So, I have determined that there are in fact 3 designs of parking brake, the JNC (push to release) and the 1st design and the 2nd design. Mine is not JNC so is it 1st or 2nd? After checking with my dealer and suppliers, I was unable to determine by vin however, the suppliers provide a vital clue. Along with the cable (length left or right) they also specify the length of the intermediate cable that it goes with. In my case, the intermediate is 1545mm (60 5/8”) and as such is the “1st“ design and therefore the right brake cable for mine is the 100 3/4 which is GM 25864664. I wrongly ordered the 2nd design 109” cable and discovered that the jackets are identical on both (87”) however the overall length of the cable is 8 1/4” too long. I presume that difference is all at the forward end of the cable as the wheel ends on both look the same (same spring). Some pics hopefully clarify for my XL, 60 5/8” for the intermediate and 87” jacket (not shown) + 4” at wheel + 9“ at forward end for approx 101”. First 2 photos shows me measuring intermediate and then the cable lengths protruding from jacket on the wheel and forward ends of the right side cable.
She works great now however I discovered I need new rear pads, thats next weekend
Thx for the input folks, hope this helps to clarify the situation for others.
