8Y4387 Lining — Cat 955L

This friction lining is a vital part of the braking system, designed to create the necessary friction against the brake drum or disc to slow or stop the machine. Manufactured to high standards, it offers reliable stopping power and longevity, outperforming worn or degraded original linings. Operators might experience a noticeable increase in braking distance, a squealing or grinding noise during braking, or a soft brake pedal when this lining is failing.

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 indication of worn brake lining is often an audible squeal or grind during braking, accompanied by a longer stopping distance. Continued use will lead to significantly reduced braking effectiveness and potential damage to the brake drum or disc. Inadequate braking capacity poses a risk to equipment and personnel safety.

Installation Tip

Ensure the brake drum or disc surface is clean and free of grease or debris before installing the new lining. Avoid reusing old hardware, as it may be worn or weakened.

Service Note

Inspect the brake drum or disc for scoring or excessive wear, and check the condition of brake shoe return springs when replacing the lining.
