What Do Kenworth T680 Brake Chamber Accessories Do?
Every component in your Kenworth brake system works together to deliver precise, controlled stops. Here's how they function: - Air Chambers with Pushrods: convert compressed air into mechanical force, applying pressure to your brakes. A damaged chamber means slower reaction times and reduced brake efficiency. - Exhaust Brake Actuators: help reduce wear on service brakes by using engine compression to slow the truckâespecially helpful on downhill grades. - Rubber Brake Hoses & Hose Fittings: deliver pressurized air from the system to the brake chambers. Cracked or leaking hoses compromise braking power. - Slack Adjusters: automatically maintain proper brake shoe distance from the drum, keeping your brakes responsive and in regulation. - Brake Boosters & Couplers: assist in building and distributing the air pressure needed to apply your service brakes consistently and safely.Why Go Aftermarket?

Will these brake chambers fit my specific year model T680, and are there differences between model years?
Brake chambers for the Kenworth T680 are generally compatible across model years 2013-present, but there are important variations. Early models (2013-2015) may use Type 20 or Type 24 chambers, while newer models often use Type 30. Always verify your existing chamber size by checking the stamped numbers on your current chambers or consulting your VIN-specific parts diagram. Day cab and sleeper models may also have different configurations, particularly on the rear axles.
What's the difference between standard and long-stroke brake chambers, and which do I need?
Standard brake chambers typically have a 2.5-inch stroke, while long-stroke chambers extend to 3 inches. Long-stroke chambers are required on most T680s manufactured after 2015 due to FMVSS-121 regulations. You can identify your requirement by measuring the pushrod travel or checking the data tag on your existing chamber. Long-stroke chambers provide better braking performance and reduced maintenance but must be paired with compatible slack adjusters.
Can I install these brake chambers myself, or do I need special tools?
While brake chamber replacement is possible for experienced mechanics, it requires specific tools including a caging bolt tool, proper torque wrenches, and air pressure gauges. The job involves working with compressed air systems that can be dangerous if mishandled. Most installations take 45-90 minutes per chamber. Critical steps include proper bleeding, stroke adjustment, and torque specifications (typically 45-50 ft-lbs for mounting bolts). We strongly recommend professional installation for safety and DOT compliance.
What causes premature brake chamber failure on the T680, and how can I prevent it?
Common failure points include diaphragm rupture from moisture contamination, spring brake section corrosion, and pushrod seal leaks. T680s operating in harsh winter conditions are particularly susceptible to moisture-related failures. Prevention includes daily air tank draining, annual brake chamber inspection, maintaining proper air dryer function, and using quality air line antifreeze in cold climates. Replace chambers showing any signs of air leaks, as small leaks quickly become major failures.
Are aftermarket brake chambers as reliable as OEM Bendix or MGM chambers?
Quality aftermarket chambers from established manufacturers like Haldex, Gunite, and TSE can match OEM performance at 30-40% less cost. Look for chambers that meet FMVSS-121 standards and carry DOT certification markings. Key quality indicators include welded (not crimped) construction, zinc-plated or e-coated finish for corrosion resistance, and included mounting hardware. Avoid extremely cheap options as they often use inferior diaphragm materials that fail prematurely in extreme temperatures.
