Re: Pads or Discs
Glazing is caused by heat on the pad face. Bedding in properly helps with this. Two schools of thought on this, either be really gentle with them for 100 miles, the other, and my preferred route is to find a bit of deserted road , get to about 60 or 70 mph, and hit the brakes hard to standstill, then repeat a few times, that will wear the brakes in nicely!
Glazing can come from poorly adjusted or sticking calipers. The pad should jump off the disc after use, if the sliding pins, or the sliders are sticking this won't happen. Lots of copper grease on the slides, the pins and anything that moves over something else (except the pad faces of course)
Check the brakes are all lubed up, the pads are freshly bedded in. You should be fine. Some Pads take a few months to stop squealing especially at low speeds, my Feredo DS Perfs took about 3 months to stop squealing altogether!
