Frequently Asked Questions About Kenworth T600 Drum Brake Parts

What year models of Kenworth T600 are these drum brake parts compatible with?

Our Kenworth T600 drum brake parts are designed to fit models from 1988 through 2007. However, there were minor changes in brake specifications between early models (1988-1994) and later models (1995-2007). When ordering, please verify your specific year and whether you have standard 16.5" x 7" brakes or the heavy-duty 16.5" x 8.625" option. You can find this information on your existing brake assembly or in your truck's specification sheet.

How difficult is it to replace drum brake shoes and hardware on a T600, and what tools do I need?

Replacing drum brake components requires intermediate mechanical skills and typically takes 2-3 hours per wheel. Essential tools include a brake spring tool, brake shoe pliers, a large pry bar, and standard hand tools. The most challenging part is usually removing and reinstalling the brake shoe return springs. We recommend having a brake adjustment tool for proper setup after installation. Many customers report that having a second person helps significantly when handling the heavy brake drums.

What's the difference between standard and severe-duty brake shoes for the T600?

Standard brake shoes use a friction material rated for normal highway use and typically last 150,000-200,000 miles. Severe-duty shoes feature a harder, more heat-resistant friction compound designed for heavy hauling, mountain driving, or frequent stop-and-go conditions. They generally last 250,000-350,000 miles but may produce slightly more brake dust. The severe-duty option costs about 20-30% more but is recommended if you regularly haul maximum loads or operate in hilly terrain.

How can I tell when my T600's drum brakes need replacement before they fail?

Key indicators include brake shoes worn to 1/4 inch or less of friction material, visible cracks in the brake drums, excessive brake adjustment frequency (more than once per month), or a brake stroke exceeding 2 inches. During inspection, check for oil contamination on the shoes, which appears as dark staining and requires immediate replacement. Drums should be measured for wear - replace them if they exceed the maximum diameter stamped on the drum (typically 16.620" for standard T600 drums).

Are aftermarket drum brake parts reliable for the Kenworth T600, or should I stick with OEM?

Quality aftermarket brake components from established manufacturers like Gunite, Webb, and Meritor meet or exceed OEM specifications and often cost 30-40% less. These brands use the same friction material formulations and manufacturing standards as original equipment. The main difference is typically the warranty period - OEM parts usually carry a 2-year warranty while aftermarket options offer 1-year coverage. Avoid extremely low-priced options as they may use inferior friction compounds that wear quickly or fade under heavy braking.
