• I have recently swapped out the front end of my commuter for a disc fork with a trp spyre. I have a shimano 180mm centerlock rotor.

    Originally I had the stock trp pads in there but I was experiencing some severe juddering. It felt like the pads were slipping against the rotor when squeezing heavily through the lever.

    I swapped out for some new shimano resin pads I had spare and the juddering issue went away.

    However, some new noises have appeared:

    • after braking when I hit a bump I can hear a click from the front
    • once that first click has appeared, I can hear another click when I very gently apply the brake

    I think both of these noises are due to pad movement? One thing to note is that the trp spyres come with a threaded bolt with a little clip on the end of it, while the shimano pads are secured with a split-pin.

    Is it likely that this is just down to pad movement? I was thinking to just swap to a split-pin and see if that holds them better. Any need for concern (front and only brake)?
