1589430 Brake Drum | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta brake drum, part number 1589430, supplied as a direct replacement for the earlier 1584132 brake drum (8 x 15 1/2). It provides the rotating friction surface that the brake shoes act against within a drum brake assembly. Fitment is carried over from the part it replaces, covering D120 and TD120 series engine installations.

⚙️ Key Features

• OEM Volvo Penta part number 1589430
• Supersedes and directly replaces part number 1584132 (brake drum 8 x 15 1/2)
• Net weight 62 kg
• Fits D120 and TD120 series engine applications

🔌 Function

The brake drum rotates with the wheel or shaft and provides the internal friction surface against which the brake shoes are forced to slow or hold the assembly. It also absorbs and dissipates the heat generated during braking.

⚠️ Common Signs of Failure

• Deep scoring, grooving or ridging of the internal friction surface
• Vibration, pulsation or juddering under braking caused by an out-of-round or oval drum
• Heat checking, bluing or cracking of the drum from repeated overheating
• Squealing, grinding or rumbling noise during brake application
• Inner diameter worn beyond the maximum service limit, reducing braking effectiveness

🛠️ Service Notes

• Inspect the drum's internal bore for scoring, heat-cracking and out-of-round wear before refitting; do not skim/machine it beyond the manufacturer's maximum bore diameter, as this reduces wall thickness and heat capacity.
• When fitting a replacement drum, check the brake shoes, return springs and pins at the same time - a worn or heat-damaged drum is usually accompanied by worn linings.
