This isn't that car specific so I think it can go in general.
Is it normal to get braking judder after having a 4 wheel alignment done ?
( brake discs are about 500 miles old )
On an E46 330D 2004, blackdiamoind grooved discs, textar pads.
Front tyres are Vred sessantas and around 9000 miles old and have a good 5ish mm tread left.
