The 4551 Brake Lining, marked with FMSI# 4551 and WVA# 19069/70, is a heavy-duty braking solution developed by Dingchi for YORK and FRUEHAUF—two leading brands in industrial and commercial trailers. Built to handle the rigorous demands of these vehicles, it supports Gross Axle Weight Ratings (GAWR) of 20,000lbs, 23,000lbs, and higher, making it a top choice for fleet operators hauling heavy cargo. Its precision dimensions—419mm drum compatibility, 189.1/194.6mm arc length, 219.1mm width, and 18.2/15.2-17.6/11.1mm thickness—ensure a perfect fit with YORK and FRUEHAUF braking systems. Compliant with FMVSS 121, it delivers smooth, consistent braking, minimizes downtime for replacements, and meets the high reliability standards of YORK and FRUEHAUF users.

Dingchi’s advanced material formulation for the 4551 Brake Lining is engineered to withstand the extreme loads of YORK and FRUEHAUF trailers, which often transport construction materials, shipping containers, or industrial machinery. The lining’s dense composition resists wear and heat buildup during prolonged braking, ensuring that stopping power remains consistent even when the trailer is at maximum weight capacity. This durability reduces the need for frequent maintenance, a key advantage for fleets with tight schedules.
At 219.1mm, the 4551’s width is wider than many standard brake linings—an intentional design choice to increase contact area with the brake drum. This wider contact distributes braking force evenly, reducing stress on both the lining and drum, and minimizing the risk of uneven wear or overheating. The 419mm drum compatibility and 189.1/194.6mm arc length further optimize fit, ensuring that the lining adapts to the specific curvature of YORK and FRUEHAUF drums for maximum efficiency.
The 4551 Brake Lining holds two critical certifications: FMVSS 121 and WVA# 19069/70. FMVSS 121 compliance guarantees it meets U.S. federal safety standards for stopping distance, structural integrity, and heat resistance, while WVA# 19069/70 (a standard from the World Vehicle Association) validates its compatibility with global YORK and FRUEHAUF models. These certifications make the 4551 a trusted choice for both domestic and international fleet operators.
YORK specializes in heavy-duty trailers, including flatbeds, dump trailers, and container carriers, used in construction, mining, and logistics. The 4551 Brake Lining’s high GAWR support and wide design make it ideal for these applications, as it can handle the weight of construction equipment (e.g., excavators) or stacked containers. Its resistance to dust and debris—common in construction and mining sites—also ensures reliable performance in harsh environments.
FRUEHAUF is a pioneer in trailer manufacturing, producing models for freight transport, agricultural use, and waste management. The 4551 model’s durability and FMVSS 121 compliance make it suitable for FRUEHAUF’s long-haul freight trailers, where consistent braking over thousands of miles is essential. It also performs well in agricultural trailers, which often operate on uneven terrain and require robust braking to manage loads of grain, hay, or farm machinery.
It is compatible with YORK and FRUEHAUF models that use 419mm brake drums—a common size in their heavy-duty lines. For smaller YORK/FRUEHAUF trailers with different drum sizes, we recommend checking your trailer’s specifications or contacting Dingchi’s technical team to find the correct FMSI-coded lining.
WVA# 19069/70 is a global standard that ensures brake components meet uniform quality and performance criteria across countries. For fleet operators with international routes, this certification means the 4551 Brake Lining complies with safety regulations in Europe, Asia, and other regions, eliminating the need to source region-specific linings.
Under normal heavy-duty use (e.g., 20,000-25,000 miles per year hauling 23,000lbs loads), the 4551 lining can last 12-18 months. Life expectancy may vary based on driving conditions (e.g., frequent stop-and-go vs. highway driving) and maintenance practices—regular drum cleaning and load adherence will extend service life.
