This upper WRC R component serves as a replacement part in the brake system of selected Citroën vehicles, including older passenger cars and vans. The unit supports proper operation of the brake hydraulics and contributes to stable brake response. Its design follows original Citroën specifications for pressure behaviour and fit. The part connects to brake lines with an inch size port. The construction allows installation in existing systems without changes to the main surrounding components. The chosen material supports long service life under normal mechanical and thermal loads present during regular vehicle operation.
