Frequently Asked Questions About International 8600 TranStar Drum Brake Parts

What years of International 8600 TranStar are these drum brake parts compatible with?

Our drum brake parts are designed to fit International 8600 TranStar models from 2007 to 2017. However, compatibility can vary based on specific configurations and axle types. We recommend checking your VIN or consulting with our parts specialists to ensure proper fitment, especially for trucks with specialized brake systems or aftermarket modifications.

How do I know when to replace my drum brake shoes versus just adjusting them?

Replace your brake shoes when the lining thickness reaches 1/4 inch or less at the thinnest point, if you notice cracks or heat damage on the lining, or if the shoes are contaminated with oil or grease. Typical replacement intervals range from 100,000 to 250,000 miles depending on driving conditions. If your shoes still have adequate lining (above 1/4 inch) but braking feels weak, adjustment may be all that's needed.

Are aftermarket drum brake parts as reliable as OEM for heavy-duty trucking applications?

Quality aftermarket drum brake parts that meet or exceed FMVSS 121 standards can perform just as well as OEM parts. Look for components made from high-grade steel with proper heat treatment and friction materials rated for your typical loads and routes. Many of our aftermarket options carry DOT certification and come with warranties comparable to OEM parts, often at 30-40% less cost.

What tools and skills are needed to replace drum brake components on an 8600 TranStar?

Drum brake replacement requires a brake spring tool kit, large sockets (typically 3/4" to 1-1/2"), a brake adjustment gauge, and proper jack stands rated for commercial vehicles. The job typically takes 2-3 hours per wheel for experienced mechanics. Critical steps include proper spring tension, correct shoe-to-drum clearance (typically .020-.030"), and proper adjustment of the slack adjusters. We strongly recommend professional installation if you lack commercial vehicle brake experience.

Can I mix different brands of brake shoes and drums, or should I stick with matched sets?

While mixing brands is technically possible if specifications match, we recommend using matched sets from the same manufacturer when replacing both shoes and drums. This ensures consistent friction characteristics, wear patterns, and heat dissipation. If only replacing shoes, ensure the new friction material is compatible with your existing drums' condition and that the arc radius matches properly for full contact.
