  • On closer inspection I had very uneven wear on the old pads, possibly a stuck piston?

    Bike was new in late October, can't decide if it was a set up issue or if a piston seized over Christmas when the bike was sat for a couple of weeks. I will probably just resolve myself rather than involve the shop, but thoughts would be welcome.

    I have never seen a pad in that shape. looks like a faulty pad to me and that you lost your compound. I bet your rotor is fucked. If it's not, I'm mystified.

  • Interesting you say that as the compound "fell off" the other pad yesterday whilst I was investigating. I think the rotor is ok as it was immediately obvious whilst riding that something was wrong with the pad (i.e no more compound) and I was able to get home on the rear brake alone.

    Worth saying that the prospect of pad compound spontaneously falling off a cargo bike with child on the hills of Sheffield is somewhat terrifying.

  • We're they nonbranded pads or something? I'm only to use magura genuine pads from now on. Mainly because the non branded ones have thicker metal backing plates so are near impossible to fit without adapting them somehow.

    Would let wherever I bought it know about this.

  • Yup. Happens sometimes! Especially with cheap ebay pads and salty conditions. Superstar components had a terrible reputation for it ten years ago or whenever they started. Changed mftr or process slightly and now you only get very rare fails. Usually gravity/uplift day bikes on DH tracks that are being cooked then splashed through deep puddles on the track.

    IF it ever happens, just keep pumping the lever, brake will still function on the metal backing plate to a reasonable extent.
