Caliso BR31286-01 Rear Solid Drum-In-Hat Disc Brake Rotor

The Caliso BR31286-01 is a rear solid disc brake rotor featuring a drum-in-hat (DIH) design, making it a direct-fit replacement for vehicles equipped with a combined disc/drum rear brake system. The drum-in-hat configuration integrates a small internal drum within the rotor hat to accommodate the parking brake mechanism, delivering a clean, OE-style replacement without modification.

Key Features:

• Solid rotor construction — designed for rear axle applications where vented rotors are not required
• Drum-in-hat design — integrates parking brake drum functionality into the rotor hat for OE-equivalent brake system compatibility
• Cast iron construction — provides consistent thermal performance and long service life
• Non-directional braking surface finish — eliminates the need for pre-installation machining and promotes proper brake pad bedding
• Hub-centric fit — precision-machined center bore for accurate, vibration-free mounting
• Direct-fit replacement — engineered to match OE dimensions, bolt pattern, and overall geometry

The BR31286-01 is a reliable, straightforward replacement rotor for maintaining safe and consistent rear braking performance. Its solid design and drum-in-hat integration make it well suited for vehicles where the rear parking brake operates on the inner surface of the rotor hat.
