Ryan,
What docwra has said ^^^^
But you already know that as I have spent considerable time answering your PMs, which you appear to have ignored.
Copy of my last PM below:
Ryan,
I am basing my reply on that you have also replaced the discs.
Firstly, I am assuming that you do not have a slight wheel balance issue at 70mph and that the brake application is not highlighting the vibes.
I am aware what it states on the box but I have fitted hundreds of DS2500 pads to road cars and had no issues, except some complaints about brake dust.
When fitting new brake discs, then all faces including the hub, both sides of the disc and the inside face of the wheel must be spotless and true. If this is not meticulously carried out then DTV will develop causing brake vibrations.
No amount of bedding in will cure DTV.
If all the above is good then I would bed in again, see guide below.
Regarding brake squeal, again the caliper housing which holds the pads must be spotless.
The pistons must all be free and the upper and lower sliders must be in good shape.
Anti-squeal shims must be fitted to all pads.
Finally, a good quality anti-squeal copa slip greaze must be applied to the rear of the pads.
As I said previously, this is certainly a fitment issue.
