Frequently Asked Questions About International 9900/i/ix Brake Parts & Acc.
What brake parts are compatible with my specific International 9900 model year?
The International 9900 series (including 9900i and 9900ix models) spans from 1985 to present, with significant brake system changes occurring in 2003 and 2008. For 1985-2002 models, most use standard S-cam drum brakes with 16.5" x 7" shoes. Models from 2003-2007 may have either drum or disc brakes, while 2008+ models predominantly feature air disc brake systems. Always verify your specific VIN and brake configuration before ordering, as International offered multiple brake options within the same model year.
Can I upgrade my drum brakes to disc brakes on my 9900i?
Yes, drum-to-disc conversions are possible but require a complete system replacement including rotors, calipers, brake chambers, and often new wheel hubs. The conversion typically costs between $3,000-$5,000 per axle and requires approximately 8-12 hours of professional installation. Most conversions use Bendix ADB22X or Meritor EX225 disc brake systems. Note that you'll also need to update your truck's ABS module programming to accommodate the disc brake configuration.
How often should I replace brake chambers and slack adjusters on my International 9900?
Brake chambers typically last 300,000-500,000 miles under normal conditions, while automatic slack adjusters should be inspected every 50,000 miles and replaced around 250,000-350,000 miles. Signs of needed replacement include excessive air leakage (more than 3 psi per minute), inconsistent brake adjustment, or visible damage to the diaphragm. For severe-duty applications or mountainous routes, expect to replace these components 30-40% more frequently.
What's the difference between standard and long-stroke brake chambers for the 9900ix?
Standard brake chambers (Type 30) provide 2.5 inches of pushrod travel, while long-stroke chambers (Type 30LS) offer 3.0 inches of travel. Long-stroke chambers provide approximately 20% more braking force and allow for greater brake lining wear before adjustment is needed. Most 2008+ International 9900ix models come factory-equipped with long-stroke chambers. When replacing, ensure all chambers on an axle are the same type to prevent uneven braking.
Which brake lining material works best for different hauling applications?
For general freight and highway use, semi-metallic linings (FF or GG-rated) provide the best balance of stopping power and longevity, typically lasting 150,000-200,000 miles. Heavy-haul and mountain operations benefit from severe-duty metallic linings (HH-rated) that resist fade but wear faster (100,000-150,000 miles). For city delivery with frequent stops, organic linings reduce noise and dust but require replacement every 75,000-100,000 miles. Always match friction ratings across all axles to ensure balanced braking performance.
