Dingchi’s 4709 Brake Lining is a critical component for EATON heavy-duty vehicles, designed to deliver consistent, reliable braking performance in demanding conditions. As a specialized brake lining, it bears FMSI# 4709 and is tailored to fit EATON’s braking drums (Drum: 419) with precise dimensions: Arc Length 196.1mm, Width 177.8mm, and Thickness 22/15.16mm. What sets this lining apart is its ability to support Gross Axle Weight Ratings (GAWR) of 20,000lbs and 23,000lbs—making it ideal for vehicles carrying heavy loads. It also complies with FMVSS 121, a rigorous U.S. federal standard for commercial vehicle braking systems, ensuring safety and regulatory compliance. Dingchi leverages decades of expertise in commercial vehicle braking to formulate the 4709, focusing on friction stability, wear resistance, and long service life.
Meeting FMVSS 121 requirements means the 4709 Brake Lining undergoes rigorous testing for stopping distance, heat resistance, and durability. This compliance ensures that EATON vehicles equipped with the 4709 meet U.S. safety standards, a must for fleet operators and commercial transport companies.
With the ability to handle GAWR of 20,000lbs and 23,000lbs, the 4709 is built for heavy-duty applications. Its friction material is formulated to distribute weight evenly, preventing excessive wear when the vehicle is fully loaded— a common issue with lower-rated brake linings.
The 4709’s Arc Length (196.1mm), Width (177.8mm), and Thickness (22/15.16mm) are calibrated to fit EATON’s 419 drum perfectly. This precision ensures maximum contact between the lining and drum, translating to consistent braking performance and reducing the risk of noise or vibration.
Dingchi’s proprietary friction formula minimizes friction fade— a phenomenon where braking efficiency drops due to overheating. Even during prolonged braking (e.g., descending steep hills), the 4709 maintains stable friction, ensuring safe stopping power.
EATON trailers used for construction materials, agricultural goods, or industrial equipment often operate at maximum GAWR. The 4709 Brake Lining’s high weight capacity and durability make it the ideal choice for these trailers, preventing premature wear and ensuring safe transport.
Long-haul EATON trucks, which travel thousands of miles weekly, require brake linings that can withstand constant use. The 4709’s stable friction and FMVSS 121 compliance make it suitable for these trucks, reducing maintenance stops and improving operational efficiency.
A: GAWR (Gross Axle Weight Rating) is the maximum weight an axle can safely support. The 4709’s ability to handle 20,000lbs–23,000lbs means it can be used on EATON vehicles with heavy axle loads, preventing lining failure due to overloading.
A: Replacement frequency depends on usage: for EATON trucks traveling 100,000+ miles yearly, the 4709 typically lasts 80,000–100,000 miles. For trailers with frequent heavy loads, replacement may be needed every 60,000–80,000 miles. Regular inspections for thickness (replace when below 15.16mm) are recommended.
A: No, Dingchi’s friction formula reduces brake dust production. This not only keeps wheels cleaner but also minimizes environmental impact and reduces the need for frequent wheel maintenance.
A: Yes, the 4709’s dimensions (Arc Length 196.1mm, Width 177.8mm) are specifically designed for EATON 419 drums. It will fit all standard EATON vehicles using this drum size without modifications.
