Hello I am very proficient with repairs on my other Volvos but this V 50 gives me fits. I am attempting to remove the 2 7mm allen head brake bracket bolts which are located under the dust cap . I loosend these completly but they are still not completly disengaged do they need to be tapped back so that the bracket can be removed, In the past these bolts where just slide out on my other volvos. Thanks
