3T4703 Brush As — Cat 140G 14G

This brush assembly is a vital part of the braking system, responsible for applying pressure to the brake discs or drums to create stopping force. Manufactured to high standards, it ensures consistent performance and longevity, unlike worn brushes that can lead to uneven braking or premature failure. Operators might observe a grinding noise during braking, a stiff or unresponsive brake pedal, or a gradual loss of braking effectiveness when this part is worn.

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

Early indications of a failing brush assembly include a slight hesitation in brake engagement or a faint squealing sound during operation. If left unaddressed, the braking system will become increasingly unreliable, potentially leading to inconsistent stopping power and longer stopping distances. Failure to address this can compromise the equipment's ability to stop safely under load.

Installation Tip

Ensure that the brush holder and its mounting surfaces are clean and free from debris before installation. Do not force the assembly into place; it should fit smoothly if correctly aligned.

Service Note

When replacing the brush assembly, it is advisable to inspect the brake drum or rotor for scoring and check the brake fluid for contamination.
