Had an advisory on my MOT about EPB just passing. Seems it wasn't that good on the passenger side. That was a few months ago. Since then I've noticed a squealing sound coming from the rear wheel on that side when I drive forward atg first starting off. It doesn't make the sound when I reverse. After a reasonable journey the sound seems to disappear but next time I use the car it's there again for a while. Could it simply be rust catching that gets work off or possibly handbrake shoe connected? Any thoughts?
