20842990 — Air Brake Compressor 20382345 20842990 85000614 For Volvo Truck Fh12 Fh16 Fh13 Nh12 Fm9 Fm12

This air brake compressor is a vital component responsible for supplying the compressed air required to operate the pneumatic braking system on Volvo trucks. Manufactured to exacting standards, it ensures consistent air generation and system pressure, unlike a worn unit that may struggle to maintain adequate levels. Observable issues with a failing compressor include a slow-to-build air pressure gauge, audible air leaks, or the air dryer expelling excessive moisture.

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 common initial symptom is a noticeable lag in air pressure build-up after starting the engine, or the air pressure gauge not reaching its normal operating range. If left unaddressed, the compressor may fail to supply sufficient air, leading to intermittent braking or the inability to release the parking brake. This can compromise the vehicle's ability to operate safely and reliably.

Installation Tip

Ensure the mounting surface is clean and flat to prevent stress on the compressor body. Do not use excessive force when connecting air lines, as this can damage the fittings.

Service Note

It is highly recommended to replace the air dryer cartridge and inspect all air system hoses and fittings for leaks when installing a new air brake compressor.
