Put some medium grit sandpaper on a flat surface, rub each pad on that until the shine has been removed.

When you reassemble,make sure that the pads aren't dragging on the disk.  That seems to glaze the pads more quicky.

Seems to happen to me more often using modern pads

I think ( know ) I'll take that approach tomorrow and pray it works.  ;) Some people think I'm being cruel to my bike!    :o

Hi Ted
I'm not sure of the make , but they have always come from DSS.

exvalvesetdabbler:
The ones that I have are EBC and they still start to squeak a little after about 500ml   Previous ones were from DSS bought in the mid 90s squealed like a stuck pig.

I have the nylon ring still in there, makes no difference, just makes the braking effect a little more progressive.   What makes a difference is cleaning out all the corrosion in the groove that the seal occupies, not just gunk or bits of old seal, the corroded aluminum crust.  Failure to keep this groove clean makes the piston tight and it doesn't retract properly or enough.  With the front wheel off the ground it should spin easily with one finger with minimal rubbing sound of the pad on the disc.


Regards
Dave

Hhhmmm...remember the look on peoples faces in the scene in the film JAWS where Quint dragged his finger nails down the blackboard?  ;D
That's what people on the street around me look like sometimes when I brake!  ;D

florence:
For the last thirty years, mine has always squealed, different pads, various things, rubbed with emery, blah blah, always the same.  I am used to it, and feel comforted that something is happening down there.

I do not think it can be eliminated, just one of the many quirks.
