S Type DSC light

Just thought i would share my experience concerning my rear brakes and DSC light on my 3 litre S Type.

My rear brakes became very noisy under hard braking and when checked at the garage the pads were worn right down and one caliper was sticking.

New pads were fitted and caliper unjammed.However the road test found another problem,the sticky caliper was still sticking a bit and because of the new pad thickness the the brake got very hot,the car vibrated at high speed,then the DSC light came on, and then other brake got vey hot.The DSC light would come on after about 2 miles or when the brakes got hot.The dilema then..were the hot brakes causing the DSC light to come on or was the DSC faulty and applying the brakes causing them to overheat?

I bit the bullet and had two new calipers fitted and road tested it for a while with DSC turned off,Brakes stayed normal temp even after hard use.Then turned DSC back on and bingo, no light comes on,no overheat and no vibration.

So yes a caliper was sticking causing the brake to overheat but also because of that the DSC system was trying to compensate for the unstability on the overheating side by applying the brake on the other side.!!!hence the DSC light and hot brakes.

So problem solved and no fault with the DSC system after all, indeed quite the contrary.So dont automtically assume DSC fault if light comes on its worth checking the brakes first.
