Anyone ever experience an unusual brake noise?

[BigMike54]

There is a loud metallic clank in the front brake that seems to suggest the pads are moving in the guide. It only occurs when initially moving forward after backing, or backing after moving forward. It’s like they move slightly and then set themselves. I had a very good local mechanic who could not find anything abnormal but theorized that the pads were shifting.

There is no Mazda bulletin on it. I will be replacing the pads and rotors soon but just curious if anyone has experience something similar.

I believe this is common. I have it on my 22 GT.

There is a TSB for it, but it only covers 2016-2020 (TSB). It's only temporary though.

I took the brakes apart and lubricated the guide plates this fall (annual cleaning anyways) and it was good for about a month or two before the noise came back.

Doesn't impact the brakes; just mildly annoying.

Thanks - that confirms what the mechanic said.
