Squeaky brakes

Icy J · 05-26-2015, 08:17 PM

Is it normal for the brakes to be squeaking and squealing when not warmed up? I only figure it has something to do with temperature as it's more pronounced during winter, and disappears during/after 'spirited' driving. I have the M Sport brakes, if that's relevant.

I think it could be one of two issues. First, sometimes a fine film of rust can cover the rotors after it rains or it is very humid and you may need to apply the brakes a few times for it to clear, causing the noise. Second, I'm not sure, but if the M sport brakes come with a more aggressive pad, they certainly can squeal when they are cold. When they come up to operating temperature, the squeal goes away (happens to me when I'm at the track with aftermarket pads - that's why I change them to the stock ones before going home - too noisy).

I get it too but does go away after 10 mins. The msport brakes are definitely aggressive as hell

Ah okay, thanks. Probably a combination of both TBH, annoying but guess it's normal lol
