Good evening Gents/Ladies.

Very new here and this is my first topic post.

I have recently purchased a Overfinch late 2008 tdv8, it's already been given a new torque converter since I have owned it
So on Friday I decided to give the old girl new brembo brakes (front disks + pads)
Friday afternoon I collect the car and begin my drive into London and come to a stop at speed on the M25 70 down to about 40
It was hard not to notice the almighty banging / knocking that was coming from the front. I can feel it on the brake pedal , steering wheel and could hear it. Made a phone call to my garage and said WTF I continued my journey with caution. It was up till I reached a housing estate with bumps and sleeping policemen that the problem almost stopped. Then it became more of a defined knocking noise when applying the brakes with average pressure. If the brakes were applied with good pressure or slight pressure it wouldn't be as bad.
After doing some reading the knocking maybe constant with lower arm bushes. But the problem wasn't there before I had the disks and pads fitted Friday morning ???

Anyway if there is anyone with ideas i would gratefully appreciate the advice.
It's going back to garage tommorow afternoon so fingers crossed

This has been resolved , I bought another new set of disks and the problem disappeared.
Very strange that new brembo disks would give me trouble
