Brake Upgrade to recommend
#1
![Default](/forum/images/icons/icon1.gif)
Hi,
My current ride is a 2009 Jaguar XF 3.0 petrol NA premium luxury edition using Continental Sport Contact 5 tyres 245/45/R18. I am looking to upgrade my brakes and I would appreciate any recommendations.
I was thinking of just changing my front brakes to AP Racing CP 9040 brake kit or just changing the stock brake pads to EBC yellow stuff. To put things in context, I stay in tropical Singapore where the temperature is usually above 30 degree celsius and very humid. there are heavy rain pour and thunderstorms from time to time and it's pretty much city driving all way round here.
Do I need to change both the front and rear brake pads? what specifications should I look out for which would suit the car without having to do much modifications (eg: size/diameter/thickness)? Can I change the brakes myself or would that be way too complicated? Is it possible to put on the brakes from an XFR to my vehicle or from an XJ?
Regards,
Nick

Well, there's two reasons - one, for aesthetics. Not just the look of a BBK but also the stock kit leaves a lot of brake dust on the rims. Especially in rainy Singapore.
Two, I just got involved in an accident and rear ended a motorcyclist. I'm a little less confident of the brakes I now have. From the on board video, I had two seconds to react to the motorcyclist suddenly stopping and while I reacted immediately, I couldn't stop my vehicle in in time. While I know that it could all be psychological and changing changing the brakes may not improve stopping time at all, at least would have the psychological confidence to even drive the car.
Thanks in advance for any help I can get.

Faraway, take a look at: Front Rear Kit Powersport Drilled Slotted Brake Rotors Ceramic Pads BZ00921 | eBay.
This is probably what you would be interested in. I can't speak for how they will work on an XF, but I installed a similar kit on my X-Type and the braking is better, the dust is next to nothing, and the pads/rotors are lasting for what seems like forever (I'm at 60K miles on the setup and maybe half way through the pads and the rotors are showing very minimal wear). THe only "downside" that I can say is that first thing in the morning, the brakes will give a little "whir" sound. But, after a braking or two, the noise is pretty much gone. You may also notice a little bit of whir during extremely hard braking. But, during something like that, I doubt you will be worrying about the noise.
On a side note, one of these days I am going to make it back to Singapore. I loved it when I was visiting your country back in 2004. I didn't have enough time to see all that I wanted to. One of these days I will be back.

Got EBC Yellowstuff installed on my 2008 XF 4.2L a couple of weeks ago (rear & front with stock break discs). Great breaking performance, especially while heated (my driving style is sometimes aggressive, mostly within the city). Still getting some squeak while breaking, but hope this will be gone after pads will adjust itself to the discs.

Welcome to AP Racing
Hi, I am from Singapore and am currently driving a year 2009 Jaguar XF 3.0L petrol premium luxury edition. The curb weight of the car is about 1700kgs. I do not race my car nor do I go on tracks. In fact everything on the car is currently stock edition. The drive is mainly city driving with a lot of stop and go and I do not go beyond travelling at 130 km per hour. I am now interested in changing the front brakes of my vehicle but have been left confused by the salesmen here. As such, I am writing to you for clarification.
I have been recommended the CP7040 and the CP5060. I was told that the CP 5060 is a better brake caliper because it is used for racing and as such if it can stand up to racing requirements, handling the roads on a daily basis is no problem. But I have been told that calipers designed for racing are not meant for road use. Please advice me on the best brakes to get for my car and for my usage. I am looking for a brake set that would give me improved braking power and with it confidence to know that I can bring the car to a complete stop in an emergency braking system. I am told that my salesmen would manufacture the brackets and bells for installation.
Regards, Nicholas

Dear Sir
Firstly I need to point out that AP Racing UK factory do not list a brake kit for this Jaguar Model. Therefore the brakes are being offered to you are being developed by a 3rd party using AP Racing calipers and possibly discs? So we have no input into this procedure.
If it is a road car then stay with road car brakes and don’t entertain the CP5060.
For the Gross vehicle weight of below 2,200Kg you should use CP9040 caliper with a disc upto Ø363x32mm, but can use 355x32mm if the wheel restricts it?
CP9040 is the latest version of CP7040 and directly replaces it.

CP7040 is only rated to GVW or 1,900Kg
Suitable discs

Our cars already come with 4 piston calipers on the front. You probably won't get any better performance unless you get a 6 or 8 piston caliper, but of course going with something like that will mean you will also have to get bigger rotors and bigger wheels. But the truth in stopping your car does not lie in the brakes but in your tires. Brakes only provide the friction needed to slow your tires down. if you want to stop faster, get stickier tires. The only thing bigger brakes will do is give you a bigger friction surface, which means it takes longer to heat it up and fail. which is only good for racing where you'll be using your brakes a lot. for normal street driving, the only thing they do is look cool but they actually might cause your braking to be worse. Racing brakes operate at temperatures suitable for racing conditions, normal driving rarely meets those conditions, and therefore your brakes might not be hot enough to provide the friction needed to stop your car in an emergency situation.
