+1 Btw my brakes squeal sometimes and I don't have the CCBS.

 

here's the article: https://www.dropbox.com/sh/xl7ww123t...OXjzQEvpa?dl=0

 

Except when the brakes have been used heavily and the nanny inside the F starts squawking a "overheated brakes" warning and limps the car. Happened to me at the Jaguar academy

 

That's fantastic - thanks so much for taking the time to load it all up!

 

I assume that the carbon ceramic brakes on the F-Type are the same ones that were fitted to the XKR-S GT ?

You would hope that they don't ever wear out...

I don't see the CCB parts listed for the F-Type, but the prices for the XKR-S GT rotors & pads are phenomenal...

Front rotors, T2R13428, $4666 plus tax (this is a "kit" so I assume it's a pair)
Front pad kit, T2R11420, $1800 plus tax
Rear rotors, T2R10306, $4400 plus tax (this is a "kit" so I assume it's a pair)
Rear pad kit, T2R11424, $1800 plus tax

Those are USD prices based on the GBP pricing...

If you ever need to do that pads & rotors on your car, probably a $15K job...

 

In the article that shift just posted, Brembo's Giuseppe Micheletti is quoted as saying, "The hardness of the [disc] surface is so high that in road usage it is difficult to generate mechanical wear and disc life is probably longer than vehicle life".

Let's hope that's not just sales speak (he is, after all, somewhat biased). It is not the replacement cost that bothers me on this point - it is the expectations established at time of sale for the total cost of ownership during the period you have the vehicle. My expectations with these CCB's on the R is they should last a LONG time (unless I somehow abuse them).

As I've touched on in previous posts, I have previously needed to purchase 6 Audi steel rotors (4 for the Q7 and 2 on the front for the RS5), with the dealer pressing me to purchase four more for the RS5 at the very next service. This last one was a blatant dealer rip-off attempt, since they told me my fronts needed replacing only 4 months after the prior replacement (with no tracking in between). At AUD$3.5K per pair for the genuine RS5 steel rotors, I was furious.

But the point is, if the dealer openly sets the expectation for you at the time of purchase that you should be contemplating at least one set of rotors every 25,000 km's (for example), then you go into the car purchase with open eyes and wallet ready.

On the other hand, getting a $7k rude surprise 2 years into owning the car is a major negative if you're not expecting it, and makes you feel like you were somewhat exploited by the original salesman.

Rant over...

 

Hey, F-Typical - just read Shift's post of the article. Your cited statistics (red above) were wrong.

The steels only averaged better over the "selected 10 best stops", not the whole 20.

As quoted, "the ceramic cars test average was 2.9m shorter than that of the cast iron car".

Also, the cast irons were going in to total failure at the 20th stop, which is why they stopped the test there, I suspect.

Also, I noted they said the ceramics came up to operating temperature in 3 stops, whereas the cast irons took 4 stops to reach operating temp. What they didnt mention anywhere was what was the ambient temperature of the air - I wonder when and where (somewhere in UK, I guess) the test was run and what effect your cold northern climates I keep reading about will have on either set up.

Much to consider (both ways).

I also had to laugh that the opening paragraph says, "evo gives the definitive verdict", but their second last sentence in the article says, "we'll leave you to reach your own verdict as to whether or not that warrants, in the case of the Jaguar, the £7400 outlay"!

 

I will exercise great caution and do everything in my power to avoid making even one "panic stop" from 100 mph.

 

regarding cost, that's what I've read also. CC are not bad if you amortize over lifetime, BUT, if something goes wrong, then the cost to replace is insane.

 

I actually love doing this to test out the brakes and experience deceleration. Maybe not from 100mph but from 60-80mph, either on empty backroads or exiting freeways. Trying to test acceleration on public roads is risky. But exiting a freeway, I love to aggressive brake if no one is behind me. power + braking + handling = sports car, gotta play around with every aspect.

 

Oh sure, me too, but as I said, not panic stops from 100 mph on a public road in the US. That's a "careless and reckless driving" charge in the majority of jurisdictions, that carries with it major consequences, which aren't worth it.

I do what you describe as well because is it fun, but we're not talking about panic stops as described in the Evo mag. test. If you have reason to do repeated hard braking from high speeds during a short period on a public street or highway, there's something seriously wrong with you.

 

How do they define the lifetime of the vehicle ?


Is it in time, or mileage ?


Are CCB s affected by age ? or have they not been around long enough for anybody to suffer from any degradation from UV rays/ pollution or such ?


Because with some of the prices I have seen for replacement, in 10 years or so, you will not be able to give any car away if the carbon brakes have any sort of wear/ problem.

 

I've never found that limit. The lifetime of my new F-Type will certainly be longer than my remaining lifetime. (unless I accidentally kill it or vice versa)

 

Fair points. Just reread it more carefully and the 20 stop averages are 91.3m for the CCBs, but 94.2m for the iron brakes.

The 90.4m vs. 89.8m figures appear in the following paragraph where it does state that this was for the 10 best runs for each car.

 

I was curious why ceramic brakes were not being offered with the six speed. The V6S auto. can be had with ceramics, but not the V6S manual. I contacted Jaguar and their response was as follows: "Because of engine braking the MT car can slow much more quickly than AT equipped car and therefore does not need ceramic brakes."


Have you ever heard such a crock of s***?

 

Now that's a dumb response! (From Jag, I mean, not you!)

 

Yes, dumb indeed. I guess they forgot the auto could also be driven exactly like a conventional manual.

 

Not a taxi...

 

Hmm... Fast taxi! Heh-heh!

 

I test drove the R coupe without the ceramics and I felt the brakes were more then adequate for street use. I knew I would have an occasional track days I went with the ceramics. I don't know how the standard brakes would hold up to track duty (this is a relatively heavy car) but I can say that after two track days with the CCB I am glad I went with them. Fade free lap after lap.
