2013 XKR about 25,000 miles and brake light indicator is starting to come on off and on. Two things, with out removing the wheels, any idea to tell which set is getting worn? Also, I was reading somewhere that the after market less dusty pads are hard to come by for a Porfollio series. Any thoughts?

 

I am running Textar ceramic pads see this link: https://textar.com/ I had them installed by a local tire shop. I am very satisfied with them. Total cost $355 about 3000 miles ago. Rear wheels stay much cleaner than the fronts which are still running original equipment pads.

 

Ralph do you have the up-graded brakes on your car? I am having a hard time finding pads for my Porfolio that fit.

Thanks,

Thomas

 

I'm not sure what you mean by "upgraded brakes". The discs were good and no change was required. So, maybe the answer is no as just the pads were replaced.

 

My build sheet lists:

Red calipers plus brake up grade.

I had my calipers painted sometime ago if that is what you mean by an upgrade. I had ceramic pads put in when the oe pads needed replacement to cut down on the brake dust/dirt. They are not quite as grippy as the oe's but if you are aware of it at the get go, you get used to the difference quite quickly and adjust your use of the brake pedal accordingly.

 

The red caliper plus upgrade is just the color. I believe all of the 5.0 XKR cars have the same calipers/pads front and back. I do not know if the 5.0 XK cars have the same calipers/pads so maybe someone can chime in here and let us know. The Alcon package could be the only difference but I don't know if they were offered on the 5.0 XKR cars.

 

Yup, all 5.0 XKRs have the same Teves brakes - they're 'upgraded' from the XK version. Here's the full list of brake types:

4.2 XK (ATE*): 326x30mm front, single piston, floating calliper; 326x20mm rear, single 45mm piston, floating calliper
4.2 XKR (ATE): 355x32mm front, single piston, floating calliper; 326x20mm rear, single 45mm piston, floating calliper
4.2 XKR (Alcon): 400x36mm front, six pistons (38.1, 34.9 & 30.2mm), fixed calliper; 350x28mm rear, quad 32mm pistons, fixed calliper
5.0 XK (ATE): 355x32mm front, single 60mm piston, floating calliper; 326x20mm rear, single 45mm piston, floating calliper
5.0 XKR (ATE): 380x36mm front, dual 42mm pistons, floating calliper; 376x26mm rear, single 45mm piston, floating calliper
