2399956 Brake Disc — Cat cS-531c cS-531D

This brake disc is a vital friction surface within the braking system, responsible for converting kinetic energy into heat to slow or stop the equipment. Manufactured to precise standards, it provides consistent stopping power and resists premature wear better than a scored or warped disc. Operators may notice a high-pitched squeal, reduced braking performance, or pulsations felt through the brake pedal when this disc is compromised.

Installation & Application Notes

Always replace brakes in axle sets. Bed-in new brake pads with 8–10 moderate stops from 40 km/h. Check disc runout with a dial gauge — maximum 0.1 mm. Inspect caliper slides and pistons when replacing pads.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a worn or damaged brake disc might be an audible squealing or grinding noise during braking. If ignored, the disc can develop grooves or become warped, leading to reduced braking efficiency and potential damage to brake pads. Continued operation risks compromised control and increased stopping distances.

Installation Tip

Always clean the wheel hub mounting surface thoroughly to ensure the disc sits perfectly flat. Never install a brake disc without checking its runout with a dial indicator.

Service Note

When replacing the brake disc, inspect the brake pads or calipers for wear and ensure the brake fluid is clean and at the correct level.
