Frequently Asked Questions About Freightliner FLC120 Drum Brake Parts
What years do these drum brake parts fit on the Freightliner FLC120?
Our drum brake parts are compatible with Freightliner FLC120 models from 1989 through 2003. However, there were minor changes in brake specifications between early models (1989-1995) and later models (1996-2003). Always verify your specific year and axle configuration before ordering. If you're unsure, check your VIN or existing brake part numbers, or contact our support team with your truck's details.
Are aftermarket brake drums and shoes as reliable as OEM parts?
Quality aftermarket brake drums and shoes can match or exceed OEM specifications when sourced from reputable manufacturers. We carry both OEM and premium aftermarket options. Our aftermarket drums are typically made from Grade 3000 cast iron and meet or exceed FMVSS 121 standards. The main differences you'll notice are price (aftermarket is usually 30-40% less expensive) and availability (aftermarket parts are often in stock when OEM parts have long lead times).
What tools and experience level do I need to replace drum brakes myself?
Replacing drum brakes requires intermediate mechanical skills and specific tools including a brake spring tool, drum puller, brake adjustment gauge, and proper jack stands rated for commercial vehicles. The job typically takes 3-4 hours per axle for experienced mechanics. Critical steps include proper spring tension, correct shoe adjustment, and ensuring proper brake balance. If you're not comfortable with brake systems, we strongly recommend professional installation as improper installation can lead to brake failure.
How do I know when to replace drums versus just the shoes?
Brake drums should be measured with a drum gauge whenever you replace shoes. Replace drums if they exceed the maximum diameter stamped on the drum (typically when worn 0.120 inches over original diameter), show heat cracks, scoring deeper than 0.03 inches, or have an out-of-round condition exceeding 0.015 inches. Many customers replace drums every second or third shoe change as preventive maintenance. Always replace drums in axle sets to maintain proper braking balance.
What's included in a complete drum brake kit versus individual parts?
Complete drum brake kits typically include brake shoes with linings, return springs, hold-down springs, adjusting screws, and spring hardware. Drums are usually sold separately due to weight and shipping considerations. Some kits also include wheel cylinders and rubber boots. Individual parts are available if you only need specific components. Buying a complete kit often saves 15-20% versus purchasing parts individually and ensures all components work together properly.
