I have a Vauxhall zafira which I bought a year ago. I was told upon buying the vehicle that its pads and discs would need replacing soon so I changed them straight away (with genuine Vauxhall ones, not cheap ones).
Unfortunately there is always a horrible grinding type sound when I come to a stop, using my clutch. This only happens once the car has warmed up (not first thing in the morning). The brakes seem to be performing well, so I have no concerns there, however my mechanic has confirmed that the noise has nothing to do with the brakes, and is actually the flywheel making that sound, something to do with the grease? He's told me that it's nothing to worry about, and that changing the flywheel would be expensive and unnecessary. His conclusion was to just put up with the noise as it is nothing serious, but I am still worrying. Does anybody understand what the problem could be and if it is serious or not? My mechanic is a trusted friend, however my head is telling me not to ignore the noise.
