    Hi,

    I am trying to change the rear brake pads on a Movano 2004 but i am having trouble winding the caliper back. I managed to do one but the second just does not want to go back in. The one that i have managed needed to be wound anti clockwise... am i right in saying that that is the case for both sides? The one that just does not want to wind back in will rotate just not move back in.

    My questions are:

    1. To rewind the calipers do they both rewind anticlockwise?
    2. If a caliper does not want to rewind does that mean i need a new caliper?

    Thanks

    Nope! One is anticlockwise, t'other is clockwise otherwise it will wind itself in as you are driving!!I take it that it's the n/s caliper that won't screw back in? This one should be screwed in clockwise. The o/s is anticlockwise. They can be a bit of a tw*t to do, but a bit of good old WD n a lot of cursing and you should fettle it!

    I always use a G-clamp on any brake caliper pistons...works a treat.

    So do I but it won't work on a windback caliper as they self adjust the hand brake and wind out as the pads wear down.

    If the calipers aren't wound back there won't be enough space for the disk to fit.

    Nope, still works for me. If the calipers are wound in clockwise just the action of twisting the thread on the clamp will wind it in, if not, give it a little help with a pair of swan-necks and a rag to stop any damage to the piston.

    Not sure how it can work

    G clamps have a ball or slip joint on the end of the screw and therefore very significant pressure needs to be applied before that joint would bind and that would pressure would cause a bind on the caliper piston thread.

    Beside how would you deal with calipers where one is clockwise and one anticlockwise?

    I'm just bloody good at it I guess. The ball and socket on my G-clamps seem to bind quite quickly and they wind in a treat. As for anti-clockwise I use the swan-necks and G-clamp and with a little jigging and poking, in they go. My three years at college gave me the theory and ten years on the job as a volvo technician meant that winding in brake calipers is now second nature.

    Most of the calipers I encounter don't want to wind even with the right tool.

    I can't help thinking that you are just making it hard for yourself.

    Why not just use a rewind tool?

    I'm not in the trade anymore and spending out on tools when my g-clamps work great would be a bit silly. I really don't find it at all difficult to wind in brake caliper pistons! Maybe I'm just lucky.
