43512-3990M Performance Drum Brakes 410x220mm Truck Brake Parts

Product Specification

Premium Brake Drum 43512-3990M for Hino 700 Series | 410x220mm Heavy-Duty Truck Brake Parts

Product Overview

The 43512-3990M Brake Drum is a precision-engineered replacement component designed specifically for Hino 700 Series (Profia) and other high-capacity Hino heavy-duty trucks. This model is built to deliver exceptional braking torque and high structural integrity under the most demanding load conditions.

Manufactured from high-grade G3000 / HT250 grey cast iron, our 43512-3990M drum is optimized for maximum heat dissipation and thermal stability. It effectively prevents "brake fade" and surface cracking during prolonged braking on steep descents. Each drum is CNC-machined to exacting OEM standards, ensuring a perfect "plug-and-play" fit for international fleet maintenance and distributors.

Key Benefits

Advanced Thermal Resistance: High-carbon iron composition allows the drum to absorb and dissipate heat rapidly, reducing the risk of thermal cracking.

Precision Dynamic Balancing: Each drum undergoes factory dynamic balancing to eliminate vibrations, which protects your wheel bearings and tires from premature wear. 

Structural Durability: Engineered with a reinforced flange to maintain perfect circularity even under extreme mechanical pressure and high temperatures. 

OEM Standard Compliance: Manufactured according to IATF 16949 quality standards to match the performance and life cycle of the original equipment.

Ready for Installation: The fine-lathed friction surface ensures a smooth "bedding-in" process with new brake linings, providing immediate stopping performance.

Frequently Asked Questions (FAQ)

1. Which vehicle models is the 43512-3990M Brake Drum compatible with?

The 43512-3990M Brake Drum is a premium OEM-replacement part specifically designed for Hino 700 Series (Profia) and other heavy-duty Japanese truck axles. It is engineered to meet the exact load-bearing requirements of long-haul transport. To ensure a 100% perfect fit, we recommend verifying the 10-hole mounting pattern and checking the pilot diameter against your original Hino part number 435123990.

2. What makes the 43512-3990M resistant to high temperatures?

Our 43512-3990M drums are manufactured from high-carbon G3000/G3500 Grey Cast Iron. This specialized material offers superior thermal heat capacity, allowing the drum to absorb and dissipate the immense heat generated by heavy-duty braking. This prevents brake fade and significantly reduces the risk of "heat checking" (surface cracks), ensuring reliable stopping power even when the vehicle is at its maximum Gross Vehicle Weight (GVW).

3. Does the 43512-3990M Brake Drum come dynamically balanced?

Yes, every 43512-3990M unit undergoes rigorous precision dynamic balancing at the factory. For heavy-duty Hino trucks, an unbalanced drum can lead to severe chassis vibration and "pedal pulsation," which can damage wheel bearings and hub seals. Our pre-balanced drums ensure a smooth, stable rotation that extends the life of your entire wheel-end assembly and improves driver comfort.

4. How do I identify when it is time to replace my 43512-3990M Brake Drum?

You should inspect the 43512-3990M during every brake shoe service. Replacement is necessary if:

Wear Limit Reached: The internal diameter meets or exceeds the Maximum Diameter (Max Dia) limit cast onto the drum’s exterior.

Structural Cracks: You see radial cracks that extend through the thickness of the casting.

Distortion: The drum has become "out-of-round" due to extreme heat, causing noticeable vibration during braking. Timely replacement is essential to maintaining the safety and compliance of your commercial vehicle fleet
