Frequently Asked Questions About International HX Brake Parts & Acc.

What brake pad materials work best for International HX trucks, and how long do they typically last?

For International HX trucks, semi-metallic brake pads are the most popular choice due to their excellent heat dissipation and durability under heavy loads. These typically last 30,000-50,000 miles in normal highway conditions. For severe-duty applications or frequent mountain driving, consider ceramic or severe-duty metallic compounds, which can handle higher temperatures but may wear rotors faster. Always match your brake pad material to your specific application - long-haul highway driving requires different pads than local delivery or construction site work.

Will these brake parts fit my specific International HX model year?

International HX brake components are generally compatible across model years 2017-2024, but there are important variations. The HX515 and HX520 models use the same brake system components, while the HX615 and HX620 may require different rotor sizes and caliper configurations depending on your axle specifications. Always verify your axle manufacturer (typically Meritor or Dana) and brake system type (air disc or drum) before ordering. Check your VIN plate or maintenance records for your specific brake configuration code.

Do I need special tools or professional installation for International HX brake components?

Basic brake pad replacement requires standard heavy-duty tools including a large C-clamp, socket set, and pry bars. However, rotor replacement and caliper work require specialized equipment such as a heavy-duty impact wrench (minimum 1,000 ft-lbs), brake spring tools, and potentially a brake lathe. Air brake systems also require proper bleeding procedures and DOT certification for commercial vehicles. While experienced mechanics can handle pad replacement, we recommend professional installation for complete brake system overhauls to ensure proper adjustment and safety compliance.

What are the differences between OEM and aftermarket brake parts for International HX trucks?

OEM brake parts guarantee exact fit and meet International's original specifications but typically cost 20-40% more than quality aftermarket options. Premium aftermarket brands like Bendix, Meritor WABCO, and Gunite offer comparable performance and often exceed OEM standards for heat resistance and pad life. The main differences are warranty coverage (OEM usually offers longer warranties) and availability (aftermarket parts are often more readily available). For daily commercial use, many fleet operators choose aftermarket parts for cost savings without sacrificing safety or performance.

How do I know when my International HX brakes need replacement?

Key indicators include brake pad thickness below 1/4 inch, visible scoring or heat cracks on rotors, increased stopping distance, or air pressure recovery time exceeding 45 seconds. For drum brakes, listen for metal-on-metal grinding or squealing sounds. Check automatic slack adjusters - if manual adjustment is frequently needed, replacement is due. Most International HX trucks also have brake wear indicators that trigger dashboard warnings when pads reach minimum thickness. Regular 90-day DOT inspections should catch wear issues before they become safety concerns.
