Frequently Asked Questions About Peterbilt 388 Brake Parts & Accessories
What years do these brake parts fit for the Peterbilt 388?
Our Peterbilt 388 brake parts are designed to fit model years 2006-2015. However, there can be variations within these years based on specific configurations and build dates. We recommend checking your VIN or contacting our support team with your truck's serial number to ensure exact compatibility. Some brake components, particularly air chambers and slack adjusters, may have mid-year changes that affect fitment.
Are aftermarket brake parts as reliable as OEM for my Peterbilt 388?
Quality aftermarket brake parts from reputable manufacturers like Bendix, Meritor, and Gunite often meet or exceed OEM specifications. These parts undergo the same DOT certification processes and use comparable materials. The main differences typically involve price and availability rather than performance. We carry both OEM and premium aftermarket options, clearly labeled so you can choose based on your needs and budget.
What tools and experience level do I need to install brake chambers or shoes myself?
Installing brake components requires intermediate to advanced mechanical skills and specific tools including a brake spring tool, cage bolt tool, and proper jack stands. Air brake chambers specifically require careful handling due to powerful internal springs. While brake shoes can be replaced by experienced DIY mechanics, we strongly recommend professional installation for air chambers and ABS components to ensure proper adjustment and safety compliance.
How do I know when to replace brake drums versus just the shoes?
Brake drums should be measured for thickness and checked for heat cracks, scoring, or out-of-round conditions. The maximum diameter is stamped on each drum - typically around 16.620 inches for Peterbilt 388 applications. If the drum measures within 0.060 inches of this maximum after machining, or shows blue heat discoloration, deep grooves over 0.080 inches, or any cracks, replacement is necessary. Shoes typically need replacement every 100,000-150,000 miles depending on application.
Do you offer complete brake kit packages for the Peterbilt 388?
Yes, we offer several brake kit options that include matched components for complete axle service. Our standard kits include shoes, hardware springs, and pins. Premium kits add drums and automatic slack adjusters. All kits are configured specifically for Peterbilt 388 axle configurations including 20,000 lb front and 40,000 lb rear applications. Purchasing a complete kit ensures all components work together properly and often provides cost savings over individual parts.
