Frequently Asked Questions About International 9200/9400 Drum Brake Parts

What years and models are these drum brake parts compatible with?

These drum brake parts are designed specifically for International 9200 and 9400 series trucks manufactured from 1990 through 2003. The 9200 models include both the 9200i and 9200 SBA variants, while the 9400 series covers the 9400i and 9400i Eagle models. Always verify your truck's VIN and brake specifications before ordering, as some mid-year production changes may affect compatibility.

How do I know if I need 16.5" x 7" or 16.5" x 8.625" brake shoes?

The brake shoe size depends on your truck's axle rating and configuration. Generally, trucks with standard 20,000-23,000 lb front axles use 16.5" x 7" shoes, while heavier-duty applications with 12,000-14,600 lb front axles may require 16.5" x 8.625" shoes. Check the stamping on your current brake shoes or consult your truck's build sheet. When in doubt, measure the width of your existing shoes from edge to edge at the widest point.

Can I replace drum brake components myself, or do I need special tools?

While drum brake replacement is possible for experienced DIY mechanics, it requires specific tools including brake spring pliers, brake shoe hold-down spring tools, and a brake drum puller. You'll also need proper jack stands rated for commercial vehicles. The job typically takes 3-4 hours per axle for experienced technicians. Many customers choose professional installation due to safety concerns and the need for proper adjustment of slack adjusters and brake chamber stroke.

What's the difference between standard and severe-duty brake linings?

Standard brake linings work well for highway and moderate-use applications, offering good stopping power and typical wear life of 100,000-150,000 miles. Severe-duty linings contain heat-resistant compounds designed for frequent stopping, mountain driving, or heavy hauling, lasting 150,000-250,000 miles under normal conditions. Severe-duty options cost about 20-30% more but provide better fade resistance and longer service life in demanding applications.

Should I replace drums when changing brake shoes, and how do I check drum condition?

Drums don't always need replacement with shoes, but inspection is critical. Measure the drum's inside diameter - if it exceeds the maximum diameter stamped on the drum (typically 0.120" over original), replacement is required. Look for heat checking, cracks, or deep scoring. Light scoring under 0.015" deep can often be machined out. As a rule of thumb, if you're on your second or third shoe replacement on original drums, it's cost-effective to replace drums to ensure proper brake performance and avoid comebacks.
