When replacing the friction pads, is it only the two at the sides that need replaced or do you have to replace the one at the top as well?
I am wondering because if it is all three - why do they sell them separately? Do they wear at different rates?
I've never changed the front and back but I have checked them. With the sides, the last couple of years I have given them a rub with wet and dry paper and cleaned them with brake cleaner to remove the glaze. The hitch is still within tolerance and I haven't had any stability problems.
This was a much simpler job that I initially thought. Removed the two covers on either side and with a cross head screwdriver - popped the pads out. they looked ok until you compared them to the new ones...definitely showed signs of wear and certainly glazed. Put the new ones in and it was just push and click. Replaced the covers - new covers supplied with the pads and wow what a difference. I've cleaned the old ones by taking Doonass' advice, a light rub of wet very fine sandpaper will see them live on as spares.
