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

A pulsating sensation felt through the brake pedal or steering wheel during braking is a common sign of a worn or warped brake disc. If ignored, braking effectiveness will diminish, potentially leading to overheating and increased wear on other brake components. The risk is compromised stopping capability, especially under load or on inclines.

Installation Tip

Ensure the mounting surfaces on the hub and the disc are perfectly clean and free of rust or old gasket material before assembly. Avoid reusing old mounting hardware, as it may not provide adequate clamping force.

Service Note

Inspect the brake pads, caliper slides, and brake fluid for wear or contamination when replacing the brake disc.
