160 mm Brake Disc for Dualtron Thunder/Ultra for Dualtron Storm Limited

160 mm Brake Disc for Dualtron Thunder/Ultra for Dualtron Storm Limited

This replacement brake disc, with a diameter of 160 mm, is designed for specific Dualtron electric scooter models, including the Dualtron Thunder, Dualtron Ultra, and Dualtron Storm Limited. It serves as a direct replacement for a worn, warped, or damaged original disc, ensuring consistent braking performance and safety.

Key Features and Benefits

• Exact Fit: Specifically sized at 160 mm for the listed Dualtron models to ensure proper caliper alignment and brake pad contact.
• Reliable Braking: A new, true brake disc helps eliminate pulsation, rubbing, and uneven braking, restoring predictable stopping power.
• Ventilated Design: Features a pattern of drilled holes and cut-outs across the braking surface, visible in the product images, which aids in heat dissipation and helps clear water and debris.
• Lightweight: Weighs approximately 123g, as indicated in the product images, contributing to minimal unsprung weight.

When to Replace Your Brake Disc

Replacement is recommended if you experience any of the following:

• Pulsation or vibration felt through the brake lever during braking.
• Visible damage to the braking surface, such as deep grooves, cracks, or severe discoloration from overheating.
• Uneven wear across the disc surface or if the disc is visibly warped.
• Damage to the mounting points or noticeable play in the disc.
• If the disc thickness falls below the manufacturer's recommended minimum limit (please consult your scooter's manual for specific values).

Compatibility and Installation Checks

Before ordering, it is crucial to verify the specifications of your existing brake disc against this product:

• Diameter: Confirm your current disc is 160 mm.
• Mounting Pattern: Carefully compare the number and arrangement of the mounting holes. This disc features a 6-bolt mounting pattern with a 50 mm bolt circle diameter (BCD) and a 25 mm inner diameter, as shown in the dimension infographic.
• Disc Thickness: While not explicitly stated, ensure the thickness matches your original disc to prevent caliper interference or insufficient pad contact.
• Offset: Check if your current disc has any offset from the mounting hub. Variations in hub, caliper, or spacers between different production years or versions of the same scooter model can affect compatibility.

Installation of brake components should ideally be performed by a qualified service technician. Ensure all mounting bolts are tightened evenly to the manufacturer's specified torque values (refer to your scooter's service manual). After installation, the brake caliper must be precisely centered over the disc. It is also advisable to inspect and replace brake pads if they are heavily worn or contaminated, as old pads can quickly damage a new disc.

Bedding-In Procedure

After installing a new brake disc, a proper bedding-in procedure is essential for optimal performance and longevity. This involves a series of gradual braking actions to allow the brake pads to conform to the new disc surface. Avoid hard, prolonged braking immediately after installation. Instead, perform several moderate stops from increasing speeds, allowing the brakes to cool between each stop, until consistent braking feel is achieved.
