6Y2027 Disc-Friction — Cat 120g 12g

This is a CAT Friction Disc, a vital component in the braking system responsible for generating the friction needed to slow or stop the equipment. Manufactured to meet rigorous quality standards, it offers superior wear resistance and consistent performance compared to a worn disc. Operators might observe a delayed braking response, a burning smell from the brakes, or increased stopping distances 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

Early indications of a worn friction disc include a noticeable increase in the distance required to stop the machine. If left unaddressed, the braking performance will continue to degrade, potentially leading to overheating of the brake system and reduced control. Failure to replace worn friction discs compromises the safe operation of the equipment.

Installation Tip

Ensure all mating surfaces are clean and free of debris before installing new friction discs to guarantee proper engagement. Avoid mixing new friction discs with old, worn ones, as this can lead to uneven wear and reduced braking efficiency.

Service Note

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