'07 Cobalt LS, 60K miles.
Recently developed a 'rubber' squeal/squeak (as opposed to a 'metallic' one) when the brake pedal is depressed. Sound comes from under the dash. One URL [1] says to replace the brake fluid. (Doesn't say why.) Other threads talk about possibly a leaking master cylinder.
Any experience/info? Thanks.
