3558990 Disc-Friction — Cat 735b 740b

This is a friction disc, a vital element within the brake or clutch system responsible for generating the necessary friction for engagement and torque transfer. Manufactured to high standards, it provides reliable performance and durability, outperforming worn or glazed discs. Operators might experience issues like delayed engagement, slipping under load, or a burning smell from the brake/clutch assembly.

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 worn friction disc include a slight delay in brake or clutch engagement or a subtle increase in stopping distance. If ignored, the disc will continue to wear, leading to significant slippage, overheating, and a potential loss of braking or drive function. Continued operation risks severe damage to other brake or clutch components.

Installation Tip

Ensure all friction surfaces are clean and free of grease or oil before installation to guarantee proper engagement. Do not mix new friction discs with old, worn ones within the same assembly.

Service Note

Inspect mating plates for flatness and wear, and check brake/clutch fluid condition during replacement.
