Pagid RS4-2s pad build up / vibration
rich83:
Dunno... would have thought about 950 maybe... speak to alex if you need a firm price.

Out in the car today.... same problem. I am wondering if wet and drying the discs would help
xjay1337:
I was going to do that but then I used Iron x and a stiff brush to clean the grooves which fixed it.
Annoyingly the problem comes and goes. It may be fine one day and then bad the next.
wet weather seems to cause more issues.

OK, to help...
What was your bed-in procedure? For a race pad, you need to be pretty much trying to kill them to get them to cure. You need to get them hot enough to 'burn out' the resin in the pad, looking at the cross section of a properly bedded pad, it should have at least half of it looking scorched.
If you haven't removed the resin, it'll just leach out every time they get hot and melt all over your disc causing vibrations. Some makes are worse than others, granted, but the same should apply for the same reason to any pad. You can remove this pickup with a garnet paper flapper wheel on a drill if you don't want to skim/regrind them. Don't use anything else, it'll knacker the disc.
Below is an image of someone bedding a pad on a dyno, you really do have to have them stupid hot, I used to have smoke billowing out of my brakes when bedding.
Latterly, were the pads of the right temp range for your car? Have you got readings from the brakes to know what range they operate in to select the right pad for your application?
In essence, the pads themselves were fine. Just maybe not the right choice for your car, and that's down to whoever recommended them or you not doing your research properly.
For the future, what level of cooling do you have? Ducting? Deflectors? Have you removed the stone shields?
