Owners of the 2017 Peterbilt 367 truck have reported issues with the brake systems of both the truck and trailer, particularly concerning mismatched brake discs and drums. This article will explore the common causes of these brake issues and provide troubleshooting methods and solutions to help owners identify and resolve brake system failures.
Common Symptoms of Brake Issues
Users have reported various issues with the brake system, including uneven friction between the brake discs and drums, leading to poor braking performance. In some cases, the brakes may not function properly, causing instability during braking. This problem is especially noticeable when the truck and trailer are connected, as the brake system fails to operate synchronously, affecting overall braking performance. Some owners have also noted excessive wear and unusual noises in the braking components during operation.
Causes of Brake Issues
The brake issues on the 2017 Peterbilt 367 truck and trailer are primarily caused by mismatched brake discs and drums, worn components, contaminated brake fluid, and air in the brake system. By regularly inspecting the brake system, replacing worn components, and maintaining proper fluid levels, owners can effectively avoid these issues and ensure the safety and reliability of their vehicles. Keeping the brake system in good condition will significantly improve overall performance and safety.

Causes of Brake Issues
- Mismatched Brake Discs and Drums
A common cause of poor braking performance is the mismatch between the brake discs and drums in the truck and trailer. The size or design incompatibility of these components can lead to insufficient or uneven friction, which negatively impacts the effectiveness of the braking system.
- Worn Brake Components
Over time, brake discs, drums, pads, and other components wear down, especially in high-intensity working conditions. Excessive wear on these parts can lead to brake failure or imbalance, which compromises the safety and performance of the vehicle.
- Low or Contaminated Brake Fluid
Brake fluid plays a crucial role in the operation of the braking system. Low levels or contamination of brake fluid can result in a sluggish brake response or even brake failure in extreme cases.
- Air in the Brake System
Air trapped in the brake system can reduce brake pressure and hinder the system's ability to function properly. This is often caused by improper brake fluid replacement or poor sealing within the brake system.
- Check for Compatibility Between Brake Discs and Drums
Ensure that the brake discs and drums on both the truck and trailer match the manufacturer's specifications. If any mismatched components are found, replace them with properly sized and designed parts to restore proper braking function.
- Inspect and Replace Worn Brake Components
Regularly inspect brake pads, discs, and drums for wear. If components show signs of excessive wear or damage, replace them immediately. Regular maintenance and inspection can help prevent brake issues related to worn-out components.
- Check Brake Fluid Levels and Quality
Verify that the brake fluid is at the proper level and free from contamination. If the brake fluid is low or contaminated, replace it with fresh, high-quality fluid. Ensure the brake system is sealed properly to avoid air infiltration.
- Bleed the Brake System to Remove Air
When replacing brake fluid, make sure to properly bleed the brake system to remove any trapped air. If air is found in the brake system, perform the necessary steps to expel it and restore proper brake pressure.
- Regular Brake System Inspections
Perform regular inspections of the truck and trailer's brake system, including discs, drums, pads, and fluid levels. Timely identification and replacement of worn-out components can prevent brake failure and improve safety.
- Use High-Quality Brake Parts
Choose high-quality, OEM-approved brake parts to ensure the efficiency and reliability of the braking system. Avoid using incompatible or low-quality components, as they can compromise brake performance and increase the risk of failure.
- Maintain Clean and Proper Brake Fluid Levels
Regularly check brake fluid levels and ensure the fluid is free from contamination. Keep the brake system sealed and monitor the fluid condition to ensure optimal braking performance.
