Frequently asked questions about Sinotruk AZ9112440001 brake drum
What material is the AZ9112440001 brake drum made of?
The part is cast from high-strength gray cast iron HT250. This material provides excellent thermal conductivity and resistance to cracking during heating cycles. Thanks to this, the drum evenly removes heat and maintains shape stability throughout its entire service life.
What is the maximum allowable wear for the AZ9112440001 brake drum?
The nominal internal diameter is 420 mm. The maximum permissible wear diameter should generally not exceed 422 mm. When this limit is reached, the drum must be replaced, otherwise braking efficiency is critically reduced.
Can this drum be used on Sinotruk HOWO front axle?
No, brake drum AZ9112440001 is designed exclusively for the rear axle. For the front axle, a part with a different number and smaller dimensions is used. If you need a front brake drum, contact us - we will select the right part number.
How can you tell when it's time to replace your brake drum?
The main signs of wear are: vibration when braking, increased braking distance, characteristic grinding or uneven wear of the brake pads. In addition, at each scheduled maintenance, it is recommended to measure the inner diameter of the drum with a caliper.
Is the AZ9112440001 brake drum compatible with brake pads from other manufacturers?
Yes, provided the pads are the standard size for Sinotruk rear axle with 420mm drum diameter. However, for maximum life and even wear, we recommend using pads that meet OEM specifications.
