Frequently Asked Questions About Peterbilt 359 Brake Parts & Acc.
Will these brake parts fit my specific year Peterbilt 359?
Most of our Peterbilt 359 brake parts are designed to fit models from 1967 to 1987, which covers the entire production run. However, there were minor changes between early models (1967-1985) and late models (1986-1987), particularly in brake chamber sizes and air line fittings. Always check the product description for specific year compatibility, or contact our technical support team with your OEM number for exact fitment verification.
What's the difference between standard and heavy-duty brake shoes, and which do I need?
Standard brake shoes typically feature 4720 or 4515 friction material and work well for highway and light-duty applications. Heavy-duty shoes use 4709 or 4707 friction material, offering better heat resistance and longer life for vocational trucks, heavy hauling, or mountain driving. If your 359 regularly carries loads over 70,000 lbs GVW or operates in severe service conditions, heavy-duty shoes are recommended. Check your current shoes for the friction code stamped on the lining edge.
Can I install these brake components myself, or do I need special tools?
Basic brake shoe replacement requires standard hand tools, a brake spring tool, and jack stands. However, brake chambers, slack adjusters, and S-cam bushings often require specialized tools like a cage bolt wrench, S-cam bushing driver, and proper torque specifications. Air system components must be properly sealed and tested. While experienced mechanics can handle most jobs, we recommend professional installation for DOT compliance and safety, especially for air brake components.
How do I know when to replace S-cam bushings and brake hardware?
Replace S-cam bushings when you notice excessive play in the S-cam shaft (more than 0.030" radial movement), uneven brake shoe wear, or during every second brake shoe replacement. Hardware kits including springs, pins, and clips should be replaced with every brake job to ensure proper shoe return and prevent dragging. Worn hardware is a leading cause of premature brake wear and can increase stopping distances.
Are aftermarket brake parts as reliable as OEM for my Peterbilt 359?
Quality aftermarket brake parts from reputable manufacturers like Bendix, Meritor, and Gunite often meet or exceed OEM specifications. These parts undergo the same FMVSS 121 testing and carry DOT certification. The key is choosing parts from established brands rather than generic imports. Our brake parts come from trusted suppliers and include proper documentation for DOT inspections. Many fleet operators actually prefer certain aftermarket options for their improved friction formulas and longevity.
