Frequently Asked Questions About International LoneStar Drum Brake Parts

Will these drum brake parts fit my specific year model International LoneStar?

Our International LoneStar drum brake parts are designed to fit 2008-2021 model years. However, there are variations between early models (2008-2012) and later models (2013-2021) due to axle configurations. Always verify your axle manufacturer (Meritor, Dana, or Hendrickson) and brake size (16.5" x 7" or 16.5" x 8.625") before ordering. You can find this information on your axle identification tag or by checking your VIN with your local International dealer.

What's the difference between standard and heavy-duty brake shoes, and which do I need?

Standard brake shoes use 4515 or 4707 friction material and are suitable for highway and regional hauling applications. Heavy-duty shoes feature 4709 or 4720 friction material with higher heat resistance, recommended for severe service applications like logging, construction, or mountain driving. If you frequently haul maximum loads, experience brake fade, or replace shoes more than twice annually, upgrade to heavy-duty options for better longevity and performance.

Can I replace drum brake components myself, or do I need special tools?

While drum brake replacement is possible for experienced mechanics, it requires specific tools including a brake spring tool set, drum puller, brake adjustment gauge, and proper jack stands rated for commercial vehicles. Critical safety measurements like drum diameter and shoe-to-drum clearance must be precise. We recommend professional installation unless you have commercial vehicle experience, as improper installation can lead to brake failure or uneven wear.

How do I know when my brake drums need replacement versus resurfacing?

Measure your drum's inside diameter with a drum gauge. International LoneStar drums typically have a maximum service diameter stamped on the drum (usually 16.620" for 16.5" drums). If your drums measure within 0.060" of this maximum, replace them. Also replace if you notice heat cracks longer than 1.5", blue discoloration from overheating, or out-of-round conditions exceeding 0.015". Drums can typically be resurfaced 2-3 times before replacement.

Are aftermarket drum brake parts as reliable as OEM International parts?

Quality aftermarket parts from reputable manufacturers like Gunite, Webb, or Accuride meet or exceed OEM specifications and often carry equal or better warranties. These parts undergo the same FMVSS 121 testing as OEM components. The key difference is price - aftermarket options typically cost 30-40% less. Always verify the manufacturer meets DOT standards and offers at least a 1-year warranty. Avoid unbranded or suspiciously cheap alternatives that may use inferior casting materials.
