Frozen and stripped brake line nuts prevent disassembly, with brackets and hoses also seized, making replacement impossible.

Existing tools like flare wrenches fail when nuts are corroded and stripped; no easy way to apply controlled heat or penetrating oil without damaging nearby components, and no specialized tool to grip stripped or rounded nuts in tight spaces.
