Just got the 'Check Brake Linings' message come up in the Check Control display so i reckon some or all of my brake pads need replacing (and the sensor I guess). Well they do say it comes in three's - battery getting a bit weak, airbag light on & now brake pads - merry christmas

As this is my first 4x4 I'm unsure if the braking bias etc. is different to 2 wheel drive cars so have a couple of questions for you more informed/experienced lot

Is it most likely to be the front pads or could it be either/both?
Is there a protocol with 4x4's where you should replace all 4 sets of pads or are you OK just replacing fronts for example?
Is it an easy DIY job (as easy as replacing pads on any other car)?
Does anyone recommend a particular brand - mintex etc.?
Cheers for any help/advice.
