The 073-01500 Pressure Plate Assembly is an aircraft wheel and brake system component manufactured for Cleveland (Parker Hannifin / Textron Aviation) brake assemblies. It is used as part of a disc brake system, where it helps apply and distribute force from the hydraulic caliper pistons onto the brake linings.

The pressure plate is a structural load-transfer component inside the brake assembly. When hydraulic pressure is applied, the pistons push the pressure plate, which in turn compresses the brake linings against the rotor, generating the friction needed for aircraft braking during landing and taxi operations.

It is typically used in general aviation aircraft brake systems (Cleveland 30-series assemblies, depending on configuration) and is designed for high strength, heat resistance, and dimensional stability under repeated braking cycles.

This part is commonly supplied as a replacement airframe brake component and is often installed during brake overhaul or maintenance when wear or cracking is detected in the original assembly.
