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 hissing sound from the air system or a gradual loss of air pressure are early indicators of a failing air dryer. If ignored, moisture can build up, leading to sluggish brake response or complete brake system malfunction. This can compromise the vehicle's ability to stop safely.

Installation Tip

Ensure the air system is fully drained of pressure before beginning disassembly. Overtightening the fittings can damage the threads or the dryer housing.

Service Note

Always inspect the air compressor output and air lines for any signs of oil or excessive moisture contamination.
