DuraGo BR34140 Disc Brake Rotor - Front

Overview of DuraGo BR34140 Disc Brake Rotor

The DuraGo BR34140 is a vented disc brake rotor designed for reliable braking performance on select Saab and Saturn vehicles. Engineered from full cast iron construction, this rotor offers consistent durability and heat dissipation for everyday driving conditions.

• Material: Cast iron for strength and heat resistance
• Vented rotor design to improve cooling
• Nominal thickness: 0.98 inches (25 mm)
• Discard thickness: 0.87 inches (22 mm)
• Outside diameter: 11.34 inches (288 mm)
• Mounting bolt hole quantity: 5 with 0.56 inch (14.2 mm) diameter
• Non-directional brake surface for versatile installation
• Conventional rotor type without ABS tone ring

Detailed Product Description

The DuraGo BR34140 disc brake rotor is constructed from full cast iron, providing a solid and durable braking surface suitable for Saab 9-3, 9-5, and 900 models, as well as Saturn L100, L200, L300, LS series, and LW series vehicles. Its vented design enhances heat dissipation during braking, reducing the risk of brake fade under normal driving conditions. With a nominal thickness of 0.98 inches and a discard thickness of 0.87 inches, this rotor maintains optimal performance until wear limits are reached. The rotor features a 5-bolt mounting pattern with a 4.33 inch (110 mm) bolt circle diameter, ensuring proper fitment on compatible vehicles. The non-directional brake surface allows for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

This rotor is compatible with the following makes and models:

• Saab 9-3, 9-5, and 900
• Saturn L100, L200, L300
• Saturn LS, LS1, LS2
• Saturn LW1, LW2, LW200, LW300

It is designed for use in conventional braking systems without ABS tone rings and is suitable for drivers seeking a reliable replacement rotor for routine maintenance or repair.

Common Issues Addressed by DuraGo BR34140

• Brake rotor warping causing vibration during braking
• Excessive rotor wear reducing braking efficiency
• Overheating and brake fade from insufficient cooling
• Corrosion-related rotor surface degradation (note: no rust-resistant coating)
• Uneven brake pad wear due to rotor surface irregularities

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (0.87 inches) before installation
• Clean mounting surface to prevent rotor runout
• Torque mounting bolts to manufacturer specifications
• Check compatibility with vehicle’s brake system and wheel hub
• Replace brake pads when installing new rotors for optimal performance

Quality Assurance and Warranty

DuraGo manufactures the BR34140 rotor to meet industry standards for material quality and dimensional accuracy. While this rotor does not include a rust-resistant coating, its full cast iron construction provides reliable structural integrity. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
