Brake caliper question
« on: January 10, 2015, 10:23:46 pm »
I have always done this without too much thought involved but it occurred to me I didn't really know why they were designed this way.  Each caliper has a guide pin and a lock pin.  One of which has a wide rubber O-ring on the end.  Why were they engineered this way?  I was just thinking the o-ring was to keep the caliper from sliding back and forth too quickly...

the "oring" or sleeve is there to act like a damper.  It helps kepe the metal separated and reduce vibrations and noise under braking (mainly squeal and harshness)

Yes, I can see how it would dampen some vibrations.  I have taken apart a few calipers where the pins had been installed in the wrong location but haven't noticed any problems with the "incorrect" installation.
