Could my brake noise be because front pad shims are in upside down.

I've been addressing my new toe '72's issues one at a time, starting with brakes.

First job was a new reman brake booster from MSA which made a huge difference.

Second was to address break noise that occurred with slight pressure. Took off the wheels, pulled pads and shims, cleaned them up applied grase between the pad and shim, put them back the way I found them ( lots of pad left). Theth were much better but they still would "sing" a little with light pressure. Did a search and stumbled across a diagram that shows y shims are upside down.

The were and are in in an "L" shaped position with the arrow on the shim pointing down. Could this be causing my continued noise?:tapemouth

I do know the shims make a difference. I thought the arrow pointed in the direction of rotation. Which appears to be up.

The arrows should be pointing in the direction of forward wheel rotation, and I've also found from experience that they do matter.

I had an intermittend brake squeal and when I pulled my pads, I found my PO had installed those shims backwards. I flipped them around and my squeal hasn't come back since. I was thrilled it was that simple.

Took half an our this evening to jack up the car, place the jack stands, wheels off, shims switched and flipped with the arrow pointed the right directions.

Half hour test drive with lots of stop and go with no noise! Very pleased with easy fixes. Much more confident with my brakes.

thanks!

Excellent. Sounds like you an I had the same issue...

We needed to turn our squeal shims into anti-squeal shims.
