Brake squeal on ceramic rims

I’m getting horrible brake squeal at the moment. I’m using mavic open pro ceramic with swissstop race pro green. http://www.wiggle.co.uk/swissstop-race-pro-green-high-performance-pads/
The pads are worn in (as bought 2nd hand) but have plenty of life left in them.
Was wondering if anyone had encountered the same problem with ceramic rims or could suggest a remedial treatment.. coating, cleaning, greasing :) for the rim. Failing that, can anyone suggest an appropriate pad for ceramic rims.
I have UTFS but didn’t find anything on ceramics specifically.

Cheers

try the following

citrus degreaser on the rim

correct pad alignment is crucial

if the brake pads have become shiny you can scuff them with emery paper or similar

+1 on the above.

Flatten any high spots - if the pads where slightly too low on the old rim you get the raised lower edge. Removing these improves brake feel and a possible cause of noise

Super. Thanks both.
Just to confirm.. is this appropriate? http://www.chainreactioncycles.com/Models.aspx?ModelID=5952

Rim squeal is caused by brake pad alignment. Toe your pads in so that the front of the pad is 1-2 mm closer to the rim than the rear and therefore hits the rim first. This should solve it.

a nail file or similar (taped to rim) under the trailing edge of the pad while you set them up gets just the right amount.

I have 2 pairs of open pro ceramics, one old on sachs hubs & one new on hope pro's, & I couriered for years on the old ones. So i've been using them for ten years. Started out on rubber pads & then switched to ceramic specific ones.

If you ever use standard rubber pads it basically lines the ceramic, leading to squealing & loss of breaking power in the wet. Use ceramic specific pads, dura-ace inserts are the only ones I've ever used. Can be found on the shelf in Condor. The ceramic pads are harder.

It will take some time to wear off the rubber on the rims.

Also you brought the wrong pad.

get swisstop blue.

scoble is right, the koolstop greens are ceramic, but not the swisstop greens

Hello,

I've got some new wheels with Open Pro CD rims.
Just wanted to check if these are the correct brake pads to fit? Calipers are pre-skeleton style Chorus Dual Pivots.

Any help appreciated.

Thanks,

Cd are not ceramic iirc

CD = a type of anodized coating AFAIK

use soft pads on them.

ah, yes it's been confusing me.

So just good quality pads - same as with aluminium rims?

I know the anodizing will wear down/rub eventually but any advice on how to keep it on for a while longer?

Thanks guys,
Kam

koolstop/swissstop pads.

end of.

Thanks Ed,

I'm being dim - Koolstop Green? Swisstop Blue? Or just the normal black ones?

Cheers

Remember what prancer just said about CD not being ceramic?

go for koolstop salmon.

Thanks fellas

Swiss Stop green are much, much better than Koolstop Salmon and, unlike Ed, I've used both.

Is this just improved braking, or will they also wear the CD finish less?

I used the Koolstop and the black swissstop.

The green were for high performance, does they last long?

are swissstop greens their soft compound?

i.e swisstop green is to koolstop salmon?

having a PITA job trying to find some bloody 105/ult/DA pad holders so I can use salmon cartridges, so bugger it and go swissstop might be easier.

Swiss Stop green are for aluminium rims, as are the black, but the green are marketed as 'high performance'.

I'm not prone to hyperbole, but, bang for buck, the green pads are the best upgrade you can make, the improvement in braking performance is amazing.

...so do you think that they wear the CD surface less?

Why do you care for the CD so much? It's gonna wear whatever you do, personally I would prefer it gone quicker if I was using it for a braking surface.

You could use cork pads to save your anodisation. This would make you a bit of a tart though.

I have stuck with Swissstop Greens on the road bike for the last 2 years. Expensive but impressive, especially in the wet, when you need them the most. Standard Shimano pads are very hard on rims in my experience. They seem to wear the rim almost as much as the pad during wet winter riding.
