Does anyone know for certain what the thread form is on the nipple connecting the brake line to the flex hose for a 2004 XLR?
I have a new Delco flex hose and it will not fit on the nut. I have bought a replacement nipple which states it is 10mm x 1mm and that will not fit into the new flex hose either. Measuring the new nut it is 10.4mm in diameter and has a thread form of very slightly more than 1mm. I am aware that manufacturers deliberately use a slightly incorrect thread pitch so as to create a locking effect, so it is 1mm effective. However, the new flex hose will not accept either the nut on the car or the new test one I have. Hence, what have Delco supplied? The flex hose is otherwise exactly correct, length, fittings at both ends.
As the flex hose Delco have supplied is a different thread size, does anyone know what it is intended for, eg a C5? (The part number is showing as correct, suggests a catalog error.)
TIA
