hi guys
my 2 has a loud squeaking noise coming from the rear wheel on braking a kind of tight spring noise
i'had this problem for 12 months now and i'm at the end of my tether s:( :( s:( , at last years service i asked them to take a look at my brakes they said my caliper was sticking and they had greased it , it did the trick for a couple of months then it came back same noise but louder, at this year service i asked them to change the offending caliper but they say my caliper isn't sticking and they don't know what it is s:? :? s:? .
any ideas on what it could be
thanks in advance
