i have a 2005 grand scenic 1.9dci ,i have just taken it for mot and the car failed when the handbrake was being used on the rollers , it makes a squeeling sound on the drivers side rear the print out shows that this side is not working when engaged but the footbrake is fine, i have had the car to a local renault dealer recently and they said it just needed reset which they done and charged handsomely for it. but the problem is still there any sugestions please thanks.
