Frequently Asked Questions About Mack CH/CHN/CHU Truck Brake Parts & Accessories
Will these brake parts fit my specific Mack CH model year?
Our Mack CH/CHN/CHU brake parts are designed to fit models from 1988 through 2007. However, there are variations between early and late model years. For CH models 1988-1999, most brake components are interchangeable. For 2000-2007 models, some ABS-equipped trucks may require specific brake chambers or slack adjusters. Always check your VIN number and existing part numbers before ordering, or contact our support team with your truck's details for verification.
What's the difference between standard and heavy-duty brake chambers for these trucks?
Standard brake chambers (Type 24 or 30) are suitable for most highway and regional hauling applications. Heavy-duty chambers provide approximately 25% more braking force and are recommended for severe service applications like logging, heavy hauling, or mountainous terrain operation. If your Mack CH regularly carries loads over 70,000 lbs or operates in steep grade conditions, heavy-duty chambers are the better choice. Check your current chamber size stamped on the housing before ordering replacements.
Do I need special tools to install these brake components?
Basic brake component replacement requires standard mechanic tools plus a few specialized items. You'll need a cage bolt tool for brake chambers, proper size wrenches for slack adjusters (typically 9/16" square), and a torque wrench capable of 450-500 ft-lbs for certain components. Spring brake chambers require extra caution and should be caged before removal. We recommend having shop air available for testing. If you're replacing brake shoes, a brake shoe tool set will make the job significantly easier.
How do I know when to replace brake chambers versus just the diaphragm?
If your brake chamber is leaking air, check the pushrod seal first. Minor leaks at the seal can often be fixed with a diaphragm kit, which costs about 75% less than a complete chamber. However, if the chamber housing shows corrosion, cracks, or the pushrod has excessive play (more than 1/8" side-to-side movement), replace the entire chamber. Also, if the chamber is over 7 years old and showing any issues, complete replacement is recommended for reliability.
Are aftermarket brake parts reliable for Mack CH trucks, or should I stick with OEM?
Quality aftermarket brake components from established manufacturers like Bendix, Haldex, and MGM meet or exceed OEM specifications and often cost 30-50% less. These parts use the same friction materials and manufacturing standards as original equipment. The key is ensuring DOT compliance and proper specifications. All brake parts we carry are DOT certified and match OEM performance standards. For critical components like ABS valves or electronic controls, OEM may be preferable, but for chambers, slack adjusters, and brake shoes, quality aftermarket options provide excellent value and reliability.
