6Y7956 Disc Friction — Cat 215b 225

This friction disc is a critical component in the braking system, designed to provide the necessary friction for effective deceleration and stopping. Manufactured to exact specifications, it ensures consistent performance and longevity, unlike a worn or degraded friction surface. Operators may notice a gradual increase in stopping distance, a spongy brake pedal feel, or a burning odor from the brakes 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

A failing friction disc will initially manifest as a gradual decrease in braking performance, requiring more pressure on the brake pedal. If the wear continues, it can lead to brake fade under heavy use and potential damage to the brake rotors or drums. The most critical consequence is a severe reduction in stopping power, compromising the safe operation of the equipment.

Installation Tip

Before installing, ensure the mating surfaces of the brake rotor or drum are clean, smooth, and free of any contaminants like oil or grease. Contaminated surfaces will impair initial braking and accelerate wear.

Service Note

When replacing friction discs, it is crucial to inspect brake fluid for contamination and check brake seals for any signs of leakage.
