Steering Shake when braking

[Khantouch]

The steering shakes when I apply the brakes at speeds over 40mph and above. It's fine when braking under 40. If feels as if the discs are warped. I have an AP set up fitted which has only covered approx 200 miles. However I have recently fitted a set of 12mm spacers all round. Any ideas or pointers as to what it could be?
All advice appreciated.

Does it do it without the spacers ?

The spacers have been on for approx 80 miles and was fine. It's just developed this recent but I'll try it without them to see if it's better

Did you bed the discs and pads in properly? And does the kit have the DS2500?
If you have still been braking hard those pads leave nasty deposits on the discs.

I has the same with new discs on the APs it was the discs bells so had to get them skimmed and balanced

Pad deposits with the factory 2500 type pads and APs is very common. Fitting RS29s is a great way of cleaning them up; they will usually sort themselves out very quickly.

Tell me about it.

Thanks Gents for the info, my apologies for not replying earlier due to working unsociable hours.
I purchased the kit from Martin (Track M3) and from what I can recall the kit came with 17mm Ferroda Pads. I use the car occasionally on weekends and have braked hard on a number of occasions when opening her up late a night.
I suspect the issue is a result of the brake residue a number of you have advised, what is the best way to rid of this.
Also in terms of bedding the brakes in properly, what should have I done or do?

Thanks

60 then slam on numerous times. If you do a google it will come up, there's more to it than 60, I think you build it up to 100. Get the discs blue.
