This thread again: Well not long after I said I'd cured it, the rear started squeaking again plus brake performance was just getting a bit shoot recently, like, will I stop at the end of this hill, shoot?
So I bought some Superstar resin pads and fitted them. So far, so bloody brilliant. Braking performance is so good I have to be careful not to lock the front wheel now. I shall see how this goes longer term but these pads are dramatically better than the two or three different makes I've used. I'd reached the stage where I was thinking of changing rotors and if that didn't work, upgrading the brakes. No need now. There also seems to be more feel and I note the Superstar pad spring is quite differently shaped to others I've used.
