While looking over Bluepoof's instructions, I noticed my front brakes don't have the clip hers has. Nor can I find it in my manuals. What's up with this?
Nope, I got that clip, it's kind of important too!Page 6-46 of the shop manual shows a cotter pin, #13. Is that what you're talking about? I don't see another clip mentioned in her write up.
actually it is heat shield. stainless does not conduct heat as fast as steel used for pad backing or aluminum pistons or steel pistons (most are aluminum lately).Like I said, I wouldn't install any shims unless they came with the pads. 1/32" of stainless steel isn't much of a heat barrier.
They are sometimes called anti-squeal or anti-rattle shims.
anti squeal shim is rubber glued to back of pad or rubber plug put inside piston.As Andy says, they're a 'anti squeal' shim; they help to eliminate high frequency vibration that we hear as squeal. They work well on some vehicles, and less so on others.
