2V9446 Kit-Brake Caliper — Cat 528 528b

This brake caliper kit is a critical component of the braking system, ensuring proper hydraulic pressure is applied to the brake pads. It is manufactured to meet stringent quality standards, providing reliable stopping power that surpasses the performance of a worn or seized caliper. Operators may notice a spongy brake pedal, increased stopping distances, or a pulling sensation during braking when this component begins to fail.

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 spongy or soft brake pedal is often the first sign of a failing caliper kit, indicating internal seal leakage. If ignored, braking performance will continue to degrade, leading to longer stopping distances and potential overheating of the brake system. Continued operation with a compromised caliper can result in uneven brake pad wear and potential brake failure.

Installation Tip

Ensure all caliper mounting surfaces are clean and free of corrosion before assembly to prevent binding. Avoid overtightening caliper bolts, as this can damage the threads or the caliper housing.

Service Note

Inspect brake pads and rotors for wear or damage when servicing the brake caliper.
