Frequently Asked Questions About International ProStar Drum Brake Parts

Will these drum brake parts fit my specific ProStar model year?

Our International ProStar drum brake parts are designed to fit ProStar models from 2008 through 2017. However, there can be variations based on your specific axle configuration and brake size. We recommend checking your existing brake drum diameter (typically 16.5" x 7") and confirming your axle manufacturer (Meritor, Dana, or Hendrickson) before ordering. If you're unsure, contact us with your VIN and we'll help verify the correct parts for your truck.

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

Standard drum brake shoes are suitable for typical highway driving and moderate loads. Severe-duty shoes feature thicker friction material (typically 0.75" vs 0.625"), higher temperature resistance, and reinforced backing plates. If you regularly haul maximum loads, drive in mountainous terrain, or make frequent stops, severe-duty shoes will provide 20-30% longer service life. The initial cost is about 15-20% higher, but the extended lifespan often makes them more economical for heavy-use applications.

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

While drum brake replacement is possible for experienced mechanics, it requires specific tools including a brake spring tool set, drum puller, and proper jack stands rated for commercial vehicles. The job typically takes 3-4 hours per axle for someone familiar with the process. Critical steps include proper spring tension adjustment and brake shoe arc grinding for optimal contact. Many customers choose professional installation to ensure DOT compliance and proper adjustment, which typically costs $300-500 per axle at most truck service centers.

How do I know when my ProStar drum brakes need replacement?

Key indicators include brake shoes worn to 1/4" thickness or less, scoring or heat cracks on drum surface exceeding 0.060" deep, or drums worn beyond maximum diameter (usually stamped on the drum edge). Also watch for increased stopping distance, brake fade, or unusual noises during braking. ProStar drums typically last 250,000-350,000 miles with proper maintenance, while shoes usually need replacement every 100,000-150,000 miles depending on driving conditions and load weights.

Are aftermarket drum brake parts as reliable as OEM for my ProStar?

Quality aftermarket drum brake components from established manufacturers like Gunite, Webb, and Accuride meet or exceed OEM specifications and often carry equal or better warranties. These parts use the same friction formulations and manufacturing standards as original equipment. The main difference is price - aftermarket parts typically cost 25-40% less than OEM. Always verify that parts meet FMVSS 121 standards and check that hardware kits include all necessary springs, pins, and adjusters specific to your ProStar's brake system.
