sticky epb

[big kev]

hi to all , i was wondering if anyone could give me some advice on my handbrake . when my car has been parked overnight and i jump into it next morning the rear drivers side wheel gives off a faint squeel as i set off then when i brake for the first time it squeels loudly then it works fine thereafter it passed mot recently and examiner says brake not sticky or it would have failed test but im sure its sticking then frees off after some braking .
