Brake Antilock Control Unit/module problems of the 2003 Land Rover Discovery Ii

Anti lock brake failure; multiple lights illuminte whe heavy braking down hills. All brake pads and rotors are new. Lights on dash extinguish upon restart. Very poor braking almost allowing vehicle to travel into cross traffic. Felt as though anti-lock system stopped functioning with standard braking remaining. Happended several times with myself and wife driving vehicle. Brought to dealer and looked up info on internet. Dealer indicated is was the antilock brake system modulator. Many complaints on rover websites about this going fairly early in life of vehicle. Dealership told my wife that there was still normal braking if lights are on,but it should not be used like your braking with antilock systems. I do not believe that landrover has not addressed this issue. This problem as caused several close calls when braking on limited hills. Dealership indicated part was $1500 and total job was $2100 to replace, but again said it was not necessary to do as braking would be there if lights were not on.

I have a 2003 Discovery Ii and the abs modulator is having problems with three main lights illuminating constantly and they are traction control, abs and hill descent control, when the lights illuminate in amber color while I'm driving I have no use of traction control and abs also my brakes don't work well.
