Years ago, I had a "friend" change my brake pads and they have squealed and "ticked" ever since he did them. I am thinking all my parts did not get installed, let alone any anti squeal added to shims. I am gonna redo them now on my '98 LS400 but am not sure how I would know if pieces are missing. You know, shims, wear indicators, etc. Does anyone have a picture or diagram that will show me all the parts associated with my pads?
