Hi Dave,
Thanks for the feedback, and I’m glad to hear the braking performance is spot on.
With resin pads, a bit of noise in wet conditions can happen, especially when the pads are still quite new. At around 50 miles they may still be bedding into the rotor properly, and in the wet you can get a temporary squeal as water, grit and road film pass between the pad and rotor.
A few things to check:
Make sure the caliper is aligned correctly and the rotor is running clean through the pads.
Avoid using strong cleaners or bike wash directly on the braking surface, as this can interfere with the transfer layer on the rotor.
After washing or riding in heavy rain, do a few firm controlled stops to put some heat back into the pads and dry the system out.
The important part is that the pads are braking well, so it does not sound like a power issue. Wet-weather squeal is normally vibration rather than the pad itself being faulty, but keep an eye on it as they get a bit more use.
If it continues after a few more rides, send us a quick photo of the pads and rotor and we’ll take a look.
Kind regards,
Lee
