OE 81501100227 MAN Heavy Truck Brake Drums High Precision Casting

Heavy-Duty Brake Drum for MAN Trucks - OE 81501100227 | High-Precision Casting for Rear Axles

Product Overview

The 81501100227 Brake Drum is a mission-critical component designed for the demanding braking requirements of MAN heavy-duty commercial vehicles. Manufactured using high-carbon grey iron (GG25/G3000), this drum offers exceptional wear resistance and thermal capacity.

Our manufacturing process ensures that each drum meets or exceeds OEM standards for balance and structural integrity, significantly reducing brake judder and extending the service life of both the drum and the brake linings. This part is specifically engineered for rear axle applications where heat dissipation is paramount.

Vehicle Compatibility

This brake drum is widely used in the European trucking industry, specifically for:

MAN TGA Series (2000-2007)

MAN TGS Series (2007-Present)

MAN TGX Series (2007-Present)

MAN TGL/TGM (Specific heavy-duty configurations)

MAN Bus / Neoplan Lion's City & Starliner series

Note: Please check your chassis number or current part dimensions before purchasing.

Frequently Asked Questions (FAQ)

1. Which vehicle models is the 81501100227 Brake Drum compatible with?

The 81501100227 Brake Drum is a premium OEM replacement part engineered for MAN heavy-duty vehicles, including the MAN TGA, TGS, and TGX series, as well as Neoplan buses. It is designed to match the specific 10-hole mounting requirements of European commercial axles. To ensure a perfect fit, we recommend cross-referencing your vehicle's VIN or checking the original part number 81.50110.0227 or 81501100231 stamped on your current drum.

2. How does the metallurgy of the 81501100227 handle high-load braking?

Our 81501100227 drums are manufactured from high-carbon G3000/G3500 Grey Cast Iron. This advanced material grade is selected for its exceptional thermal conductivity and heat absorption capacity. For MAN trucks carrying maximum payloads, this ensures that the drum dissipates heat quickly, preventing brake fade and resisting the formation of "heat checks" (surface cracks) during long-distance hauling or steep descents.

3. Does the 81501100227 Brake Drum come dynamically balanced?

Yes, every 81501100227 unit undergoes precision dynamic balancing before leaving the factory. In high-speed European transport, even a minor centrifugal imbalance can cause chassis vibration, steering wheel "shudder," and increased wear on wheel bearings and tires. Our pre-balanced drums ensure smooth, stable rotation, which improves driver comfort and extends the service life of your ABS sensors and hub assembly.

4. What is the safety wear limit (Max Dia) for the 81501100227?

Maximum road safety is critical. The Maximum Diameter (Max Dia)—representing the safety wear limit—is cast or stamped onto the outer rim of the 81501100227. During routine brake maintenance, the internal diameter must be measured with a micrometer. If the drum reaches or exceeds the Max Dia, it must be replaced immediately. Using a drum beyond its wear limit reduces its ability to handle heat and increases the risk of structural failure under emergency braking.
