Squeaking brakes

[Thunder]

Been having this problem for a while then it goes away and comes back again.
Every time I step on the brakes it has this horrible squeaking noise.
Is there a way to clean or lube them so that they don`t squeak anymore?

I think only way is to keep taking off..cleaning..and copper slipping..then just get lazy and forget about it.. :dunno: ..never had a prob on my e36 with ferodo and a good amount of copper slip..itl be interesting to know if there is something you can do to permanently stop it

Where would I be able to get copper slip from?

I've seen it at Midas and Autozone. It might be called "copper grease", "anti-seize compound" or something like that.
