5t6533 Cylinder Kit Wheel — Cat 320C 320D

This wheel cylinder kit is a vital component of the braking system, responsible for applying hydraulic pressure to the brake shoes or pads. Manufactured to meet rigorous Caterpillar specifications, it ensures reliable and consistent braking force, unlike a worn cylinder that may leak fluid or seize. Operators might notice a soft or spongy brake pedal, reduced braking effectiveness, or fluid leaks around the wheel assembly when this part 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

Initial signs of a failing wheel cylinder include a spongy brake pedal or a noticeable decrease in braking power. If ignored, internal seals can fail, leading to brake fluid leaks and potential loss of braking on one wheel. This can compromise the machine's ability to stop safely, increasing the risk of accidents.

Installation Tip

Thoroughly clean the cylinder bore before inserting new seals to prevent damage and ensure a proper seal. Ensure the brake fluid used is the correct type specified for your machine's braking system.

Service Note

Inspect brake shoes, drums or rotors, and brake lines for wear or damage when replacing the wheel cylinder kit.
