I'm have a hard time finding rear brake rotors for my 08 s-type. (except for Jag dealer who wants $438 for the pair. The issue is my car came with the smaller diameter 305mm discs. I find some listed on ebay and other sites but they all say they are for the front. Please let me know if anyone knows if the front and rear are the same style and size rotors.

 

The rear brake discs are 288mm in diameter and 20mm thick on a 2008 S-Type normally aspirated car.

 

Take a look here https://www.jaguarforums.com/forum/s...-143196/page2/

 

300 or 326 I think.

From EPC

 

Yes, I can see that in JPEC. So there appears to be a discrepancy. Very interesting.

Here is the page from the Workshop Manual from 2011-05-11...

 

It seems they changed the spec very late and now the 300mm discs are like hens teeth and shockingly expensive.

 

Thank you for posting the page from JPEC. I suppose anyone with a later car will need to measure the diameter of their rear brake discs to ensure the correct discs and pads can be located.

 

By now the cars may not have the OE ones i.e. may have had them replaced some time ago. Quite possibly by either size, as anyone changing the discs could have stumbled across either size as being what to buy.

(Different car, but there were two sizes stated by Jaguar for the rears of my STR. I went with the larger size, which was in JTIS.)

 

So:

VIN TO N52047 XR827087 288 mm
VIN N52048 -> C2C25338 300 mm

Thanks for all the great info. I am the second owner and know the first so the brakes have never been serviced. I finally found a dealer that would give me the part numbers for my car (based on the VIN) and found that mine are the "rate" 300 mm rear and, 305 mm front. They are $467 from my local dealer with 3-5 days delivery. I actually found one pair of rear discs, new, from a guy in California. Still expensive at $320 including shipping, but there are no more to be found. Fortunately, the front discs are available for a lot less. Thanks for you help

 

Would the original Jaguar rears from the ebay link above not do? Even with shipping it is cheap

Are you sure about the front ones? Typically the last S-Types had the 326mm discs.

What are the part numbers you were quoted. It may help someone else in the future.

 

Might be worth a shot
My 2002 S Type 4.0L V8 has 300mm front discs on it.
And 288mm on the rear.

Found a link to a UK seller that might be of help for you:

Jaguar S-Type Discs Parts - JustJagsUK.com

 

I have the ebay rotors on the way to me, should have them tomorrow.
I gave my vin number to a dealer and they gave me these part numbers:
Front rotors: C2C25335 - 305 mm
Rear rotors: C2C25338 300 mm
I haven't started on the front brakes as of today. Be assured I will measure the rotors before I purchase the new rotors.

 

I now notice that the 305mm front disc/rotors were not for the German market. I guess that is why they never appear on my parts comparators. I expect you are correct with your part numbers but a double check is always wise

Pattern part: https://www.ebay.com/itm/Jaguar-Pair...xZCH42&vxp=mtr

Original: https://www.ebay.com/itm/Jaguar-C2C2...VZNRzr&vxp=mtr

 

That is correct for all the X200 models. Some models came with bigger front discs from X202 onwards (320, 326 and also these 305 mm ones).

Most rears were 288 mm but it seems that some also had these 300 mm ones

 

So, anyone know where an 07' 4.2 fits in this millieu for rear rotors? Fleabay calls for 326mm.

 

Call your nearest Jaguar dealership parts department with your VIN and ask them to tell you what specific rotors you need. Get their part number, then you can begin your online search for a much better-priced equivalent....

 

I got pads and rotors for the rear on my car at the local NAPA store a couple of years ago and they were reasonably priced and good quality, don't get the cheapest ones though. My car is a 2003 with a 4.2 motor, but they should have them for yours too. Be sure to bring your old ones to see make sure that they match. The rotors were about the same price as having the old ones turned.
