Caliper slide pin differences top and bottom, why ? and where they go?
I've seen this question asked over and over on different forums, always with unclear answers or no answers at all.
On a lot of different cars, the top and bottom slide pins are different, sometimes one of the 2 have a small rubber bushing installed in a groove at the tip of the pin, some other have stepped/tappered pin at the top or bottom, some cars have the same pin top and bottom...
My daily driver is a mk4 jetta. One of the pin is stepped (thinner at the tip) and the other pin straight in diameter with 3 ''flats'' in the pin lenght.
Looks like this: https://www.carid.com/images/wagner/items/h14925.jpg
Anyone has a clear answer on this issue? I'd like to know which pin goes where and why it's made like this... looks strange to me..
thanks a lot!
