I needed to replace one of the shims on my wife's car due to it breaking. I ordered from Rockauto and received a set of 4 shims, 2 are silver and 2 are black. They are all identical. Does anyone have any idea if there is a specific order for these? In other words black on bottom, silver on top etc?

if they are identical probably not. the difference is probably paint/plated but for everything i deal with its usually plated for all of it, her current ones are probably all plated right?

They're plated but the little tension tabs somehow broke off which allows the shim to move side to side with the brake pads and contact the rotor so I'm changing all 4. It's strange because even on Ebay, if you look up any brake shims, most of them come like this with 2 black ones and 2 plated ones.

i would say position probably doesn't matter then, as for it breaking the pad probably got caught/too much friction and moved it but if the hardware moves completely with the pads thats super weird. then again im not familiar with alot of models yet. i know all our fieros, 90s ford trucks and s10s use a stationary pad shim/ brake hardware

So to make myself look REALLY stupid, here's the outcome. I ordered 3 bags of shims. Looking through the clear plastic bag, they all had 2 black and 2 silver shims in a bubble pack. I decided to open one pack to do the job and realized that they were silver on one side and had a black coating on the other. I guess I should have taken them out of the package BEFORE creating this thread.

So......if you order shims and 2 look black and 2 look silver, open the damn package and flip 2 of them over. Then they'll all match

I know I must have a seat on that bus.

What reason would one need a shim ? When a brake pad wears over time, do I need a bigger shim ?

Carter, yes the mystery is solved. I'm still an idiot
Cliff, here are the shims. They allow the brake pads to float with the caliper:


And Tedd, I guess I'll expect to see that bus in 4 days

I guess the way they're made, there's no real way you could install them backwards right? So the black side will always be outward facing?

Correct and as it turns out, the black coating is some sort of tacky material so that it won't vibrate in the caliper bracket.
