Hi Joseph. I use a Mavic 'pumice' stone to clean the braking surface on my Eurus rims. Seems to work. Also use it on the brake blocks themselves.
Derek, I have not heard before of cleaning the brakes. Would you provide more detail?
Heather, only really necessary if they do squeal. I usually drop the wheel out, roughen the brake pads with course sand paper and use a medium wet and dry on the wheel braking surface. Wipe all surfaces clean before reassembly. A damp rag will do. If squealing persists, it is probably time to change pads.
Sounds like such a first-world problem!
Sorry, just maybe a bit of jealousy there. :-)
Add a little bit of toe in so the shoes look like this in brackets > ( / \ ) My swisstops squeal when I brake hard but it generally when some nutcake driver pull out in front of me, the squeal acts as a horn in that case.
I changed pads ;) but agree with Alastair on their use as a warning device. I too was told to toe them in to assist stopping the squeal and to scrub the breaking surface clear of the yellow build up from the pads.
Also.... I managed to kill a back wheel using them which may or may not have started from a defect within the rim... don't know for sure but word from the wheel builder is that swiss tops have been cooking a few carbon rims of late as they tend to reflect heat back into the rim rather than absorb heat as a lot of other brake pads do....these are his words not mine. He provided me with some different pads after fixing the wheel at no cost...they were not branded. They don't break anywhere near as well as the swiss tops but they are quiet and hopefully will absorb a bit more of the heat that comes from the rims so as not to heat them up.
I have some swisstop shimano pads with not too many k's on them that you can have if you like...;) I won't be using them again.
My rear pads are still cork, they howled when first fitted but now they don't make a sound and work very well.
Happy to have my brakes sqeal, better than a bell. I was watching a doco on the 1962 Tour De France , and boy, did those bikes brakes sqeal decending the mountains.
The standard cure is to clean the brake blocks.
Check if they are shiny and sand them lightly until they are dull.
you usually only have to sand the rim unless brake performance is poor.
This is how you do it on low tec. bikes. (alloy rims)
Sounds like your wheels may have cost more than my bike so there may be a different way to work with exotic materials such as carbon fibre.
