I have just bled my juicy carbons, I noticed on the rear caliper that only one side is moving( right) the left is not moving at all! Could it be seized?
If so how do I repair it? Or do I just replace it?

Cheers

  • Why did you bleed them in the first place?

    Rubbing on disc, as a result of not fully retracting, front is now working perfect, rear is perfect on one side but the left does not fully retract or move for that matter, I have tried to move it manually but it ain't budging!

  • You bled it because it was rubbing?

    I bled my brakes because they weren't retracting which I thought meant there was air in the system

  • So what you're saying is that they are now just as they were before you bled them?

    I noticed whilst bleeding the rear caliper that it appears to be not moving

    Rub some brake fluid into the seal.

  • No you said it was rubbing as a result of it not retracting, then said you noticed it not retracting when bleeding.

    Thanks cooldad, will give that a go.
    Not moving at all, was obviously like that prior to bleeding.

    I had similar with an XT, I locked the moving piston off (I put a spanner through the gap in the caliper and wrapped string round to tie it hard on the caliper) then used the lever to 'force' the other out (A LITTLE), cleaned it, then pushed back, repeated until it moved freely.

    Chunkers is normally helpful so I suspect the influence of pop!
