180 mm Brake Disc with 6 Holes for Electric Scooter or Bicycle

180 mm Brake Disc with 6 Holes for Electric Scooter or Bicycle

This 180 mm stainless steel brake disc is designed for use with electric scooters and bicycles. It features a 6-hole mounting pattern, making it suitable for a wide range of standard hydraulic or mechanical disc brake systems.

Key Features and Advantages

• Diameter: 180 mm, providing a larger braking surface compared to smaller discs.
• Material: Constructed from stainless steel for durability and consistent braking performance.
• Mounting: Equipped with a standard 6-hole bolt pattern for secure attachment to your wheel hub.
• Weight: The disc has a net weight of 164.2 g.
• Thickness: The braking surface thickness is 1.7 mm.
• Bolt Circle Diameter (PCD): The distance between opposite bolt holes (center to center) is 44.5 mm.
• Inner Diameter: The central mounting hole has an inner diameter of 22.5 mm.

Compatibility and Installation

This brake disc is compatible with electric scooters and bicycles that use a 6-hole mounting system and can accommodate a 180 mm disc. Before purchasing, please verify the following:

• Current Disc Size: Measure the diameter of your existing brake disc to ensure a 180 mm disc is appropriate.
• Caliper Clearance: Confirm that your brake caliper and frame/fork have sufficient clearance for a 180 mm disc. If upgrading from a smaller disc (e.g., 160 mm), an appropriate adapter for your brake caliper may be required to reposition it correctly for the larger disc.
• Mounting Pattern: Ensure your wheel hub uses a 6-hole bolt pattern with a 44.5 mm PCD.
• Inner Diameter: Check that the central mounting point on your hub is compatible with the 22.5 mm inner diameter of this disc.

Six mounting screws are included with the disc for installation.

Maintenance and Safety

Regular inspection of your brake disc is crucial for safe operation. Check for signs of wear, such as scoring, warping, or thinning of the braking surface. Contamination from oil, grease, or other substances can severely reduce braking effectiveness; keep the disc clean. After installation, new brake discs and pads require a "bedding-in" period to achieve optimal performance. During this period, perform several moderate stops from increasing speeds to allow the brake pads to conform to the disc surface.
