All of the guide pins have a boot to keep out water and debris. On the R51 rear brakes, the top guide pen is all metal and the bottom pin has a recess for the rubber bushing. The bushing is used as an anti-rattle device.00pathySE wrote:Does that pin boot go on the top or bottom? What's the point of that rubber bushing anyway and why only on the one pin?
