Just serviced the pilot brakes for the first time. Noticed that the
inner pad wore faster that outer on passenger's side. Tried to take
out sliding pins. One came out easily. The one with a rubber ring at
the tip took quite some force. It would appear that the rubber ring
has swollen for some reason and it seals the sliding pin hole with
force. Not sure why it did that since the lubrican is the original
from factory (This is my first brake service). I could file down the
rubber, to make it fit more loose, or I could take if off permanently.
Does anyone know what is its purpose?
