Caliso BR901750-01 Solid Drum-In-Hat Rear Disc Brake Rotor

The Caliso BR901750-01 is a solid, drum-in-hat (DIH) rear disc brake rotor engineered as a direct-fit replacement for vehicles requiring a 342mm rotor. The drum-in-hat design integrates the parking brake drum within the rotor hat, making it a precise match for vehicles that use a separate internal parking brake mechanism alongside the disc braking system.

This rotor is manufactured from full cast iron for excellent strength, rigidity, and heat dissipation under repeated braking cycles. The braking surface features a non-directional swirl finish that eliminates the need for pre-installation machining and promotes even, consistent pad break-in from the first use.

Key Features:

• 342mm (13.46 in.) outside diameter — rear position fitment
• Solid rotor construction — full cast iron for durability and reliable heat management
• Drum-in-hat (DIH) design — integrates parking brake drum within the rotor hat
• Non-directional swirl finish — ready to install without additional machining
• Corrosion-resistant coating on hat and edge — extends rotor service life and reduces rust formation
• 5-bolt mounting pattern — matches OE hardware configuration
• No ABS tone ring included
• Nominal thickness: 14mm | Discard thickness: 12.4mm | Overall height: 76.5mm

The Caliso BR901750-01 is sold individually and is designed to restore OE-level braking performance with a straightforward, bolt-on installation process.
