Frequently Asked Questions About International LT Disc Brake Parts

What brake components are compatible with my specific International LT model year?

International LT models from 2017 to present use standardized disc brake systems, but there are variations. Models equipped with Bendix ADB22X air disc brakes require different pads and rotors than those with Meritor EX+ systems. Always verify your brake system type by checking the brake caliper casting numbers or your vehicle's build sheet. Most 2017-2019 models came with Bendix systems, while 2020+ models may have either Bendix or Meritor depending on specifications.

How difficult is it to replace brake pads and rotors on an International LT?

Replacing disc brake components on an International LT requires intermediate mechanical skills and specific tools. You'll need a 3/4" or 19mm hex socket for caliper bolts, a brake piston compression tool, and proper jack stands rated for commercial vehicles. The job typically takes 2-3 hours per axle. Key challenges include safely compressing the brake pistons and ensuring proper torque specifications (typically 250-300 ft-lbs for wheel nuts). We recommend having a service manual for your specific brake system on hand.

What's the difference between OEM and aftermarket brake parts for the International LT?

OEM brake components meet International's exact specifications and typically last 150,000-200,000 miles under normal conditions. Quality aftermarket options from manufacturers like Bendix, Meritor, and Webb can match OEM performance at 20-30% lower cost. Key differences include pad compound (ceramic vs. semi-metallic), rotor thickness tolerances, and warranty coverage. Avoid economy-grade parts that may have inconsistent friction coefficients or shorter service life, especially for heavy-haul applications.

How often should I inspect and service my International LT's disc brakes?

Federal regulations require brake inspections every 90 days or 25,000 miles for commercial vehicles. For International LT disc brakes, measure pad thickness monthly - replace when worn to 3mm. Rotors should be measured for thickness and checked for heat cracks every 6 months. Warning signs include brake stroke exceeding 2 inches, uneven pad wear, or vibration during braking. Most fleets report replacing pads every 200,000-300,000 miles and rotors every 400,000-500,000 miles under typical highway conditions.

Can I upgrade my International LT from drum brakes to disc brakes?

Converting from drum to disc brakes on an International LT is technically possible but requires significant investment and expertise. The conversion involves replacing wheel hubs, installing new brake chambers, routing new air lines, and potentially updating the ABS system. Complete conversion kits range from $3,000-$5,000 per axle. Most importantly, any brake system modifications must maintain FMVSS 121 compliance and may require DOT certification. For most operators, it's more cost-effective to specify disc brakes when ordering new equipment.
