hello, i have a 1999 T cuore and the brake fluid seems to drop an inch or so in about a month. the brake fluid chamber is attched via a metal bracket to a round metal disc. this disc looks bubbled where the acid is presumably coming out. has anyone had this problem? will i need a new chamber or will the bracket not be fixed properly? i am a rubbish girl and do not want to be ripped off at a garage! thanks for any help anyone can provide.
