Brake judder

Judith Chambers said:

I have a 2013 Discovery 4 , that has in the past year had discs and 2 sets of pads replaced because of brake judder .
This mainly happens when traveling at speed but can almost be any time.
I use a very reputable LR dealer and they are genuine LR parts.
Any suggestions welcomed.
