Detailed Product Description

This Nugeon disc brake caliper is constructed from cast iron, providing strength and heat resistance necessary for effective braking.

Installation Notes and Tips

Ensure the brake system is properly bled after installation to remove air from the hydraulic lines. Verify that the bleeder screw is securely tightened and the banjo bolt is torqued to manufacturer specifications.
