    Default Copper greasing brake pads

    My brake have been squeeking ever since I had them changed a few months ago, and I've decided to try and sort it. I've gone through the How2 a million times, but just want to clarify a couple of things first before I get stranded without brakes.

    The How2 says to lightly coat thet back of the pads.. may sound a bit dumb, but which side is the back? The part which is touching the calipers, or the part which touches the discs??
    Also, Once the caliper is off, and everything sorted, does it go back on easily, or is there a special way of doing it? Winding tool etc? Or just straight clip back into place?

    Thanks guys

    ok should be fairly straight forward for you. The back of the pads refers to the side which makes contact with the caliper NOT THE DISC SIDE. Lightly smear the copper coating around the back with anything that touches the caliper. The calipers should slide back on because the distances would not have altered any. You only need to wind/push the pistons back if your fitting new pads which will be thicker than worn ones.

    The bit that DOESN'T touch the discs....

    Never done the Vec brakes but you will need something to compress the piston back in.

    The copper grease should go on the metal part the part the face that goes against the piston. NEVER put a lubricant onto the pads that touch the disc or the disc itself, ansd no it is not a daft question, you did the right thing, never be afraid to ask, there is always some one here that will help you.Mind you if you are not too sure how to c do your brakes, it might be a good idea to get someont to do them for you, or at least show you how to do them, brakes should always be done proporly.... hope I have been of some help.

    So important you said it 3 times

    Well it shouldn't be too hard as I'm just fixing the squeek, so should be same size putting back on as to when I took them off (unless I get hungry).

    I just had to double check, because it confuses me that to stop it squeeking you grease the back, but I'd always thought it was the friction of the disc that was squeeking against the pad. But I know that greasing the discs would cause me to not brake.

    Its the metal vibrating against the calipers and the end bits of metal which line up with the caliper carrier which causes it i believe. Also possibly caused by the amount of heat it generates too??
    I got a good squeal going on now with mine but hanging on till i get them changed!

    I've dealt with it for a few months, but its getting quite dangerous now.
    When I have the windows down and I can hear it a lot more, I try to adjust my braking pattern to minimise the squeak (usually by waiting till last minute and braking hard) and i've started to do it natuarally if I can hear it.

    Thanks for your advice guys. I'll let you know how it goes.
