Heavy Duty Brake Drum 3502571-AOE For FAW J6 J7 Truck Rear Axle Brake Components

Product Specification

Heavy Duty Brake Drum 3502571-AOE for FAW J6 J7 Trucks | Premium Rear Axle Brake Component

Product Overview

The 3502571-AOE Brake Drum is a high-strength, precision-engineered component designed specifically for FAW (First Automotive Works) heavy-duty trucks and high-end trailer systems. This drum is a vital part of the vehicle's foundation brake system, responsible for converting kinetic energy into thermal energy safely and efficiently.

Cast from premium-grade HT250 / G3000 Gray Iron, our 3502571-AOE model is built to withstand the rigorous braking demands of long-haul logistics and construction transport. It features a high thermal storage capacity to prevent heat cracking and ensuring consistent braking torque even under maximum payload conditions.

Key Benefits

Exceptional Heat Sink Capacity: The extra-wide friction surface (220mm) and high mass allow for rapid heat absorption, significantly reducing brake fade.

Anti-Deformation Structure: Reinforced casting design maintains perfect circularity under high pressure, ensuring smooth braking without vibration.

Precision Balancing: Each drum is factory-balanced to prevent "steering wheel shake" and reduce wear on wheel hubs and seals.

Optimized Surface Finish: The friction surface is fine-lathed to promote quick "bedding-in" with new brake linings, maximizing performance from the first mile.

Long Service Life: Advanced metallurgy offers high wear resistance, leading to longer replacement intervals and lower maintenance costs (TCO).

Frequently Asked Questions (FAQ)

1. Which truck models is the 3502571-A0E Brake Drum compatible with?

The 3502571-A0E Brake Drum is a high-quality OEM replacement primarily designed for FAW Jiefang (J6/J6P series) heavy-duty trucks. It is also compatible with various other commercial vehicles using the same axle specifications. To ensure 100% fitment, we recommend checking the 10-hole bolt circle and the internal diameter against your vehicle's technical manual or verifying the FAW original part number.

2. What makes the 3502571-A0E suitable for heavy-duty hauling?

Our 3502571-A0E drums are cast from high-strength G3000 Grey Iron, specifically formulated to handle the extreme mechanical stress of heavy-load transport. This material offers excellent thermal conductivity, which allows for rapid heat dissipation. By maintaining a stable temperature, the drum prevents thermal expansion and ensures consistent braking performance even during long descents or heavy-traffic conditions.

3. Why is dynamic balancing crucial for the 3502571-A0E Brake Drum?

Every 3502571-A0E unit undergoes precision dynamic balancing before shipment. In heavy-duty trucks, an unbalanced drum can cause significant chassis vibration, leading to premature wear of the wheel bearings, tires, and suspension system. Our balanced drums ensure a smooth, stable rotation, which improves driving comfort and reduces long-term maintenance costs for fleet owners.

4. How do I know when to replace my 3502571-A0E Brake Drum?

You should inspect the 3502571-A0E during every brake shoe replacement. Key indicators for replacement include:

Reaching the Max Dia: If the internal diameter exceeds the Maximum Diameter limit stamped on the drum.

Surface Anomalies: Deep scoring, grooving, or "blue spots" indicating localized overheating.

Heat Cracking: Any cracks that are deep enough to be felt with a fingernail or that extend to the edge of the drum. Replacing worn drums promptly is essential to maintaining the safety and stopping power of your FAW truck.
