My DS is going in to fix the Brake Pad Wear warning light, came in at 15500 miles, suspect it's the rears as fronts clearly OK. Yours is even lower mileage, I wonder if there's some stability control independent braking going on.

 

I've done 33k on my rears, (replaced with discs under warranty) and 52k on factory originals. I've still got 6mm on the fronts too. I guess it's how you drive it that counts

 

I have the brake judder (2020 DS with only 7000 miles). Dealer have checked it and said the rear discs and pads needs replaced. We are currently checking if this will be covered by the warranty - which it better be because that is shocking.

From my time working in brake engineering, the front and rear, inboard and outboard pad materials were designed to expire at roughly the same time. Whilst this was a few years ago, now I can't imagine manufacturers would add (or pay for) more brake material than required.

While you can probably wear the fronts out before the rears (rear brakes hardly do anything on an unladen car), to make the rears wear more you'd have to be driving it around laden to the gunwhales all the time (or with prodigious use of the handbrake in the good old manual handbrake days&#8230.

I wonder if on softly suspended, high riding 4x4s the rear brakes come on fractionally before the rears to prevent dive. A bit risky in low grip conditions though, perhaps the electric stability systems are used to mop up any problems.

 

A further thought is i was wondering if the calipers are designed to slide, but mine aren't because i have the uneven pad wear. Its as if most of the braking is done on the outers.

Dunno, but my old Freelander 2 always used to need rears doing before fronts. Don't know if it's the same set-up, but the C-It-Now video they emailed me when it was in for an oil change the other week stated 3mm rears, and 6mm fronts remaining. All four discs corroded and lipped. Rears have only done 33k, fronts still Factory fitted from 2016!

Fist type calipers, usually single piston, or calipers with a hydraulic connection to just one side of the disc are designed to slide and yes, uneven outer and inner pad wear would indicate it's not sliding properly to even up the wear.
