I reckon not. From the Disc FAQ at the top.DGB said:I reckon that the pads are contaminated.
My brand new Hope's squeal when wet, my Elixir 5's squealed when wet, and the pads were not contaminated on either. I guess you can consider yourself lucky your's don't squeal when wet.The brake will squeal when wet.
they are unbearably loud and annoying. Happens with both light and hard braking. I am using metal pads, only ones i've ever used.frdfandc said:DGB, The OP stated that the noise ONLY HAPPENS WHEN WET. If it was a pad seating issue, then it would happen all the time.
My BB7's squeal when they get wet. My Juicy 7's squealed when wet. Shimanos squealed when wet. Most brakes will make noise when wet.
I never mentioned anything about a pad seating issue.frdfandc said:DGB, The OP stated that the noise ONLY HAPPENS WHEN WET. If it was a pad seating issue, then it would happen all the time.
Flame the pads and clean the rotors with IPA, see if that makes a difference. IME it will help.Slurry said:they are unbearably loud and annoying. Happens with both light and hard braking. I am using metal pads, only ones i've ever used.
From all the experience on this board when one of these threads pop up and the number of people that come out and say that is normal for disc brakes to make noise when wet. I would put it down to just luck.DGB said:From my friends and my own experience, our different brand brakes (Shimano included) don't make noise in the wet. I can't put that down to just luck.
Pad seating/bed the pads. Its the same thing.DGB said:You need to bed the pads in properly too to avoid noise and to increase longevity.
Wow, thats actually great news. I picked up four sets of those that a shop was clearing out, but I have yet to try them. They were $2 a set, so i had to get them.pinkrobe said:I had 775s with Shimano metallic pads for a while. The only time they didn't squeal was when they were wet. It was horrible on extended descents. I switched to Fibrax metal pads and the noise was gone, wet or dry. My SLX brakes have the organic pads, and they squeal a little when wet, but not much.
I dunno about that. While I've seen terms like bedding in or burning in or meshing or burnishing or mating to describe the pad/disc break-in process, to me seating is more about how the pad sits in the caliper...frdfandc said:Pad seating/bed the pads. Its the same thing.
