1578412 Disc-Friction — Cat 735 770g

This friction disc is a critical component within the brake system, designed to engage and disengage braking force. It is manufactured to meet stringent material and performance standards, ensuring superior durability and consistent friction compared to a worn or glazed disc. Operators may notice a spongy brake pedal, increased stopping distances, or a burning smell when this part begins to fail.

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

Initial signs of a failing friction disc include a gradual increase in stopping distance and a slight sponginess in the brake pedal. If ignored, the braking performance will continue to degrade, potentially leading to overheating of the brake components. Continued operation with a severely worn disc risks significant damage to other brake system parts and reduced operational safety.

Installation Tip

Ensure the mating surfaces of the brake drum or caliper are thoroughly cleaned and free of debris before installation. Avoid overtightening fasteners, as this can warp the disc or damage the threads.

Service Note

Inspect brake plates, seals, and brake fluid for wear or contamination when replacing friction discs.
