    Hello.
    OK so I just got hold of some Q5 4pot brembos, new brembo discs, and brembo pads, basically everything but a brembo air freshener to upgrade my Crappy A5 brakes.
    So basically, I am from an old school era of using copper slip on the back of my pads, yet while I googled out of curiosity if people still perform this practice, it seems it's 50/50 that this sort of thing is required.
    Which begs a debate I feel.
    Should I, or shouldn't I apply copper slip to my pads.
    Thanks in advance for your input...

    Did your boxter brakes work fine when lubed up Fred?
    No squeal?

    How about this for an answer; Yes...and No!
    To explain, I love copper ease and have used it on everything for years. I think the Internet is ruining it's reputation and unjustifiably so, but that said it's not the be all and end all. The reason I think this, I have discovered Brake grease, so what I do now is Brake grease on all the moving parts, it's a high temp grease so doesn't melt at higher temperatures and run off and a bit of copper ease on the back of the pads to prevent squeal. The problem with Copper ease as a lubricant or anywhere exposed is it picks up dirt and the more it builds up the heavier it gets then my thnking is it falls off in a lump, alternatively maybe when the brakes are getting hot it actually does run of because it's not High temperature. I have done brakes at any rate and maybe a couple of years later taken them apart for one reason or another and thought, where's the copper ease, it's a mystery but there is none left and I hate doing jobs twice. So this seems to be working for me anyway, hope it helps others too.

    Interesting and duly noted.
    I raised this thread partly out of curiosity as when dismantling my new calipers, they are more or less new with little use and discovered firstly a lack of copper grease, or any other lubricant for that matter on the set up, and secondly the most inner pads were bonded with a hot melt glue of some sort which I presume is to help against brake squeal.
    May be this is the future? Glueing pads to pistons, I have read about brake gum before but never realised manufacturers actually adopted it into production

    Some Audi pads, particularly rears come with a sticky backing, you peel of the grease-proof paper and stick them in, it may be the remnants of that you are seeing. Flat sticky surfaces adhere really well to rust...Not, so I don't raelly get it, more just ignore and fit anyway :)

    I know the type you are describing, but these were literally glued in, apparently S4 and S5 sliding calipers have this too, and you really have to prise them out.
    The glue is easy to peel off so no drama.
    I may consider that red stuff called brake disc quiet that dries to a rubber bond.
    I here good reports about it

    Mmm interesting, I haven't come across that, it's mainly older stuff I work on so obviously not filtered down to me yet. Another thing about Copper ease is there are different makes, original good quality stuff and a load of cheaper sound alike products. The cheaper ones are fine for some things but for the more important jobs I always keep a bit of the good stuff.

    I use copper grease or brake grease on the edges of the pads to stop them rattling or sticking. Usually new pads come with the sticky soft pads on the backs but they do wear through after a while.

    Engineer for EBC for 11 years. Was always a big debate but overall I would say the consensus was to stick a small smear on the back of the pad and the slide ways

    As above I use a small amount on the back of the pad and on the points of contact on the slide. It may or may not be needed but it does no harm and only takes seconds to put on. And saves having to take the pads back out and grease them if they do need it.
