Frequently Asked Questions About International RH Drum Brake Parts

Will these drum brake parts fit my specific International truck model and year?

Our International RH (right-hand) drum brake parts are designed to fit most International truck models from 1990 onwards, including ProStar, LoneStar, 9900i, and 9200i series. However, compatibility can vary based on your truck's axle configuration and brake size (typically 16.5" x 7" or 16.5" x 8.625"). We recommend checking your existing brake assembly's part numbers or contacting our support team with your VIN for exact fitment verification.

What's the difference between OEM and aftermarket brake shoes, and which should I choose?

OEM brake shoes meet International's original specifications and typically last 150,000-200,000 miles under normal conditions. Aftermarket options vary in quality - premium aftermarket shoes often match OEM performance at 20-30% less cost, while economy options may wear faster but work well for lighter-duty applications. For heavy-haul or frequent mountain driving, we recommend OEM or premium aftermarket shoes with higher temperature ratings.

Do I need special tools to install these brake components myself?

Yes, proper installation requires specific tools including a brake spring tool, brake shoe retainer tool, and a drum puller. You'll also need a way to properly adjust the slack adjusters and measure shoe-to-drum clearance (typically 0.020-0.030 inches). Many customers find that having a brake shoe gauge and dial indicator helps ensure proper adjustment. If you lack these specialized tools, professional installation is recommended to ensure safety and proper function.

How do I know when my drum brake components need replacement?

Key indicators include brake shoes worn below 1/4 inch thickness, scored or heat-checked drums exceeding maximum diameter specifications (usually stamped on the drum), excessive brake adjustment frequency, or uneven wear patterns. Additionally, any contamination from oil or grease, visible cracks in shoes or drums, or brake fade during normal operation requires immediate attention. Regular 90-day inspections help catch issues early.

Can I mix different brands of brake components, or should I replace everything as a set?

While you can technically mix brands, we strongly recommend replacing components in axle sets (both wheels on the same axle) with matching parts for balanced braking performance. This is especially important for brake shoes and drums. Hardware kits, springs, and pins should always be replaced during brake service regardless of apparent condition, as these low-cost items are critical for proper operation and can cause premature wear if reused.
