Caliso BR31353-01 Solid Drum-In-Hat Rear Disc Brake Rotor

The Caliso BR31353-01 is a solid disc brake rotor featuring an integrated drum-in-hat (DIH) design, engineered as a direct OEM-style replacement for rear brake applications. The drum-in-hat construction incorporates the parking brake drum directly into the rotor hat, allowing the vehicle's existing drum-style parking brake mechanism to function without modification.

Built from high-quality cast iron, this full-cast solid rotor delivers consistent, reliable stopping power and long service life. The non-directional swirl finish on the braking surface eliminates the need for machining prior to installation and promotes proper pad bedding for quieter, more even brake performance from the start.

Key Features:

• Solid rotor construction — designed for rear axle applications with lower heat loads
• Drum-in-hat (DIH) design — integrates parking brake drum functionality into the rotor hat
• Full cast iron construction — engineered to meet OEM metallurgical standards for strength and durability
• Non-directional swirl finish — ready to install without pre-machining; promotes even pad break-in
• Corrosion-resistant coating on hat and edge for extended protection against rust and premature wear
• Precision balanced — minimizes vibration and brake noise for a smooth, quiet ride
• OEM-style fitment — engineered for direct replacement with no modifications required
• May include additional inspection or set screw holes depending on application

For best braking results, it is recommended to replace brake pads at the same time as rotors and to clean the hub face thoroughly before installation to prevent rotor runout.
