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

Initial signs of failure may include a gradual increase in brake pedal travel or a slight reduction in braking effectiveness. If left unaddressed, the braking system will continue to degrade, leading to significantly longer stopping distances and potential loss of control. Continued operation with a failing brake component poses a serious risk to equipment and personnel safety.

Installation Tip

Ensure the brake system is fully depressurized before beginning disassembly to prevent accidental component movement. Avoid overtightening fasteners, as this can damage the new component or its mounting surface.

Service Note

Inspect brake fluid, seals, and other friction materials for wear or contamination when replacing this component.
