Brake Drums

When you’re hauling thousands of pounds down the highway, stopping power isn’t optional – it’s everything. 

 

At Fitzgerald Truck Parts, we know that brake drums for semi trucks aren’t just another part of the system – they’re the barrier between control and catastrophe. Brake drums play a central role in a semi’s air brake system, providing the contact surface needed for brake shoes to create the friction that brings massive rigs to a stop. 

 

Over time, even the toughest drums wear down from repeated heating and cooling cycles, heavy loads, and harsh terrain. These worn drums not only reduce braking performance but also accelerate wear on other components, from shoes to bearings. 

 

If you’ve noticed vibration, delayed braking, or visible cracking or scoring on your drums, it’s time for an upgrade. We offer only the most reliable, road-tested brake drums for semi trucks to keep your rig safe, compliant, and performance-ready.

Understanding Semi Truck Brake Drum Types

We stock a full inventory of brake drums for sale, designed for fitment across all major commercial truck brands. You'll find standard sizes like 16.5x7 and 16.5x8.62, built to match common axle configurations in highway and vocational trucks.

Most brake drums for trucks are made from high-strength cast iron due to its exceptional heat resistance and durability under load. However, modern composite drums offer advantages in reduced weight and improved heat dissipation, especially for operators looking to lower fuel costs and increase payload.

Our team can help you compare OEM drums with aftermarket brake drums from industry-trusted names like Webb, Gunite, and Automann. These alternatives often meet or exceed original specs while offering added value, particularly for high-volume or mixed-fleet operations.

Brake Drum Compatibility and Fitment

Finding the correct drum isn't just about size -- it's about exact fit. Each heavy duty brake drum must match your truck's bolt circle, pilot diameter, brake shoe width, and mounting type. Even a small misalignment can lead to excessive vibration, premature wear, or brake fade under pressure.

We carry a wide selection of drums to fit steer, drive, and trailer axles across multiple makes and models. With our intuitive product filters and spec tools, you can easily narrow your search to find the right match for your system.

Installing the wrong drum can compromise the entire brake assembly. Don't take chances with a mismatched part -- get the perfect fit and peace of mind from our experts who will find the best compatibility and fitment.

Maintenance and Replacement Best Practices

To keep your semi in peak condition, brake drums should be inspected regularly for cracks, heat checks, out-of-round distortion, or scoring. If your drum is out of spec or shows signs of structural fatigue, it's time for a replacement.

During brake service, we also recommend replacing associated components like hardware kits, brake shoes, and hub seals. This helps prevent premature failure and keeps your system operating smoothly. For fleet operators, carrying a few semi brake drums on hand minimizes downtime and keeps trucks rolling when a quick swap is needed.

No matter if you're running cross-country or staying local, our team can help you prepare with dependable parts and sound advice.

Brake Drums and On-Road Safety

Brake drums are a safety-critical component. A worn or cracked drum can't handle the stress of emergency braking, especially when hauling a full load on steep grades. That's why inspections by the FMCSA pay close attention to drum condition during compliance checks.

Quality commercial truck brake drums help maintain consistent stopping power, reduce the risk of brake fade, and contribute to better control in all weather and road conditions. Upgrading to high-performance models is also smart for operators traveling mountainous routes or carrying heavy freight across long distances.

Keeping your braking system in top shape is more than good maintenance -- it's essential to protecting your drivers and meeting regulatory expectations.
