In inspecting the front brake pads, I found that one pad was severly worn compared to the other pad on the same caliper.
Obviously, the caliper was not self-centering itself on the Caliper Bracket.
I removed the single bolt (pin) that holds the Caliper onto the Bracket and found burnt rubber all over the bolt.
I pulled the Caliper the rest of the way off the other guide post (which is attached to the Bracket) and found that it was clean.
I presumed that the burnt rubber was gumming up the Caliper and not allowing it to slide on the Bracket.
I removed the Bracket as well and tried to clean everything up.
In doing so, I have found that the bolt (pin) has a smaller diameter than the hole in the bracket.
I have a picture attached, showing the diameter difference.
Is this normal, or should there be something else in there to keep the pin from moving vertically in the hole?
As a side note, the guide pin at the top had a rubber boot over it.
The guide bolt (pin) had the remains of a rubber boot over it.
Part of it was apparently melted to the Bolt (Pin) and in the hole.
Any advise would be appreciated.
