1V8279 Disc As-Brake — Cat 834b 836

This brake disc is a key friction element within the braking system, designed to generate the necessary force for deceleration and stopping. Manufactured to precise standards, it offers consistent performance and longevity, resisting heat and wear better than a compromised disc. Operators may experience a soft brake pedal, reduced braking force, or excessive heat and noise from the braking system when this part is worn or damaged.

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 signs of a failing brake disc include a noticeable increase in the distance required to stop the equipment or a feeling of sponginess in the brake pedal. If the condition worsens, braking power will significantly diminish, potentially leading to an inability to stop safely. Operating with severely worn discs risks overheating and damage to other braking system components.

Installation Tip

Ensure that the brake caliper and mounting hardware are thoroughly cleaned and inspected for damage before installing the new disc. Avoid applying excessive force to seat the disc, as this can cause damage.

Service Note

When replacing the brake disc, it is crucial to inspect the brake pads, caliper seals, and hydraulic fluid for any signs of wear or contamination.
