I still haven’t replaced my pads yet but I’ve pulled the pins and the springs to inspect and clean.
My rotors are still looking very good and I prefer to keep them untouched since there’s no pulsating at all. This is my philosophy on brakes but I’m not recommending for anyone else. When I bought OEM pads I also bought OEM shims. I did buy aftermarket pins and springs but those can be quickly replace if I’m not satisfied.
Edit: I just did my 2015 RAV4 brakes. The pads wore down nice and evenly to about 2mm. The clips and hardware were really like new. Still had some original silicone grease on the back of the shims. I did not use the new stuff I bought. Just pads.
Here are my part numbers if anyone needs them.
