2559265 Disc-Friction — Cat D11R D11T

This friction disc is a vital component within the brake or transmission system, responsible for generating the necessary friction to transmit torque or slow rotation. Manufactured to precise specifications, it offers consistent performance and durability, unlike worn discs that can lead to slipping, overheating, and reduced engagement. Operators may experience delayed engagement, shuddering during operation, or a loss of power when this friction disc 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

Early signs of a failing friction disc include a slight shudder or hesitation during engagement or braking. If ignored, the disc will continue to wear, leading to increased slipping, overheating, and a significant loss of torque or braking effectiveness. This can result in operational downtime and potential damage to other transmission or brake components.

Installation Tip

Ensure all friction surfaces are clean and free of oil or grease before assembly to guarantee proper engagement. Do not mix new and old friction discs within the same clutch pack, as this will cause uneven wear.

Service Note

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