According to XF sales brochure from 2018, 350mm front discs were only standard (option code G36B) on S models (3.0d V6 and i4 300bhp) on UK market and optional equipment on other models with mandatory 18”+ wheels).
US market had on offer V6 380bhp which also had as standard 350mm front discs.
So unless when ordered that 350mm option was ticked, and it’s not S, yours are 325mm discs.

 

Thanks for the clarification. Just checked the build sheet. Nothing about any disc brake upgrades, so it must by 325mm.

 

My front discs are deffo 325mm, same as rear ones. Portfolio with 18” factory fitted wheels.

 

Mine could be same. My wheels look exactly like yours from pictures in your signature.

 

Just got a brake fluid change at halfords this morning. They did a free brake check and told me I need new front brakes and pads, quoting that I have 29mm left on the front discs. The discs don't look worn and don't have a lip at the outer edge. Also I have brand new pads on the rear which must be 16mm. They measured them as 9mm.

Should I just ignore this for now and look at it when I have to change the front pads or get a second opinion? Don't feel the report of Genuine.

 

New front discs are 30mm thick with minimum 28mm, so I doubt Halfords report to be genuine too. At 29mm it should be 50% and not 0%. And if wanting to be picky, how did they measure it to be exactly 29mm, with measuring tape?

 

One front. One rear.

 

Went to pickup parts at eurocarparts today and they told me I only need only one sensor, not two. Is this right?

 

Just to say that I had new front discs and pads fitted by the main agent where I bought the car, shortly after I bought it from them in 2019.This was due to judder on braking, (disc runout). These pads are still on the car, and I have to say that dust is minimal, so the wheels stay clean a lot longer. So if changing pads, try to get Jaguar OEM if you can. Some cheap pads create loads of dust and one is always having to clean it off.

 

I’m very pleased with EBC Redstuff I’ve put on rear axle last year. Very low dust and fantastic braking performance.

Now after nearly a year and 12k miles they still look like new

I got the EBC Redstuff rear brake pads fitted today. The garage warned me that they will squeak before fitting them and I told them to go ahead. All fitted now and they don't squeak at all .

 

Good point about the insurance investigators. They love a get out clause.
I thought the XE and X260 factory brakes were TRW? 325mm rear rather than 326 ATE.
Although I’m sure ATE make an aftermarket option.

I 'm not sure about this. It appears that many Jaguar boxed pads at least have the TRW logo painted on the thin backing plate but the pad underneath has the ATE/Galfer markings. I wonder if the hadrware was originally ATE but TRW also supply some discs and pads and rebadges ATE stuff where they don't have an alternative. I wonder if it is more supplies than engineering here. I don't know the XE and XF X260 parts so well but whenever I try and find what the originals are, there tell a mixed story

Modern ventilated disc are mechanically very stable and could very probably be worn down below 2mm and still operate adequately under typical conditions. But they are sized to still be thermally stable at the min. dimensions - stand up to heavy use even though a lot of material has been removed. Under these conditions, they could overheat and then brake performance would take a dive. Manufacturers are going to specify slightly on the safe side but crash/insurance investigators also work from the same starting points.

 

Have a look at the Bosch online catalogue rather than trusting what ECP say.
Car parts 4 less is the same company as ECP too. Often cheaper.

Don’t forget that 2mm wear on disc thickness is only 1mm a side. So if the lip you have on the disc is 1mm, then they might not go another 25k miles.
Having said that, I think they are very conservative with the minimum thickness.

 

I gave a call to eurocarparts to confirm the part and they said the bosch they have on their website which comes up for my reg won't fit my car. They suggested the following which look entirely different without the clips on top. A bit confused now.

BOSCH 0 986 494 819

Nice high-friction pads

 

A very rudimentary check suggests that the rear discs are 20 mm thick when new and can be worn down the usual 2 mm to 18 mm.

The 350 mm front discs are 32 mm thick.
The 325 front discs are 30 mm thick.

Again both have the usual 2 mm wear limit at which point the heat capacity of the remaining material drops below the set limit.

One slightly deeper groove, probably caused by a piece of grit wedged in the pad is of no concern.

Thanks for the response. Guess the discs haven't worn much given I have about 20mm still on the rear and 31mm on the front. Will just replace the pads now. Going for Bosch pads and Pagid sensors.

 

I took a second look. Did you get the same part numbers?

Front 350 mm discs:
T2H16147 or T2H53848 or T4N14764

Front 325mm discs:
T4N13434 or T2H53847

Rear:
Both sizes use the same pads
T2H52754 or T2H53866 or T2H9989 or T2H53849

Generic sensors should be fine. They are made by/for brake manufacturers and J aguar don't make their own either

I was only looking for the rear. Yes the part number I ended up with is T2H9989 or T2H53849 for the pads and T2H2091 for the wear sensor.
Also I see one of my disc has a visible groove. I measured the thickness of the disc and it is about 2cm. Do I need to consider replacing or resurfacing the discs?
Fronts seem to be ok. Pads have some thickness left and the disc is about 3.1cm.

 

There seem to be two front disc sizes and maybe two rear ones. It would be wise to check the sizes on your car and then check the parts list again. I'm not so familiar with the X260. The rear list looks hard to follow

 

Thanks for your help. I think I narrowed down the part now. I will get either Bosch or Brembo.
Will be going for a generic sensor.

 

I think the brakes on your car may be TRW, so you’d imagine that the TRW aftermarket stuff is the same as the factory originals. Check the DOT codes as Neilr suggests.

 

You should be able to get the part numbers for your model here: Search Genuine Brake Disc And Calipers Parts For Jaguar All New Xf 2016 > | Jaguar Land Rover Classic Parts

Jaguar usually use clip on wear sensors so the pad descriptions are basically meaningless. You always have to buy one sensor cable per axle but these are available pretty cheaply these days.

Most branded pads will be fine. If you are picky, there are some that are probably a little better but you have to start comparing the originals with the replacement's DOT friction grades and make an educated guess. Jaguar don't seem to buy cheap brake gear so downgrading is a fairly probably risk if you are not a little careful. I would not buy pads that don't display the DOT code and I my minimum grade is FF on any car.

Thanks for the information. I am stuggling to find the part number from the above link. My VIN ends in HCY46300. If I get the part number for below range, it should work for my car right?
FROM VIN HCY42650 - TO VIN LCY87623

Also do I need to replace both wear indicators every time with the pads or is this only if there's a problem with the indicator?

ECP suggests the below brakes with my Reg, but there's no information on the website.
