ceramic brake pad options for '13+ XFR?/brake wear sensor question
 

My brake warning indicator showed up yesterday on my '13 XFR at a little over 13K miles. I'm guessing (based on reading the forum) that it's my rear pads (and probably the rear rotors?). Rather than replace just the rears, I was going to replace front/rear pads and rotors in one fell swoop.

I've settled on the R1 rotors, but they only have semi-metallic pads (Posiquiets made by Centric) for the '13+ XFR. I can't seem to find any ceramic pads that fit. Everything I see online is either rear only (EBC Reds), or for the '12 or earlier XFR, or from a complete no-name brand that I've never heard of.

Does anybody have a suggestion for ceramic pads that definitely fit on the '13+ XFR?

Separately, does anyone know if the brakepad wear sensors are identical between '13+ XFRs and '12/earlier XFRs?

Thanks!

Several sellers on eBay who sell EBC Redstuffs for the '13 XFR front brakes, here's one:
EBC Redstuff Ceramic Low Dust Brake Pads DP32076C Front 1 Axel Set | eBay
You need part # DP32076C.

I have used EBC for both front and rear on stock rotors at 40,000 kms (25,000 mls approx). The rotors were good enough for a further full set of pads (measured by my mechanic).

I am reasonably sure that our rotors (discs) are the same on the rear (2011 XF S) at 326 mm (12.8 inch) diameter. However, I believe your front rotors (discs) are 380 mm (15 inch) diameter compared to my 355 mm (14 inch). So, as you say, there may not be an option from EBC.

I have also replaced both front and rear brake pad sensors (rear sensor is on the right wheel, front is on the left wheel) as they are wear-though type sensors and cannot be reused once triggered.

I imported all of my EBC pads and OEM sensor direct from Rimmer Bros in UK. If you quote your VIN number, they will ensure you get the right parts.

Good luck,
Mark.

I checked out the ebay stuff and the picture of the coating does not look quite right. Compare to the EBC web site.

I thought the XFR brakes were the same for all years.

That's what I was hoping, but if someone can confirm that would be great.

Also, my brake low warning indicator disappeared on its own. Is it possible it was a temporary false warning? 13K miles does seem to be pretty damn short for brakes to be worn out.

I have R1 rotors and I got s set of PostQuiet ceramic pads at the same time. My 2010 XF SC has the larger 380mm brakes (same as the 2010 XFR). Would suggest calling PostQuiet to see what fits your specific year

Do you want ceramics to have low dust? If so, EBC's still make a lot of dust, so don't go that route.

I use Akebono and some obscure brands when Akebono aren't available. Akebono are near zero dust.

Akebono don't make brake pads for the XFR, well at least not the fronts.

EBC Red are low dust not no dust pads. I switched from stock to EBC and there is significantly less dust. And it's lighter color than stock and the pads are more progressive with less grabby initial bite. I like them, but haven't tried anything else.

So what brand of pad do you use on the rear of your 2 XFs?

I went with Centric Ceramic pads and, as others noted above with ceramics, the initial bite is reduced but there is about 95% reduction in dust. When there is dust it isn't black so you can barely tell there is any dust on the wheels. I think it is a pretty good trade off. The OEM pads were a bit too touchy anyway.

I checked CarID web site last night and they show a range of packages and brands available for the XFR 2013. Here is the link:

2013 Jaguar XFR Performance Brakes | Pads, Rotors, Calipers

Ended up going with R1 slotted/crossdrilled rotors and Centric Posiquiet semi-metallic pads as my brake warning light started staying on consistently.

The shop that did the pad/rotor replacement for me noted 35.6mm thickness for the front rotors, and 25.6mm thickness on the rear rotors. Does anybody know what new vs minimum thickness is on the XFR rotors? We looked all over the old OEM rotors and couldn't find any numbers stamped on them.

Pad thickness was between 14.1mm-15.7mm on the fronts, and 11.4-12.2mm on the rears. I was under the impression that 4mm was kind of the "red zone" for minimum pad thickness, so it appears despite the brake low sensor going off, i still had a lot of miles to go before i was really in trouble. Live and learn i guess for the next set of pads.

Separately, I'm planning on flushing the OEM fluid and replacing with ATE SL.6 fluid (ISO 4925 Class 6 certified). Any reason why that would be an issue vs OEM fluid?

Front rotors - new 36 mm, minimum 34 mm.
Rear rotors - new 26 mm, minimum 24 mm.

Looks like all your brake components were basically new! Hope you kept them in case you ever wanted to go back. You could definitely reuse if you kept track of which discs went with which pads.

I do not understand the desire to change the fluid. There is the problem of completely flushing and what benefit do you expect?

The shop added a small amount of non-OEM fluid to the reservoir while bleeding the brakes, so I'd rather have a full flush of all the same fluid rather than a slightly mixed fluid.

Also, I'm approaching 2 years with my car. The Jaguar recommended fluid change is 3 years, so not far off. Getting it flushed now will make next year's service slightly cheaper.

What makes the brake fluid Jaguar uses to be changed every two years? Or is it more of a cover their butts revenue generation thing?

Brake fluid can become contaminated with water and corrode the working parts. I think the fluid change covers them on that. I don't think the fluid change is expected to be anything like as thorough as you would need to be changing fluid type.

I would not consider changing to a different fluid unless their was a good reason to do so since materials (seals, tubes, metals) used in a brake system are designed and tested with a specific fluid. Changing introduces an unknown.
On the other hand, if you race your car and brake so hard that the specified fluid nears the boiling point, I suspect you are changing your brakes so frequently that corrosion and seal breakdown are NOT a concern!
