This is a Type 24 long stroke brake diaphragm, a crucial component within the air brake chamber that converts air pressure into mechanical force to apply the brakes. It ensures consistent and reliable brake application across a range of pressures, unlike a torn or leaking diaphragm which can lead to weak or unpredictable braking. Operators may notice a soft or spongy brake pedal, reduced braking power, or an audible air leak from the brake chamber when this part fails.

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 torn or leaking brake diaphragm will initially manifest as a soft or spongy brake pedal, indicating a loss of air pressure. If the leak is significant, braking effectiveness will be noticeably reduced, and an audible air leak may be heard from the affected brake chamber. The primary risk is compromised braking performance, potentially leading to an inability to stop the vehicle safely.

Installation Tip

Carefully inspect the inside of the brake chamber for any sharp edges or debris that could damage the new diaphragm during installation. Ensure the diaphragm is seated evenly around its entire circumference before securing the chamber halves.

Service Note

When replacing a brake diaphragm, it is essential to inspect the brake chamber for cracks, corrosion, and proper operation of the pushrod.
