This brake piston is a vital component within the hydraulic braking system, responsible for actuating the brake pads or shoes against the rotor or drum. It is constructed from hardened steel to withstand high hydraulic pressures and resist wear, offering superior durability over a corroded or scored piston. Operators may notice a spongy brake pedal, reduced braking effectiveness, or unusual noises during braking if this part is compromised.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A failing brake piston may initially present as a gradual increase in brake pedal travel or a feeling of sponginess. If ignored, this can lead to significantly reduced braking power and potential brake fluid leaks, compromising the safety of machine operation.
Thoroughly clean the inside of the brake caliper bore before installing the new piston to prevent damage to the seals. Never reuse old brake seals, as they are designed for single use and can cause leaks.
Replace the brake caliper seals and inspect the brake pads and rotor/drum for wear or damage at the same time.
