Are brake shims required, recommended, or not needed?
I just bought some Project MU NS brake pads for the front and rear, and I hear they do not come with shims. I currently do not have any spare shims that are in good condition and was wondering few things.
1. Do I need shims? If I just use some anti-squeal stuff would that be good enough? Are shims used for another purpose besides stopping noise?
2. If shims are recommended, is there any place to buy them without having the buy the whole *hardware kit* that cost between $30 and $40 each?
3. Why don't these pads come with shims?
Thanks for any answers

I doubt it matters ---I use the spray for other things too ---Elec connections,Battery Terminals, even as a sealent for example on a plenum gasket ----The spray is kinda handy ----I even spray it on a socket and let it tack up so I dont drop a bolt Im trying to get into a tight spot

The whole problem with using the stock shims is i dont have them, and they cost $30-$40 to purchase.... I guess I will try the pads without shims (unless someone explains why i shouldn't) and if they squeal I will purchase shims....

If your pads come from a reputable source, then if it needs shims they will supply them. This is to cover their *** also, why take a chance on customer complaints over 4 cents worth of sheet metal ?

Also ---many times the "shim" is adhered to the pad and over time/heat separates it, so when u take off the pad , there is a separate shim that was once part of the used pad-------Throw it away just like u do with the pad

I will go on to say ---I get pads with a "shim' as part of the pad, I get pads that have "shims" with peel off backs that you stick to the pad and I get pads with no "shims" I install them accordingly but always use Anti-Squeal spray

The shim is there not only for noise but to protect the piston and the pab from wearing into each other. If you brakes are designed without a shim, than you don't need one, if it is and you don't use one - you will have to replace the pistons sooner or later.

Oem shims are TUNED to match [reduce] the noise from oem pads..........aftermarkets don't want to spend the millions necessary in testing to develop a matching shim.
