2019 International LT — Brake Pad & Rotor Specs

Quick Reference

How to Choose Pads

When it comes to a heavy-duty truck like the 2019 International LT, choosing the right brake pads is paramount for safety, performance, and longevity. The primary types you'll encounter are semi-metallic, ceramic, and specialty heavy-duty options.

• Semi-Metallic Pads: These are often the standard for heavy-duty applications due to their excellent stopping power and high tolerance to heat. They typically contain 30-65% metal by weight, which helps dissipate heat and provides a strong bite. However, they can be noisier than ceramic pads and produce more brake dust. For the International LT, semi-metallic pads are a reliable choice for consistent performance under heavy loads and frequent braking.

• Ceramic Pads: While popular in passenger vehicles for their quiet operation and low dust, ceramic pads are less common as a primary option for severe heavy-duty truck applications. They offer good stopping power and are very quiet, but they may not dissipate heat as effectively as semi-metallic pads under extreme, continuous braking conditions typical of a loaded Class 8 truck. If your International LT operates primarily unladen or in lighter-duty roles, ceramic may be acceptable, but always prioritize the manufacturer's recommendations.

• Heavy-Duty/Fleet Specific Pads: Many aftermarket manufacturers offer pads specifically formulated for heavy-duty trucks and fleet use. These often feature proprietary friction materials designed to withstand the rigors of commercial trucking, including high temperatures, extended braking, and heavy loads. These are usually an enhanced semi-metallic compound or a similar robust formulation. Always look for pads rated for the Gross Vehicle Weight Rating (GVWR) of your International LT.

For the 2019 International LT, prioritizing heavy-duty semi-metallic or application-specific fleet pads that meet or exceed OEM specifications is generally the wisest choice.

Typical Service Life

The service life of brake pads and rotors on a 2019 International LT can vary significantly based on several factors, including:

• Application: Long-haul highway driving typically results in longer brake life than regional delivery, stop-and-go traffic, or mountainous terrain.
• Load: Consistently hauling heavy loads will naturally wear brakes faster than operating unladen.
• Driver Habits: Aggressive braking, sudden stops, and riding the brakes will accelerate wear.
• Maintenance: Proper maintenance, including regular inspections and timely replacement, can help optimize life.

As a general guideline, front brake pads on a heavy-duty truck like the International LT might last anywhere from 30,000 to 80,000 miles or more. Rear pads often last longer due to less braking force distribution. Rotors are typically replaced when pads are replaced, or when they reach their minimum thickness. A
