Astra 53 plate

Hey folks, couple of questions about our Astra 53 plate.

When my bf brakes quite firmly in the car, there is a vibration through the steering wheel. We've had the tracking done, the wheels balanced, and the brake discs & pads seem to be ok when we got them checked.

When pressing in the clutch the engine makes a different noise - its a diesel but the noise is tinnier and louder when the clutch is in. You can only hear it inside the car - if you stand outside it makes no difference We've had a mechanic take a quick look at it but after checking all the obvious stuff he couldnt find anything.

Any suggestions?

The vibration may be due to the brake discs being warped - only needs to be a little to cause vibration. When braking is the vibration worse with the clutch down (neutral) or with the gears still engaged ? as this could be a DMF issue.

The noise when engaging the clutch may be the release bearing but as its a diesel it may be fitted with a Dual Mass Flywheel which could also be worn/faulty.

Thanks... the vibration is no worse when in neutral or with gears engaged if that helps?

I'd say when braking hard would be more to do with the discs if like you said other things have been checked and are ok.
