As the pads wear, once the seal has reached maximum twist, the piston slides through, but the untwisting will still retract the piston. This is how disc brakes self-adjust.

    These are special items so you're not going to find them at Mitre10. Considering what they do, and how important they are, they are cheap at the price.

    This man has explained it very clearly.

    Or don't. Who fucking cares about you anyway cheapskate?

    Yeah , I didn't think $200 was too bad for the right parts, but some folk don't understand the difference between cheap and value.

    Just get the Kwaka parts.
    I mentioned vegetables once, but I think I got away with it...........

    I find it concerning that someone so clearly clueless would consider pulling their brakes apart themselves.

    Get someone who knows what they're doing to do it.

    LOL.

    Ended up going with www.partsmonster.co.nz so far emails are being responded to very quickly and they were the cheapest I could find. Pretty much as soon as I realized that they are not just straight stock standard o-rings but specialist parts I felt far better about the price. As long as you know exactly which bits you need to do a particular job the online microfiche is pretty fantastic.

    First time I've gone "all online" for bike parts and accessories (picked up some oil, brake fluid etc too) so we shall see.

    I once got some exotic tropical fish by courier post (within NZ of course) and they were fine, lived long happy lives.

    Not all o-rings, or in some cases square-rings are the same, different materials and in a lot of cases odd sizes to suit a specific application, so you have no choice but to buy OEM.
