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 plate disc include a slight hesitation during engagement or a subtle reduction in power transmission. If left unaddressed, the disc will continue to wear, leading to increased slippage, overheating, and potential loss of drive or braking function. Continued operation risks damage to other components within the transmission or brake system.

Installation Tip

Ensure all surfaces are meticulously clean and free from any lubricant before installation to achieve optimal friction. Avoid mixing new plate discs with old, worn friction discs in the same assembly.

Service Note

Inspect friction discs, seals, and system fluid for wear or contamination when replacing this component.
