Caliso BR902018-01 Vented Drum-In-Hat Disc Brake Rotor

The Caliso BR902018-01 is a vented disc brake rotor featuring a drum-in-hat (DIH) design, which integrates a small drum brake surface into the hat section of the rotor to serve as the parking brake mechanism. This configuration is commonly found on rear axle positions of vehicles that use disc brakes for service braking and a drum-type system for the parking brake.

Key Features:

• Vented construction — internal vane channels between the two rotor faces promote airflow and heat dissipation, helping to reduce brake fade under repeated or heavy use
• Drum-in-hat design — integrates a machined drum surface inside the rotor hat for parking brake shoe engagement, maintaining OE-style parking brake function
• Direct-fit replacement — engineered to match the original equipment dimensions, bolt pattern, and hub geometry for straightforward installation
• Cast iron construction — provides the thermal mass, wear resistance, and friction surface quality required for reliable disc brake performance
• OE-style brake surface — machined to accept standard brake pads without requiring pre-installation machining

The Caliso BR902018-01 is a quality replacement rotor designed to restore proper braking performance and parking brake function. As with all vented rotors, it should be replaced in axle pairs to maintain balanced braking.
