Did the annual oil change. Rotella 15w-40, plus a couple quarts of Lucas.
I also decided to try my hand at replacing brake pads for the first time, as I started to hear a little bit of a squeak coming from the front last week. Did some research and seemed like a pretty straightforward, simple job.
Ordered pads from Olethe, went with 80 series OEM vs. the thicker 100 series.
I removed the old pads and discovered that there were no shims present! Apparently the PO or whoever put these most recent brake pads in did not use shims. Everything I've read and seen online indicates there should be shims, and installing pads without shims is generally a bad idea. That being said, I also understand that the main purpose of the shims is to prevent noise (?). I've owned this rig for 4 and 1/2 years using the same brake pads, and never had any noise at all. I have no idea how long these pads have been installed before I owned the vehicle, but based on how much pad was left and the limited miles I've put on the vehicle, I would say probably quite some time.
I stopped my work and ordered a shim kit. If I'm going to do the job, I want to try and do it right. But my question for this group is this: if I'm getting zero noise without shims, are the shims truly necessary?
