The disc brake system generates very high temperatures, especially when heavy braking is used when reducing speed quickly or descending steep hills.
For this reason behind the brake disc on each wheel there is a circular metal sheet roughly the same dimensions as the disc. The brake heat shields front is a circular fixed plate which functions to protect the rubber components of the velocity joints, steering and suspension parts situated behind the wheels from the intense heat that can radiate from the discs, which could damage the rubber.
Problems arising with the heat shields can be from corrosion or the shields having become misshapen through contact with stones or debris from the road causing the shield to rub against the disc.
Replacing this part with the brake heat shields front will ensure perfect compatibility with the make and model of your vehicle.
