This rear brake drum is critical for maintaining balanced and effective braking on the rear axle of SINOTRUK Howo trucks. Its precision-machined friction surface ensures consistent contact with the brake shoes, delivering smooth, fade-resistant braking performance even under heavy loads and repeated stop-and-go driving conditions. The BJ1050N-AE1 is built to withstand the harsh operating environments typical of long-haul trucking, construction sites, and mining operations, ensuring dependable service over thousands of miles.
OEM direct replacement • Premium gray iron material • High thermal conductivity • Dynamic balance tested
The BJ1050N-AE1 rear brake drum is a critical safety component designed for the rear axle of SINOTRUK Howo heavy-duty trucks. It is manufactured using national standard gray iron 250 material, with a carefully balanced proportion of carbon, silicon, and manganese to achieve optimal mechanical properties. This material composition provides excellent wear resistance, thermal stability, and resistance to cracking under repeated thermal cycling.
The brake drum features a precision-machined friction surface that ensures consistent and even contact with the brake shoes, maximizing braking efficiency and minimizing vibration. The drum is dynamically balanced to ensure concentricity, reducing the risk of brake judder and extending the service life of both the drum and the brake shoes.
Designed to meet or exceed original equipment specifications, the BJ1050N-AE1 guarantees exact fitment and reliable performance. Its robust construction and high-quality materials provide exceptional durability, making it a preferred choice for critical braking applications in SINOTRUK Howo trucks.
The BJ1050N-AE1 rear brake drum is specifically designed for SINOTRUK Howo heavy-duty trucks equipped with drum brake systems on the rear axle. It is compatible with a wide range of Howo models, including Howo A7, T7H, and other heavy-duty series that utilize the same rear brake drum specifications.
This brake drum is ideal for a variety of demanding applications, including long-haul trucking, regional distribution, construction, mining, and other operations where reliable braking performance is essential for safety and productivity. Its robust construction and premium materials ensure consistent performance under heavy loads and in challenging environmental conditions.
When replacing, always verify the brake drum specifications and axle configuration to ensure compatibility. The BJ1050N-AE1 is a direct-fit component that simplifies maintenance and ensures optimal braking performance.
Installing the BJ1050N-AE1 rear brake drum requires proper tools and careful attention to safety procedures. Begin by safely lifting and supporting the vehicle, then remove the wheel and tire assembly to access the brake drum.
Remove the old brake drum by loosening the retaining screws and gently tapping it free. Thoroughly clean the hub mounting surface and inspect the brake shoes, springs, and wheel cylinders for wear or damage. Install the new drum by sliding it onto the hub, ensuring it seats properly against the hub flange. Reinstall the retaining screws and torque them to the manufacturer’s specification.
After installation, adjust the brake shoes to achieve the correct drum-to-shoe clearance. Test the brakes by gently applying the pedal before road testing. Regular maintenance includes inspecting the drum for cracks, scoring, or excessive wear, and measuring the drum’s inner diameter to ensure it remains within the manufacturer’s specified limits.
If the drum becomes worn beyond the maximum allowable diameter, it must be replaced immediately to maintain safe braking performance. Always replace brake drums in pairs on the same axle to ensure balanced braking.
The BJ1050N-AE1 rear brake drum is manufactured in an ISO 9001-certified facility, adhering to the strictest quality control standards. The gray iron material is sourced from approved suppliers and undergoes rigorous inspection for chemical composition and mechanical properties.
Each brake drum is produced using advanced lost foam casting technology, ensuring dimensional accuracy and a smooth surface finish. CNC machining is employed to achieve precise tolerances on critical dimensions, including the friction surface diameter and mounting interface.
Every drum undergoes a dynamic balance test to verify concentricity and minimize vibration during operation. We also perform random sample testing for hardness, thermal conductivity, and fatigue resistance to confirm that the drum meets or exceeds OEM performance requirements.
Our commitment to quality ensures that the BJ1050N-AE1 delivers reliable, consistent braking performance, reducing the risk of brake fade, judder, and premature failure. With a comprehensive warranty, this brake drum offers peace of mind for fleet operators and owner-operators alike.
