Applying a very small amount of brake grease to every metal-to-metal contact
points helps a great deal, but there are some pad materials that you just
cannot fix this way. Speaking of pad materials, some also deposit a black
dust on the front wheels that is very difficult to shift if it has gone
through a couple of heat/wet/cold/dry cycles - I have to use Autosol -
whereas others just seem to make the front wheels hardly any dirtier than
the back, it is a lighter colour, and it washes off with a hose brush.
