One New Aftermarket Replacement Brake Piston for Caterpillar (Cat) Excavators
This aftermarket replacement brake piston (Piston-Brake) is designed for use in the swing parking brake system on Caterpillar mid-size hydraulic excavators. The brake piston engages and releases the swing motor parking brake, holding the upper structure stationary when the machine is not actively swinging. A worn or damaged brake piston can result in loss of swing holding force, brake drag, or hydraulic leakage.
