2262826 Disc-Friction — Cat 784b 784c

This friction disc is a vital element within the braking system, responsible for generating the necessary friction to slow or stop the heavy-duty equipment. Manufactured to meet stringent Caterpillar standards, it provides robust performance and longevity, unlike a worn disc that may have reduced friction material or exhibit signs of glazing. Operators may experience a spongy brake pedal, reduced braking effectiveness, or a burning odor when this component 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

The first indication of a failing friction disc is often a noticeable increase in stopping distance or a less responsive brake pedal. If ignored, the braking performance will continue to degrade, potentially leading to overheating of the brake system and reduced control. Continued operation with severely worn friction discs can compromise the safe operation of the equipment, especially when carrying heavy loads or operating on inclines.

Installation Tip

Ensure all surfaces that the friction disc contacts are perfectly clean and free of any oil or grease. Improper seating or misalignment can lead to premature wear and reduced braking performance.

Service Note

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