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

The first sign of a failing air dryer is often the presence of water or oil in the air system, leading to a spongy brake pedal. If ignored, this can cause brake valves to stick or freeze, impairing braking performance. The ultimate risk is compromised braking ability, increasing the chance of an accident.

Installation Tip

Ensure the air system is fully drained of pressure before disconnecting any lines to prevent injury and loss of components. Do not overtighten the mounting bolts, as this can damage the housing.

Service Note

When replacing the air dryer, it is crucial to drain and inspect the air tanks for moisture and oil contamination.
