squealing firecrest 303s - any ideas i haven't tried yet?
Posted: Mon Sep 24, 2012 3:37 am
setup: new zipp 303 firecrest clinchers with EE brakes on my cannondale evo
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)!
TIA
