Frequently Asked Questions About International 9300/9370 Brake Chambers & Acc.

Will these brake chambers fit my specific International 9300 or 9370 model year?

Most brake chambers for International 9300/9370 trucks are compatible with models from 1987 through 2007. However, there can be variations based on your truck's brake system configuration (standard vs. long stroke) and whether you have disc or drum brakes. Always verify the chamber size (Type 20, 24, or 30) and stroke length before ordering. Check your existing chamber's data tag or consult your truck's build sheet for exact specifications.

What's the difference between standard and long stroke brake chambers, and which do I need?

Standard stroke chambers typically have a 2.5" stroke, while long stroke chambers have a 3" stroke. Long stroke chambers are required on trucks manufactured after specific dates due to FMVSS regulations. For International 9300/9370 trucks built after 1994, you likely need long stroke chambers. You can identify your current type by checking the data tag on your existing chamber or measuring the pushrod travel when brakes are fully applied.

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

While brake chamber replacement is possible for experienced mechanics, it requires specific safety precautions and tools. You'll need a caging bolt tool, proper jack stands, and air system knowledge. The chambers contain powerful springs that can cause serious injury if mishandled. Most customers report needing 1-2 hours per chamber. If you're not experienced with air brake systems, professional installation is strongly recommended for safety reasons.

Are aftermarket brake chambers as reliable as OEM Bendix or Haldex units?

Quality aftermarket chambers from reputable manufacturers like MGM, Gunite, or Euclid can match OEM performance when properly specified. Look for chambers that meet FMVSS-121 standards and carry DOT certification. Many fleet operators report 3-5 years of service from quality aftermarket units. Avoid extremely cheap no-name brands, as they often have issues with diaphragm failure and corrosion resistance.

What other components should I replace when changing brake chambers?

When replacing brake chambers, inspect and consider replacing: clevis pins and bushings (these wear out and cause slack), mounting brackets if corroded, air hoses if cracked or weathered, and slack adjusters if they're not maintaining proper adjustment. Many technicians recommend replacing chambers in axle sets rather than individually to ensure even braking performance. Also check your glad hands and air dryer while the system is being serviced.
