Frequently Asked Questions About Kenworth T680 Brake Parts & Acc.
Will these brake parts fit my specific year model T680?
Most brake components for the Kenworth T680 are compatible across model years 2013-present, but there are important exceptions. Air disc brake systems changed in 2016, and some ABS sensor configurations vary between 2013-2015 and 2016+ models. Always verify your truck's build date and brake system type (drum vs. disc) before ordering. Check your VIN or door jamb sticker for the exact production date, as mid-year changes can affect compatibility.
What's the difference between OEM and aftermarket brake pads, and which should I choose?
OEM brake pads typically use ceramic or semi-metallic compounds that match factory specifications, offering predictable performance and longevity (usually 150,000-200,000 miles). Aftermarket options vary widely - premium brands like Bendix and Meritor often match or exceed OEM quality at lower prices, while economy pads may only last 80,000-100,000 miles. For heavy-haul applications or mountainous routes, invest in severe-duty rated pads regardless of brand. Budget pads work fine for highway-only operations with lighter loads.
Can I replace brake chambers myself, or do I need special tools?
Brake chamber replacement requires specific tools including a caging bolt tool, proper size wrenches (typically 3/4" and 7/8"), and ideally a torque wrench for proper installation. The job is manageable for experienced mechanics but involves compressed air systems that can be dangerous if mishandled. You'll need to cage the spring brake before removal, properly align the pushrod, and ensure correct stroke adjustment after installation. Many drivers tackle this job successfully, but first-timers should have the service manual handy or work alongside an experienced technician.
How do I know when my slack adjusters need replacement versus just adjustment?
Automatic slack adjusters should maintain proper brake stroke without manual adjustment. If you're constantly readjusting them (more than once every 30,000 miles), replacement is needed. Look for these failure signs: excessive play in the clevis pin connection, visible grease leaks, inability to maintain adjustment after proper installation, or physical damage to the worm gear teeth. Quality replacement slack adjusters from Haldex or Meritor typically last 300,000-500,000 miles with proper maintenance. Never manually adjust automatic slack adjusters as a temporary fix - this masks underlying problems.
What's included in a complete brake overhaul kit, and when should I use one?
A complete brake overhaul kit typically includes brake shoes/pads, hardware springs, pins, bushings, cam bushings, and sometimes drums or rotors. Most fleets perform complete overhauls every 250,000-350,000 miles or when brake lining reaches 1/4" thickness. Using a complete kit ensures all wear components are replaced together, preventing premature failure of new parts due to worn hardware. Individual component replacement works for minor repairs, but if you're pulling wheels for major brake work, the labor savings of doing everything at once usually justifies the complete kit cost.
