Caliso BR900914-01 Front Vented Disc Brake Rotor

The Caliso BR900914-01 is a front vented disc brake rotor engineered as a direct-fit replacement for select Buick and Chevrolet passenger vehicles. Manufactured from full-cast gray iron to meet SAE J431 metallurgical standards, this rotor delivers consistent stopping power, structural integrity, and long service life.

The vented design features internal airflow channels that continuously circulate air through the rotor, drawing heat away from the braking surface during heavy use. This effective thermal management helps prevent brake fade and warping under demanding conditions.

Key Features:

• Vented rotor design for superior heat dissipation and reduced brake fade
• Full-cast gray iron construction for strength and durability
• Non-directional swirl finish on the braking surface eliminates pre-installation machining and promotes even brake pad bedding
• Conventional (non-drum-in-hat) rotor configuration
• Outside diameter: 11.65 in (296 mm)
• Nominal thickness: 1.18 in (30 mm)
• Discard thickness: 1.06 in (27 mm)
• Overall height: 2.01 in (51 mm)
• Center hole diameter: 2.66 in (67.5 mm)
• Bolt circle diameter: 4.72 in (120 mm) — 5-lug pattern
• Non-slotted, non-cross-drilled plain face design
• No ABS tone ring included

Designed for straightforward bolt-on installation, this replacement disc brake rotor restores OEM-level braking performance. Also sold under part numbers BR900914 and BR90091401.
