Frequently Asked Questions About International 9300/9370 Disc Brake Parts

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

Our disc brake parts are designed to fit International 9300 and 9370 models from 1987 through 2003. However, there were mid-year changes in some model years, particularly in brake rotor specifications between 1995-1996. We recommend checking your VIN or existing brake part numbers before ordering. If you're unsure, our customer service team can help verify compatibility with your specific truck.

What's the difference between standard and heavy-duty brake rotors for these trucks?

Standard rotors typically measure 15" x 3.5" and work well for normal highway driving and moderate loads. Heavy-duty rotors are 15" x 4" and feature enhanced venting for better heat dissipation, making them ideal for frequent mountain driving, heavy hauling, or stop-and-go city delivery work. The heavy-duty options generally last 20-30% longer under severe use conditions.

Do I need special tools to install these brake components myself?

Basic brake pad replacement requires standard hand tools, but rotor replacement needs additional equipment including a 3/4" drive socket set, brake spring pliers, and ideally a torque wrench capable of 450-500 ft-lbs for proper wheel bearing adjustment. Many customers also find a brake piston compression tool helpful. Complete installation typically takes 2-3 hours per axle for experienced mechanics.

Are aftermarket brake parts as reliable as OEM for International 9300/9370 trucks?

Quality aftermarket brake components from reputable manufacturers like Bendix, Gunite, and Webb meet or exceed OEM specifications. These parts undergo the same FMVSS 121 testing as original equipment. The main differences are typically price (aftermarket is usually 30-40% less expensive) and availability (aftermarket parts are often easier to find in stock).

How do I know when to replace brake rotors versus just the pads?

Measure your rotor thickness at multiple points. International 9300/9370 rotors should be replaced when they reach 1.18" minimum thickness (stamped on the rotor edge). Also replace rotors if you notice deep grooves over 0.060" deep, heat cracks longer than 1.5", or excessive runout causing brake pedal pulsation. As a general rule, rotors typically last through 2-3 sets of brake pads under normal conditions.
