Caliso BR53018 Rear Solid Drum-in-Hat Disc Brake Rotor

The Caliso BR53018 is a rear solid disc brake rotor featuring a drum-in-hat (DIH) design, where the parking brake drum is integrated directly into the rotor hat. This configuration is common on rear axles that use disc brakes for service braking and a drum-style parking brake, delivering a compact, OE-style replacement solution.

Engineered as a direct-fit OEM replacement, this rotor is precision-machined to meet strict dimensional tolerances for exact fitment with no modifications required. The non-directional swirl finish on the braking surface eliminates the need for machining prior to installation and promotes even, consistent brake pad bedding right out of the box.

Key Features:

• Solid rotor construction — engineered for rear axle applications
• Drum-in-hat (DIH) design — integrates parking brake drum into the rotor hat
• Non-directional swirl finish — ready to install without machining
• Precision-machined — tight dimensional tolerances for OE-style fit and function
• Outside diameter: 12.28 in. (312 mm)
• Nominal thickness: 0.55 in. (14 mm)
• Discard thickness: 0.49 in. (12.5 mm)
• 5-lug bolt pattern
• Cross-references: Raybestos 780152, OE# 4721240AC

This rotor is sold individually. Replace in axle pairs for balanced braking performance and even wear across both sides.
