Anyone had luck with ceramic brakes that stop good for the XKR?
So replacing my brakes once again since last chnage two years ago
I had trw ceramic front and evolution ceramics on the rear. Long sorry short brakes are bad and braking power is reduced significantly from stock, I do not like then at all
I have had Akebuno ceramics on my old e55 amg and they Are amazing , stop great and no dust , so I found and ordered rear akebuno eur1095 brakes but Akebuno do not make front brakes for our cars so my options are open as what to get for the front
Please share your experience

I have Akebono all around on my '08 XK. They are great. Are XKR brakes different?

Apparently not a lot of XKR have ceramic brakes that are actually good judging by the lack of response

I have ceramic pads on my rear wheels, but not on the front yet. the rear wheel pads are Textar TEXC2P24219. They were installed in 3/18 some 12k miles ago and in late April had 50% life left according to the installer. Front pads replaced last fall 6k miles ago with OEM pads and have 70% life left in late April.

Isn't that a wear sensor cable?
The Textar pads for the 5.0 XKRs are 2511401 or 2202101. Both seem to be the same pad (edge code FE), with the 2202101 having the extra clamp springs from the XKR-S. They don't claim to be ceramic, as far as I could find.
The original ATE pads have a slightly better FF rating.
Personally, I don't find the original combination of ATE discs and Jurid pads (front) and ATE pads (rear) all that dusty. However, the Jurid 310 compound (edge code GG) is excellent and measures much better on the brake tester than the TRW pads I tried. The Jaguar engineers seemed to have picked those pads for performance as they are not cheap nor do they come from ATE like the rest of the braking equipment.
Ceramic-type pads may be cleaner (Redstuff was a bit but their cold performance was poor and their hot performance just normal) but there still seems to be a trade off in friction levels which means more pedal pressure required for the same stop so effectively less easy to modulate the pressure you actually want. This is possibly not a big deal for digital drivers ...

Jurid White ceramic pads (part number 573150JC) will fit into the caliper housing but the friction material is too thick as supplied. I bought these, not realising this, I ended up grinding about 1.8mm off each pad to get them in. Initial impressions were poor but I may not have filed them totally flat. They've done a few hundred miles now and feel a lot better. They're far, far less dusty than stock pads.
Braking performance on the 5.0 XKR with stock pads is very good IMHO. Direct comparison is difficult as the new pads have taken a long time to bed in. Would I do it again? Probably not, it took a lot of work to grind the pads down. I'll just get the wheels powdercoated in black and install OE pads next time

I recently changed from OE pads to PowerStop Z23 Evolution Sport pads on my XK. They work fine when warm but I'm not happy with the lack initial bite when cold--the first stop of a drive can require a fair amount of pedal pressure to come to a complete stop. I have not yet tried them on track or autocross.

I just checked the invoice again and that is the number on the invoice. On the other hand according to the current Textar catalog the number is 2447401 for non-performance brakes and 2485001 for performance brakes (front). Rear 2511401 for non-performance and 2485101 for performance brakes.

The XKR-S GT had real carbon-ceramic brakes and are different again.
2485001 and 2485101 look like they fit the 4.2 cars with the Alcon brakes. They can't fit the standard calipers on a 5.0 car. One has to be very careful with aftermarket catalogs - they are often misleading

The Jaguar pads are about 19 mm thick. Many pad manufacturers say that the BMW fit (up to 20.6 mm thick) are also suitable for the Jaguars with the similar calipers, however, this does not seem to be the case.

I've tried all kinds of rotors and pads and even messed around a bit with different combinations... and I've come to the conclusion that I will stick to OEM. They work well enough, cold, hot or wet. They certainly last longer and that dreaded 'pulsation' signalling a warped rotor is severely reduced. So like Stuart, I lean over and give them a quick wipe weekly.

We all seem to have different sensitivity with our brake foot so unless there is a head to head test of pads and rotors the difference in braking performance is most likely negligible. For those who track their cars if it were me there would be no doubt I would go to a performance pad and switch them out after track day. As a typical cruiser whether I stop a foot shorter or less there isn't a need to shop various pads. As to dust so far I don't consider my OEM pads that bad but then again I wipe down the wheels after every other run. Will I go to ceramics when my OEM's wear out , it's a maybe and I'll have to wait and see. At my present 24K miles and based on my last brake check I've got more then 50% pad life left so maybe in another 5 years I'll have to deal with it. Enjoy the ride.
