Over the past few weeks the handbrake has been making a loud creaking noise when applied. It's almost like the sound of too much tension in a spring and the noise seems to be coming from just under the plastic cover. It has made this noise in the past but not all the time. It has been much worse since it had a new brake pipe fitted to get though it's MOT. Think it was the rear pipe so could it have been something the garage has done?? What the hell is that noise all about??
