The 4702 Brake Lining, identified by FMSI# 4702, is a specialized braking component crafted by Dingchi for FORD commercial vehicles and RECKWELL heavy-duty equipment. Engineered to meet the unique demands of these brands, it supports Gross Axle Weight Ratings (GAWR) of 20,000lbs and 23,000lbs, with the capability to handle higher loads for short-duration tasks. Its precise dimensions—381mm drum compatibility, 177.2/171.1mm arc length, 101.6mm width, and 18.7/15.5-17.8/11.0mm thickness—ensure a factory-like fit with FORD and RECKWELL braking systems. Compliant with FMVSS 121, it delivers consistent stopping power, reduces maintenance frequency, and aligns with the reliability expectations of FORD and RECKWELL operators.

Dingchi’s formulation for the 4702 Brake Lining is tailored to the load profiles of FORD commercial vehicles (e.g., FORD F-750 trucks) and RECKWELL equipment (e.g., utility trailers). The material’s high tensile strength resists deformation under heavy loads, ensuring that braking performance does not diminish when hauling construction materials, farm equipment, or other heavy cargo—common use cases for these brands.
Unlike one-size-fits-all linings, the 4702 model is engineered to match the exact specifications of FORD and RECKWELL brakes. The 381mm drum size aligns with the standard drum diameter of many FORD heavy-duty models, while the 177.2/171.1mm arc length and 101.6mm width ensure full contact with the brake drum. The thickness range (18.7/15.5-17.8/11.0mm) balances initial performance and long-term wear, providing a consistent braking feel from installation to replacement.
FMVSS 121 compliance is a core feature of the 4702 Brake Lining. This certification guarantees that the lining meets federal standards for stopping distance, heat resistance, and structural safety—critical for FORD and RECKWELL users who operate in regulated industries (e.g., logistics, construction). The lining also undergoes rigorous quality checks during production, ensuring that each unit performs uniformly, reducing the risk of brake failure or uneven wear.
The 4702 Brake Lining is ideal for FORD’s heavy-duty commercial lineup, including the F-650, F-750, and FORD L-Series trucks. These vehicles are often used for local delivery, construction site transport, or utility services (e.g., water trucks), where frequent stops and heavy loads demand reliable braking. The lining’s compatibility with FORD’s original braking systems eliminates the need for modifications, simplifying installation and maintenance.
RECKWELL specializes in industrial and agricultural equipment, such as farm trailers, construction utility trailers, and small flatbeds. The 4702 model’s high GAWR support and wear resistance make it suitable for these applications, where equipment often operates in harsh environments (e.g., dirt roads, construction sites) and requires durable components to withstand dust, debris, and heavy use.
It is optimized for FORD heavy-duty models with 381mm brake drums, such as the F-650, F-750, and L-Series. For other FORD models (e.g., light-duty trucks), we recommend checking your vehicle’s drum size and FMSI number with Dingchi’s support team to confirm compatibility.
The key differences lie in application and dimensions: the 4702 is designed for FORD/RECKWELL (381mm drum, 101.6mm width), while the 4707 targets ROR/trailers (419mm drum, 177.8mm width). The 4702 also has a narrower thickness range, optimized for the lighter load profiles of FORD commercial vehicles compared to ROR’s heavy cargo.
To maximize service life, inspect the lining every 10,000-15,000 miles for wear (replace if thickness drops below 11.0mm) and clean the brake drum of dust/debris regularly. Avoid overloading your FORD/RECKWELL vehicle beyond its GAWR, as this can accelerate lining degradation.
