Modern brakes are designed to wear out the rotors as well as the pads. Generally you replace the rotors every second pad change or even every pad change.

Harder pads will wear out the rotors faster. Rotors are cheap compared to the best pads.
Good point. Rotors used to last several pad changes but these newer harder pads fitted to high performance vehicles will easily wear out the rotors (used to be that only Astons and Ferraris and such needed rotor changes with every new set of pads). One of the penalties we get for driving 4000 + lbs cars with high performance engines I suppose.

Mind you Murrieta, who only got 9,000 miles out of his pads, seems to be a tad unfortunate and not what he should have expected. I have nearly 15K on my XF and the pads have plenty of wear left. I drive 60 miles a day through traffic and toll road traffic, so I get a good mix of stop start and 70 mph plus driving every day. I will have to keep an eye on pad wear rates on my car.

I notice that in road tests the XF has very good (i.e. short) stopping distances when compared to equivalent cars, so maybe this is the penalty for that performance. Also several people have complained that the XF can be difficult to bring to a smooth stop until you have practiced a little - I have no problem these days but when I first took delivery I was a little jerky (problems I had not had when testing Audi, BMW and MB).

Don't forget about the new wheel protectant products that have been availabe in Europe for some time and are now in the US.(Armorall Wheel Protectant).
These products don't completely solve the brake dust problem but they do offer a fix short of problematic ceramic pads and the resultant increased ware to the rotors. There is an issue reletive to reduced braking with cold components as well and thats where most of our cars live.

Rear brake wear may be related to defects in the EPB system. My theory is that the traction control/DSC can also wear the rear brakes faster than you might expect as the rear brakes operate to control yaw and traction issues.

Great point Jagular.......since I haven't been using the EPB my rear brake dust has been reduced substantially; I suspect it may have to do with the release mechanism not fully releasing initially.

Oh, man.... I love my car, but I can't believe I'm sitting here reading about brake dust.

I just picked up a can over the weekend and it made a dramatic improvement in the brake dust after 75 miles or since then. I'd normally clean my wheels every night (I know....) after about a 20 mile to/from commute. I've driven 75 miles since the application and I see no brake dust yet.

So now you don't have to chew up your brake rotors with ceramic pads that actually reduce braking capacity for normal driving and you save a pant load of money too.
Oh geez, the boy racers are going to eat me alive for that one. Well I don't care who you are that's funny and the truth too!

Didn't believe it at first but it actually works!!!



Been using it on the S-type 12 spoke wheels for the last few months and it works great.

Default Same here

I just bought a 2016 F. type and the brake dust problem is much worse than my last two Jag sedans, which were bad. It will probably get better with more miles but I will probably try the Armour All product

I wonder if Jag wanted more stopping power in the F and positive braking with the graphite type pads..My XF has vey little pad dust (very surprising)..Mercedes where all about this too and have terrible brake dust issues.

If it were me..I'd find a suitable replacement pad in the ceramic make..of course I'd do some homework on Pad and rotor combos.
