originally used the tangente platinum pro pads that came with the wheels - loved the feel of the pads, but squealing drove me to try the swissstop yellows. both types of pads tried flat and toed in (at various degrees of toe). swissstop yellows don't squeal as bad, but the feel is not nearly as good, and instead of squealing, i sometimes get a shuddering vibration on hard stops.
between each test I deglazed the pads with sandpaper, and cleaned the brake track of all pad residue. i tore the brake calipers down completely, and the mounting hardware, cleaned and lubed where appropriate, and reassembled, and still get the same problems.
I have not found anyone else running this setup and having any issues (and only one person running this combination setup in the first place), so it may just be something very specific to my machine.
i have scoured these internets and tried all sorts of crazy ideas:
- dry lube on the back of the brake pads
- duct tape on the back of the brake pads (haven't tested this one out, once the I get my stitches out from my knee - screw removal last week - i'll see if it works at all with either pad type)
I ordered a set of new sram red aerolink calipers to see how much of the issue is the brakes. My guess is that different calipers will make a difference, and if they do, I will have to decide between my lovely EE brakes and my lovely 303s. I don't want to give either of them up, but the squealing issue is distracting (and embarrassing on group rides).
Swisstop is coming out with the black prince carbon rim pads (any day), and I could also try the zipp tangente cork style pads, but don't want to keep throwing $75 sets of pads at the issue if I keep getting the same results.
any other suggestions are appreciated (or if you want to send me an old pair of your tangente cork pads that you don't need any more for me to try out)!
EDIT: I'm running tubulars
there is always a reasonable bet that I am overthinking things, but until I figure it out, it will gnaw at me like necrotizing fasciitis.
I also run the Zipp Tangente Platinum pads, no squealing whatsoever.
Sometimes they recommend putting a credit card on the back part of the pad, and adjusting them so they are toed in slightly to help with noise.
I just put them flat personally because I don't have these issues.
I'm wondering about your brakes also. Do you have another set to try. I'm running Sram Red brakes, and had Force previously...never had the noise.
I get my sutures out Friday, and will get to see how they act in the real world (the brakes/wheels, not the sutures).
they were helpful at least in confirming that i had done everything right in trying to fix the problem, and said they'd send me a set of the tangente cork pads to try out. the rep said he'd also check with the other folks there and see if they had any other suggestions.
they did ask if i had talked to the folks at cannondale about it, since it could be frame-related. i said i hadn't, since i couldn't think of anything useful cannondale could contribute, but i guess it is possible that it is a harmonic resonance that involves the frame. maybe i just need to drill a few strategically placed holes in the rear triangle
But otherwise the noise is energy leaving the wheel and is part of the braking, not ideal but it is tolerable.
