Product Specification

Premium Brake Drum 40206-90166M for Nissan UD Trucks | 406x185mm Heavy-Duty Brake Components

Product Overview

The 40206-90166M Brake Drum is a high-precision, heavy-duty replacement part engineered specifically for Nissan Diesel (UD Trucks) and related commercial vehicle axle systems. As a critical component of the foundation brake system, this drum is designed to provide stable braking performance, high thermal capacity, and extreme durability for demanding transport environments.

Manufactured from high-carbon HT250 / G3000 Gray Cast Iron, our 40206-90166M model is optimized to handle the heavy loads typical of logistics and construction. It features advanced metallurgy that promotes rapid heat dissipation, significantly reducing the risk of brake fade and extending the service life of both the drum and the brake linings.

Key Benefits

Optimized Heat Sink: The specialized iron alloy allows for high thermal energy absorption, preventing surface cracking during heavy-duty braking cycles.

CNC Precision Machining: Every drum is machined to OEM tolerances, ensuring perfect concentricity and eliminating the risk of vibration or "brake pull."

Dynamic Balancing: Factory-balanced to G16 standards to reduce stress on wheel hubs and extend the life of your wheel bearings.

High Wear Resistance: Engineered for long-haul durability, significantly lowering the Total Cost of Ownership (TCO) for fleet managers.

Corrosion Resistance: Features a protective surface finish to prevent rust during shipping and storage in humid environments.

Frequently Asked Questions (FAQ)

1. Which vehicle models is the 40206-90166M Brake Drum designed for?

The 40206-90166M Brake Drum is a premium aftermarket replacement specifically engineered for Nissan UD Trucks. It is commonly found on medium-to-heavy duty UD chassis. To ensure a perfect fit, we recommend verifying your vehicle's 10-hole or 8-hole mounting pattern (depending on the specific series) and checking the pilot diameter against the original equipment (OE) specifications.

2. What material is used to ensure the durability of the 40206-90166M?

Our 40206-90166M drums are manufactured from high-grade G3000 Grey Cast Iron. This material is selected for its high carbon content, which provides excellent thermal conductivity and heat dissipation. This is vital for heavy-duty Nissan UD trucks, as it prevents the drum from warping or developing heat cracks during prolonged braking on steep inclines or in heavy traffic.

3. Does the 40206-90166M Brake Drum come dynamically balanced?

Yes, every 40206-90166M unit undergoes precision dynamic balancing during production. Proper balancing is essential to eliminate centrifugal imbalances that cause steering wheel vibration and "shudder." By installing a balanced drum, you protect your wheel bearings, tires, and suspension components from premature wear, ensuring a smoother and safer driving experience.

4. How do I know when to replace my Nissan UD 40206-90166M Brake Drum?

Regular inspection is key to road safety. You should replace the 40206-90166M if:

The Wear Limit is Reached: The internal diameter meets or exceeds the Maximum Diameter (Max Dia) limit stamped on the outer rim.

Severe Heat Checking: You notice numerous small cracks or any single crack deep enough to catch a fingernail.

Scoring and Grooving: The internal friction surface has deep grooves that cannot be removed by machining without exceeding the wear limit.
