accurate inspection of these components. Clean brakes also improve overall brake performance by preventing contaminants from interfering with proper operation. Contaminants on brake surfaces can reduce friction and lead to longer stopping distances. Clean brakes are essential for safe driving, ensuring optimal braking efficiency during emergency stops and precise maneuvers.

Choosing the Right Brake Cleaner

  • Strong Solvents: Effective brake cleaners should have strong solvents to dissolve grease, grime, and oil buildup effectively. This ensures a cleaner surface for inspection and optimal brake performance.
  • Fast Drying Times: Choose a brake cleaner that dries quickly to minimize downtime during inspections and maintenance procedures. Slow drying times can extend the inspection process and prevent immediate reassembly.
  • Manageable Odors: While some level of odor is inevitable with brake cleaners, opting for a product with a milder odor improves the overall work experience. Strong odors can be unpleasant and potentially harmful if inhaled.

Environmental Responsibility

  • Chlorinated vs. Non-Chlorinated Cleaners: Chlorinated brake cleaners, while less flammable, can pose environmental hazards. These cleaners can harm the ozone layer and pollute waterways if not disposed of properly. Non-chlorinated cleaners are becoming increasingly popular due to their eco-friendly properties.
  • Proper Disposal: It's crucial to dispose of brake cleaner waste responsibly according to local regulations. Brake cleaner typically contains hazardous chemicals that should not be poured down drains or onto the ground. Many automotive parts stores and recycling centers accept used brake cleaner for proper disposal.

Final Words

By following these essential truck brake maintenance checks and incorporating regular maintenance practices, you can ensure your truck's brakes are in top condition. Remember, proper truck brake maintenance is not just about safety; it also minimizes downtime, prevents costly repairs, and keeps your fleet compliant during Department of Transportation (DOT) inspections.
