81501100232 Rear Brake Drum MAN Heavy Truck Brake Drums OEM Standard

Product Specification

Heavy-Duty Rear Brake Drum for MAN Trucks - OE 81501100232 | High-Carbon Casting & OEM Standard

Product Overview

The OE 81501100232 Brake Drum is a premium-grade replacement part designed for the demanding braking systems of MAN heavy-duty trucks and buses. As a critical safety component, our brake drum is manufactured using advanced high-carbon grey iron (GG25/G3000) to ensure maximum durability and consistent stopping power.

Each unit undergoes a rigorous precision machining process to achieve perfect concentricity and dynamic balance. This reduces brake noise and vibration, providing a smoother driving experience and minimizing wear on the brake linings. Designed to withstand extreme thermal stress, this brake drum is the ideal choice for long-haul fleet maintenance and heavy-duty transport.

Vehicle Compatibility

This brake drum is engineered for specific MAN commercial vehicle series. It is a direct fit for:

MAN TGA Series (Heavy-duty models)

MAN TGS Series (Chassis and Tipper models)

MAN TGX Series (Long-haul tractors)

MAN Bus / Neoplan (Select coach models)

Recommendation: Always verify the OE number or technical dimensions against your vehicle's service manual before installation.

Extended Component Life: Optimized friction surface finish reduces the "break-in" period and minimizes abrasive wear on brake shoes.

100% Dynamic Balancing: Every drum is pre-balanced at the factory to eliminate high-speed vibration and protect your wheel hubs and bearings.

Corrosion Protection: Finished with an anti-rust coating to ensure the product remains in pristine condition from our warehouse to your axle.

ISO/IATF 16949 Certified: Manufactured under strict quality management systems to guarantee OEM-level performance.

Frequently Asked Questions (FAQ)

1. Which vehicle models is the 81501100232 Brake Drum compatible with?

The 81501100232 Brake Drum is a high-performance replacement part specifically designed for MAN heavy-duty trucks, including the TGA, TGS, and TGX series. It is also the standard OEM-spec drum for Shacman F3000 and X3000 trucks using MAN-technology axles. To ensure a 100% perfect fit, we recommend verifying the 10-hole mounting pattern and the 410mm internal diameter against your original MAN part number 81.50110.0232 or 81.50110.0214.

2. Is the 81501100232 designed for the front or rear axle?

While applications can vary by chassis, the 81501100232 is most commonly utilized as a Front Axle Brake Drum for MAN and Shacman commercial vehicles. It features a specialized height of 232mm to accommodate the front hub assembly. Installing a precisely matched front drum is essential for maintaining balanced steering geometry and preventing "brake pull" during emergency stops.

3. How does the G3000 casting material benefit heavy-duty operation?

Our 81501100232 drums are manufactured from premium G3000 Grey Cast Iron, providing the high thermal mass required for heavy-tonnage logistics. This material ensures excellent thermal conductivity, which allows the drum to dissipate heat rapidly during long descents or heavy-traffic hauling. By keeping temperatures stable, it prevents brake fade and resists structural "bell-mouthing," extending the service life of your brake linings.

4. Does the 81501100232 Brake Drum come factory balanced?

Yes, every 81501100232 unit undergoes rigorous precision dynamic balancing before shipment. For MAN trucks operating at high speeds, an unbalanced drum can cause severe steering wheel vibration and accelerated wear on wheel bearings and hub seals. Our pre-balanced drums ensure a smooth, quiet rotation, which improves driver comfort and protects the vehicle's ABS and suspension systems from vibration damage.
