Hi, I have a 2015 Jaguar XF 3.0 Supercharged AWD.

The steering wheel is juddery/shakey while braking that leads me to believe that the brake rotors have warped, and I want to change the brakes as they were last done in 2017 through the dealership.

My XF has 355 mm Rotors up front and 326 mm rotors in the rear. (Correct me If I'm wrong)

I got a quote fromt he dealership for the OE parts:
Contains: Front rotors, pads and sensor wire.
Rear rotor, pads and sensor wire.

Quote from JLR Dealership

I searched online for aftermarket rotors and pads and came accross multiple examples, some of which appear to be higher quality.

StopTech Brake Rotors - Sport Drilled & Slotted Sport Rotor

127.20024L (FRONT LEFT) $152.96
127.20024L - StopTech Brake Rotors - Sport Drilled & Slotted - North American Parts - Automotive Parts Supply

127.20024R (FRONT RIGHT) $152.96
127.20024R - StopTech Brake Rotors - Sport Drilled & Slotted - North American Parts - Automotive Parts Supply

127.20022CL (REAR LEFT) $141.53
127.20022CL - StopTech Brake Rotors - Cryo Drilled & Slotted - North American Parts - Automotive Parts Supply

127.20022CR (REAR RIGHT) $141.53
127.20022CR - StopTech Brake Rotors - Cryo Drilled & Slotted - North American Parts - Automotive Parts Supply

Total: 588.98 USD ~$800 CAD
With StopTech Brake pads: $811.23 USD ~ $1,100 (No tax, no shipping cost)

Here is a Youtube video that shows installation and use of StopTech Rotors and pads with OE Brake sensor wire.



I'd like opinions regarding OE vs Aftermakret brake rotors and pads, the cost difference is significant and I plan to do the job myself (Never done it before but have the necessary tools)
Never heard of or used Stoptech products, has anyone else used them and were happy with them? Would you recommend a different brand/type of rotors and pad combo?

I have about 2 weeks to get all the necessary parts and performt he service, any opinions, suggestion and help is greatly appreciated.

Cheers!

 

Heaps of threads and posts on this forum about the same or similar questions about the brakes - "should I take it to the dealership to have OEM parts fitted or should I go after-market/ DIY?"
The answer is the same in all cases - the amount charged by the dealership is absolute highway robbery, after-market parts are just as good if not better (especially regards waaaaaay less dusty brake pads), and DIY is easy and saves you a bundle on the labour charge.
It really is a no-brainer, go with after-market rotors and pads and DIY and save yourself several hundred if not thousands of $.
I have DIY changed the rotors and pads several times across XFS, XFR and F-Type and literally saved thousands, with the added satisfaction of knowing it has been done right, and never had a single problem with the brakes afterwards.
The only proviso is if the car us still under warranty, if it is then best not to DIY but you can still use after-market parts and an independent brake shop to do the work and still save a bundle.

 

Aftermarket is great

I got these https://www.rockauto.com/en/moreinfo...504953&jsn=398 work great

 

$406 USD, that's half the price of a set I'm aiming for. Awesome!

Thanks Jssaab!

 

Noted, I found several threads discussing after market, was looking to get updated info, perhaps for parts that are new to the market, etc.

Could you share the brand and type (model number) pads and rotor you used in the F Type? Not sure if you have the upgraded 380 mm rotors or same as my XF 355 mm.

Thanks for the input, definitely going aftermarket, stopped caring about warranty when I paid out of pocket for 3 major repairs that warranty wouldn't cover.

 

I put Hart brand slotted and drilled rotors on the F-Type, originally bought for my XFR over four years ago then moved over to the F-Type.
But these are the 380 mm front and 376 mm rear, no good for your car.
I have Porterfield R4S pads but again I am not sure if they make them for your brakes.
The rotor and pad kit linked below by Jssaab looks good for your car and the Power Stop rotors look pretty much identical to the Hart ones I have (other than the sizing)..
I put Power Stop Evolution Z16 pads in the exact same sizes on my old XFS and they were brilliant, still the smoothest quietest and lowest dust pads I have ever used.
The Z16 are not as aggressive as the linked Z23 and they may be all you need for normal street use, and I bought them from Rock Auto for a very low price.
I don't think you will do better bang for your buck than the kit linked by Jssaab.

 

Thanks OZ, I'll aim for the Z23 linked by Jssaab.

 

Found these:

[FULL KIT] BLACK HART DRILLED SLOTTED BRAKE ROTORS AND CERAMIC PAD BHCC.20023.02 - $241.68 USD

and

Power Stop K6283 Front & Rear Z23 Evolution Sport Brake Upgrade Kit - $349.71 USD

Both seem sort of too good to be true deal. Which one would you rather pick? The black rotors look fancy looking, but more importantly cheaper, and if they're the same quality then I rather pick those. This entire set is cheaper than just front OE pads. LOL

 

The rotors are very likely identical other than for the black coating.
The coating wears off the braking surfaces very quickly (as it is meant to) but remains on the hats/hubs.
The pads with the Hart kit may or may not be true ceramic pads, the Hart kit I bought some four years ago for the XFR also advertised the pads as ceramic but they turned out to be the exact same Centric Posi Quiet semi-metallic pads I already had. Not bad pads but not as smooth and quiet and nowhere near as low dust as the Power Stop Z16 ceramic pads.
Conversely the Power Stop kit will be sure to include genuine ceramic pads.
Your choice - pay a bit less for the Hart kit and take a chance on the pads, or pay more for the Power Stop kit and be sure of getting ceramic pads.
And no, the price of neither kit is "too good to be true", it's just that the OEM rotors and pads are exorbitantly priced.

 

I had the same problem with my 2010 XF. Unless you had the routers tested and you have a true warp on them I would hold off on your purchase until you do this test that worked for me.

First let me say that I am light on the brake peddle when backing resulting on the rear brakes not adjusting properly. Before I put the car on the lift I drove the car to an area that I can backup a few times to adjust the rear brakes by braking a little harder than I normally do. I did that a few times and to my surprise the problem with the pulsing brakes went away. I would suggest doing this before you begin spend money on something that is not broken.

 

Either of these will work fine, if you want to go super cheap or just cheap.

I like the black anodize hubs, but the stop powerstop ones are coated and have not shown any rust at all yet on the hubs. I might still paint them with high temp paint when I paint my calipers

These Z23 pads are insane, tops like a sonofabitch, better than Jaguar for sure and no dust. Carbon fiber ceramic pads, who knew. Quiet too.

Great idea, always worth trying something non-invasive before going ll in on surgery ( I always tell patients that as well) although that';s a wayback thing, adjusting brakes in revers pumping them. Don;t know how that would work here but why not.

 

Weighing both options, and although the black coating/paint looks good, it's not as OE looking as the standard silver ones and $100 extra for nicer pads is well worth the price (be it at a gamble).

I also read that drilled rotors provide no benifit aside from aesthetics in exchange for the drilled areas being prone to cracking over time due to temp variation; where as, just slotted are overall beneficial with no real drawback aside from accelerated pad wear.


Sticking with power stop. Appreciate the input.

 

Ordering Powerstop kit like the one you suggested. Found a cheaper listing on Amazon, I don't imagine they're fake....I have had some bad experience shopping with amazon, but let me know what you think.

Thanks for the great recommendation Dr Jssaab!

 

Hey, maybe I'm misunderstanding this. The vibration is in the steering wheel, which would most likely be due to defect in front rotors as opposed to rear ones.

I had my alignment done few months ago when a tech (from a general tire shop) pointed out that my front rotors are warped, and that my brake lines were stretched.

Last I had the service done was from a Jaguar dealership, brake have never been changed prior to that. I haven't inspected the brake lines in great detail myself, but they appear fine. I should be looking at deformed rubber brake lines, broke/damaged holder clips etc.


I'll try the rest you prescribed.
Reverse 20-30 Kmh and attempt several hard brakes. (In an open area)

Thanks Gus!

 

My vibration was in the steering wheel as well..

Yes drilled slotted look way the EFF cool.. no other purpose really on a daily driver.

I think it said those were shipped and sold by amazon. The usually only buy direct from manufacturer I only buy form them even if I pay more unless Amazon does not sell the thing I want

 

Have you had any luck with my suggestion or did you make the repairs? What did you find?

I know that I am new to the XF but I am not new to Jaguar.

 

Hey Gus, no not yet. The car is currently at the dealership getting its supercharger replaced. Will be getting back next week.

I ordered powerstop brakes from the US for good measure. Will update you if I end up getting away with brake pad calibration remedy or replacing rotors and pads altogether.

Thanks for checking in!

 

Noted, so I ended up ordering the set from Amazon.
