I am rebuilding my front calipers. They are the K-H type from a '84 GTI with vented rotors.
These have two guide pins (sliders) per caliper; a shorter one and a longer one. I want to replace them but I notice many vendors only list the longer guide pin for sale (see picture below). Looking at them, I see no reason why the longer ones couldn't be used for both sides on each caliper (i.e. four long ones instead of two long and two short). It will just stick out a bit at the exposed end. Seems like the rest of the hardware (plastic and rubber sleeves) will work the same regardless.
Anyone have more info on this?
Also, the old rubber sleeves that these guide pins ride in have deteriorated into a very sticky goo. What a huge mess it makes. Has anyone found a neat way to get all of that tar like slime off? It will eventually come clean but it is slow and a real pain to do.
