Detailed Product Description

This vented disc brake rotor features a 305 mm outside diameter and a nominal thickness of 29.2 mm, with a discard thickness of 27.5 mm to indicate when replacement is necessary. The rotor’s drilled and slotted surface enhances cooling and helps evacuate gases and dust generated during braking. The zinc black hat finish combined with a rust resistant coating extends the rotor’s service life by protecting against corrosion. The rotor is designed with six bolt holes, each 13.1 mm in diameter, arranged on a 127 mm bolt circle diameter, ensuring compatibility with specific Buick, Chevrolet, GMC, Isuzu, and Oldsmobile models including the Ascender, Bravada, Envoy, Rainier, and Trailblazer. The directional brake surface optimizes braking efficiency and performance.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Improves heat dissipation to reduce brake fade during heavy use
• Addresses corrosion issues with rust resistant coating
• Enhances braking performance on Buick Rainier and Chevrolet Trailblazer
• Suitable for vehicles experiencing reduced stopping power or noise

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 27.5 mm before installation. Clean the hub surface to prevent runout and ensure proper rotor seating. Use the correct torque specifications for the 6 lug bolts with 13.1 mm diameter holes on a 127 mm bolt circle. The directional surface requires installation in the correct rotation direction for optimal performance. Avoid contaminating the rotor surface with grease or oil during installation.
