How to use

Use the needle to guide, align, or temporarily support internal hose components during insertion, connection, or service of hydraulic brake lines. Ensure the brake system is depressurised and the wheel is secured before beginning work. Insert the needle carefully into the hose or fitting to achieve the desired alignment, then proceed with seating the insert or connecting the fitting. Remove the needle before final sealing and pressurising the system. Follow manufacturer instructions for FORMULA brake systems when performing any repair or replacement.

Usage recommendations

Wear appropriate safety equipment and follow workshop best practices. Inspect the needle for damage before use, discard any bent or deformed items, and keep spare needles in the pack to maintain workflow during multiple repairs.
