Technical Specifications and Features

This disc brake rotor features a 295 mm outside diameter and a nominal thickness of 20 mm, with a discard thickness of 18.5 mm to indicate when replacement is necessary. The rotor is vented to allow air flow between the braking surfaces, reducing heat buildup during heavy braking. The directional drilled and slotted surface improves water and debris evacuation, enhancing braking performance in various conditions. The zinc silver hat finish and rust-resistant coating protect against corrosion, extending rotor life. It includes five bolt holes with a 13.3 mm diameter and a bolt circle diameter of 120.6 mm, matching the lug pattern of compatible vehicles.

Compatible Vehicles and Applications

• Chevrolet Blazer
• GMC Jimmy
• Isuzu Hombre
• Oldsmobile Bravada
• Chevrolet S10 and GMC Sonoma

This rotor is designed for use in disc brake systems on these models, providing consistent stopping power and improved heat management.

Common Issues Addressed by This Rotor

• Brake fade caused by excessive heat buildup
• Uneven brake pad wear due to poor rotor surface design
• Corrosion and rust on rotor surfaces reducing lifespan
• Reduced braking efficiency in wet or debris-prone environments
• Vibration or noise from warped or damaged rotors

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 18.5 mm before installation. Clean the rotor surface to remove any protective coatings or debris. Verify bolt hole alignment with the vehicle’s hub and torque lug nuts to manufacturer specifications. It is recommended to replace brake pads when installing new rotors to ensure optimal performance. Directional rotors must be installed with the correct rotation direction as indicated on the rotor surface.
