Premium Rear Brake Drum MK321338 320x120mm Heavy Duty Brake Drum

Premium Brake Drum MK321338 for Mitsubishi Fuso Canter | 320x120mm Heavy-Duty Rear Axle Component

Product Overview

The MK321338 Brake Drum is a high-precision, heavy-duty replacement component specifically engineered for Mitsubishi Fuso Canter (FE Series) light and medium-duty trucks. Optimized for rear axle braking systems, this drum is critical for ensuring reliable stopping power and maximum vehicle safety under full commercial load conditions.

Manufactured from premium-grade G3000 / HT250 Grey Cast Iron, our MK321338 model features superior thermal conductivity to prevent heat-induced "brake fade" and surface cracking. Each unit is CNC-machined to exacting OEM standards, ensuring a perfect "plug-and-play" fit. This drum is built to handle the rigorous demands of urban delivery cycles and long-haul logistics.

Key Benefits

Enhanced Heat Dissipation: The specialized high-carbon iron alloy allows for rapid energy transfer, keeping the braking surface cool even under heavy-load downhill conditions.

Precision Dynamic Balancing: Every MK321338 drum is factory-balanced to eliminate vibrations at high speeds, protecting wheel bearings and seals from premature wear.

OEM Standard Fitment: CNC-lathed to match original equipment tolerances, ensuring immediate friction alignment with new brake shoes.

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

Anti-Corrosion Finish: (Optional) Treated with a protective coating to prevent oxidation during sea freight and warehouse storage.

Frequently Asked Questions (FAQ)

1. Which vehicle models is the MK321338 Brake Drum compatible with?

The MK321338 Brake Drum is a premium OEM-replacement part specifically designed for Mitsubishi Fuso Canter trucks, particularly within the FE and FG chassis series. It is engineered to meet the exact dimensional standards of Japanese medium-duty commercial vehicles. To ensure a 100% perfect fit, we recommend verifying your vehicle's 6-hole bolt pattern and the pilot diameter against the original part number MK321338 before installation.

2. What are the benefits of the G3000 Grey Iron used in the MK321338?

Our MK321338 drums are manufactured from high-carbon G3000-grade grey cast iron. This material is the industry benchmark for thermal stability. For delivery trucks frequently operating in "stop-and-go" urban traffic, G3000 iron allows the drum to dissipate heat rapidly. This prevents brake fade and significantly reduces the risk of "heat checking" (small surface cracks), ensuring a longer service life for both the drum and the brake linings.

3. Does the MK321338 Brake Drum come dynamically balanced?

Yes, every MK321338 unit undergoes precision dynamic balancing at the factory. For Mitsubishi Fuso trucks, an unbalanced drum can lead to severe chassis vibration and "shudder" during braking. Our pre-balanced drums ensure a smooth, stable rotation that protects your wheel bearings, tires, and hub seals from premature wear, effectively lowering the total cost of ownership (TCO) for fleet operators.

4. How do I know when to replace my MK321338 Brake Drum?

Safety is paramount in commercial logistics. You should inspect the MK321338 during every brake shoe service and replace it if:

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

Surface Distortion: You experience "pedal pulsation," which usually indicates the drum has warped or become "out-of-round" due to extreme heat.

Structural Damage: You see deep grooves or radial cracks that extend through the friction surface.
