Greasing brake pads and pins is something I've always done based on received wisdom that it prevent seizure and squeeling.... but is it REALY necessary on modern(ish) braking systems? Maybe I'll run mine dry for a while and see if it makes any difference.To be honest, I am not sure that he does know his stuff. I suspect that what he really, really likes is the sound of his own voice. I saw him in another video on Gearboxes that was just as long and almost as tedious where while the facts he used were not technically incorrect, he used them to imply something that was simply and verifiably wrong. In this case, after seven minutes of talking about sintering (which should have taken him 30 seconds) I gave up so I never got to hear his advice on copaslip.
Is it really necessary? No, of course not. Does it help? Yes it bloody well does. Ask anyone who forgot to copaslip their retaining pin and later had difficulty removing it. The difficulty comes from a build up of crap and corrosion that forms a solid seal. Do you want that same corrosion sealing your pads to your pistons? Preventing freedom of movement and probably affecting heat transfer? I don't, so even though I don't 'need' to, I will continue to use copaslip every time I service my brakes or change my pads.
