Thanks… I have a good set of punch tools and a 32oz hammer. The fact that the pin’s head is flattened indicates it isn’t budging. My theory is the ring on the one side most likely fused with the Caliper inner hole body and on the pin itself. This is the first brake job on my 2015 , brake dust, salt, snow, dirt, water over the years.
If mechanical force can’t dislodge it, then it’s heat, spray, hit… I am sure that’s what the mechanic will do. Unless by that time the penetrating oil does it’s magic & they pop out
PS: my theory seems to be correct, our friends at
MB also have the same issue with these guide pins.
