Abstract
Fluid passages machined in the annular brake piston and in the outboard brake ring of a wet disc brake system allows the circulation of cooling and lubricating fluid. An annular disc brake will deliver cooling fluid to the circumferential periphery of the brake disc operating cavity where the fluid relief passages machined in the annular brake piston and in the outboard brake ring will allow the passage of this fluid out of the brake disc operation cavity thus preventing the stagnation of cooling fluid in the brake disc operating cavity.
