Recently been noticing a sound like.. Thud thud thud thud thud when braking, worse when pressed heavily.. Discs and Pads were changed about 5 months ago (Drilled and Grooved discs and Mintex Pads) its definetly not coming from the rear its from the front.
What you guys reckon?

Does the steering wheel vibrate?

No mate, doesn't pull to any sides either. Although I grabbed the caliper from behind the wheel and could move it and you hear a knocking sound from the caliper should it even make a noise if you move it at all? The bolt that holds the caliper on is tight! Can't tighten it anymore

Do all the brakes lock?
You may get a little free play in the caliper when the piston returns slightly, but very little at the least.
Is the caliper carrier bolt loose?

Hmmm still worth a check as that's free but I would be inclined to say its close to normal but maybe a bit too much.
I want to say its down to the discs or hub face but since you dont having any steering wheel vibration under braking it shots that idea down

You don't get a thudding sound from drilled and grooved discs, you get a whirring sound when braking due to air going through.

Does it still rattle like that if someone presses the brake while you try and shake it like on the film?
Id be stripping them down and if thetes no improvement strip again and check whete your washets are placed then take some extra washers and put them in front of the bolt heads to be sure the bolts arent bottoming and you can get some clamping using the extra6-8mil of washers.....let us know?
