5g1297 Cylinder As-Master — Cat 910

This is a master cylinder assembly for the brake system, responsible for converting pedal force into hydraulic pressure to actuate the brakes. It is manufactured to meet stringent quality standards, ensuring reliable performance compared to a worn unit exhibiting a spongy pedal or reduced braking effectiveness. Operators may notice a soft or sinking brake pedal, or a significant loss of stopping power when this component fails.

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 indication of a failing master cylinder. If ignored, braking performance will continue to degrade, requiring more pedal effort for less stopping power. Continued operation with a compromised master cylinder risks extended stopping distances and potential loss of control.

Installation Tip

Ensure the master cylinder reservoir is clean before filling to prevent debris from entering the brake system. Avoid overtightening brake line fittings, as this can strip threads or crack the cylinder body.

Service Note

Inspect brake fluid level and condition, and check brake lines for leaks or damage when replacing the master cylinder.
