Frequently Asked Questions About Freightliner FLD SBA Drum Brake Parts

Will these drum brake parts fit my specific Freightliner FLD model year?

These SBA (Set-Back Axle) drum brake parts are designed for Freightliner FLD models from 1989-2007. However, compatibility can vary based on your specific axle configuration and brake size. We recommend checking your VIN or contacting our support team with your truck's model year and axle specifications to ensure proper fitment. Common configurations include 16.5" x 7" and 16.5" x 8.625" brake sizes.

What's the difference between OEM and aftermarket brake drums, and which should I choose?

OEM drums typically feature cast iron construction with precise machining tolerances and longer service life, while quality aftermarket options can offer similar performance at a lower price point. For heavy-duty commercial use or frequent mountain driving, we recommend OEM or premium aftermarket brands like Gunite or Webb. For moderate use applications, standard aftermarket drums provide reliable performance and value. All our drums meet or exceed DOT standards.

Do I need any special tools or equipment to install these brake components?

Yes, proper installation requires specific tools including a brake drum puller, torque wrench capable of 450-500 ft-lbs for wheel bearings, brake spring pliers, and a dial indicator for checking drum runout. You'll also need a way to safely support the vehicle and remove heavy drums (they can weigh 100-120 lbs each). Many customers find it more cost-effective to have a certified heavy-duty mechanic perform the installation.

How do I know when my drum brakes need replacement versus just new shoes?

Drums should be replaced when they exceed maximum diameter specifications (typically stamped on the drum), show heat cracks, scoring deeper than 0.090", or have excessive runout. Most drums can be turned once or twice if wear is minimal. Signs you need new components include brake fade, vibration during braking, or uneven shoe wear. We recommend measuring drum diameter and inspecting for cracks during every brake shoe replacement.

Are brake hardware kits and springs included with these parts?

Brake shoes, drums, and hardware kits are typically sold separately to allow customization based on your needs. We strongly recommend replacing springs, pins, and adjuster hardware when installing new shoes or drums, as worn hardware is a common cause of premature brake failure. Our complete brake service kits include all necessary springs, pins, clips, and adjusters for a complete axle service and often provide better value than buying components individually.
