09D Replacement Brake Rotor Bobbin Spring Kit – Maintain Precision & Eliminate Play in Floating Brake Systems

The 09D Replacement Brake Rotor Bobbin Spring Kit is a complete hardware refresh kit designed for use with floating brake disc assemblies, specifically those using the 09D rotor and bell system. This kit contains all the essential wear-and-tear components required to maintain the integrity, performance, and reliability of your floating disc setup, ensuring tight tolerances, reduced vibration, and consistent braking feel.

Kit Contents & Fitment:

• Steel Bobbins – Located between the brake rotor and brake bell, these maintain the floating connection while allowing controlled movement under thermal expansion.
• Stainless Steel Sprung Washers – Fitted between the bobbins and the brake bell to control float, reduce noise, and maintain tension.
• High-Quality Fixing Bolts & Nuts– Heat-resistant and torque-stable fasteners designed to handle the high demands of performance braking systems.
• Direct replacement hardware kit for all ZERONINE Floating Disc Assemblies.

Key Benefits:

• Restores Precision Fitment – Replacing worn bobbins and springs eliminates unwanted disc rattle or float that can occur as components wear.
• Improves Brake Consistency – Maintains correct rotor alignment and movement for predictable pedal feel and braking performance, especially under high-temperature use.
• Reduces Vibration & Noise – Worn spring washers can lead to clattering or uneven disc movement—fresh hardware helps restore a quiet, smooth operation.
