• Vented rotor design for improved cooling
• Drum-in-hat construction for integrated parking brake function
• Non-directional brake surface for versatile installation
• Five mounting bolt holes with a 120 mm bolt circle diameter
• Nominal thickness of 0.79 inches (20 mm) with discard thickness at 0.72 inches (18.4 mm)
• Overall diameter of 12.6 inches (320 mm) and height of 2.48 inches (63 mm)

Detailed Product Description

The DuraGo BR900734 disc brake rotor is constructed from full cast iron, providing a solid and durable braking surface. Its vented design helps dissipate heat more effectively during braking, reducing the risk of brake fade under normal driving conditions. The rotor features a drum-in-hat style, which integrates the parking brake drum into the rotor hat, eliminating the need for a separate drum brake assembly. This design is compatible with BMW 525i, 528i, and 530i models, ensuring proper fitment and function.

The rotor's non-directional braking surface allows for flexible installation without concern for rotor orientation. It includes five mounting bolt holes spaced on a 120 mm bolt circle diameter, matching the factory specifications for the listed BMW models. With a nominal thickness of 0.79 inches and a discard thickness of 0.72 inches, this rotor meets OEM standards for wear limits, ensuring safe and effective braking performance.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor surface wear
• Fixing noise or vibration issues related to rotor damage
• Upgrading to a vented rotor for improved heat management
• Restoring proper parking brake function with drum-in-hat design

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean mounting surfaces to prevent rotor runout
• Torque mounting bolts to manufacturer specifications
• Inspect brake pads and replace if worn to maintain optimal braking
• Check for ABS sensor clearance as this rotor does not include an ABS tone ring

Quality Assurance and Warranty

DuraGo manufactures the BR900734 rotor to meet or exceed OEM specifications for fit, form, and function. While this rotor does not feature a rust-resistant coating, its cast iron construction provides reliable durability under normal operating conditions. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
