Detailed Product Description
The DuraGo BR55087 is a conventional, full cast disc brake rotor made from cast iron, providing a balance of durability and heat resistance. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and helping to maintain consistent stopping power. The rotor measures 11.69 inches in outside diameter and features a nominal thickness of 1.28 inches, with a discard thickness of 1.21 inches, indicating when replacement is necessary to maintain safe braking performance. The overall height is 2.04 inches, and it includes five mounting bolt holes arranged on a 4.65 inch bolt circle diameter, compatible with specific vehicle models.
This rotor is designed for use on various Buick, Chevrolet, Pontiac, and Saturn models, including the Allure, Grand Prix, LaCrosse, Montana, Relay, Terraza, and Uplander. It does not include an ABS tone ring and features a non-directional brake surface, allowing for flexible installation without concern for rotor orientation.
Common Applications and Issues Addressed
- Replacement for worn or warped rotors causing brake pulsation
- Restores braking performance on vehicles with reduced rotor thickness
