No . This is not correct.

 

Thanks. My search for rear pads and rotors has been frustrating at best. Calls to parts suppliers have yielded different answers. Web searches have also come up with conflicting information, with some indicating it depends on the engine size, 2.0, 3.0, or 5.0, and others claiming the wheel size is the deciding factor in which size rotors are installed. Looking to go with EBC slotted/dimpled rotors with Yellowstuff pads. Replaced OEM with those on a previous Evoque and loved the results.

 

Yeah, I’m gathering parts for a rear brake job on my 2020 110X P400. And I’ve been so confused it’s unreal. Even the catalogue on the Land Rover website at https://parts.jaguarlandroverclassic...nd/land-rover/ is incorrect, so there is darn good reason that there is confusion in the marketplace here. It just says, 18, 19, 20/22. That is incorrect based on what was delivered on my vehicle. PS --and resellers get it confused too (Atlantic British’s / Rovers North’s website is wrong too, for example.)

You would think the X, with red painted brake calipers and 20” wheels would have the biggest rear brakes -- it does not. I have the 350mm rear brakes. It’s funny because Gavin has mentioned this to me looking at my brakes trail side.

350mm rear rotor - all parts supersede now to LR187242
365mm rear rotor -- all parts supercede now to LR161899

BTW I think I have figured an easy visual way to tell this between the 350/365 rear rotors. The “tell” is that the 350mm rotors are fluted around the hub, and the 365mm rotors are painted dark grey, no flutes. Where it starts to get really confusing is that some aftermarket 350mm rotors don’t have the fluted design, so ... there’s that. I’m talking original Genuine JLR rotors only here.

So this is incorrect from Rovers North Rovers’ Magazine that just showed up. These say 19” wheels but these are correct for mine with 20” factory wheels. I mean, could it be any more confusing?



350mm rotors with the fluted area around the hubs painted with a light grey anti-corrosion paint. Mine are like this on a 2020 P400 110 X w/ 20” wheels -- I have confirmed that I have 350mm rear rotors and they match these in look exactly. I measured them this weekend when I pulled my wheel off to change my bloody failed rear shock absorber.




365mm rear rotors look like this -- no fluting, grey anti-corrosion paint around the hub area - V8’s, or 22” rims on P400 only

 

Yikes, I’m with you on the confusion level, and based on your reply it’s increasing. I too have the fluted ribs on my rotors, so I would imagine they are the 350mm rotors, but I pulled the wheels and measured the radius from the outer edge to the center of the spindle and doubled it. I come up with 14.25 inches, which equates to 362mm. So, they are clearly not 350mm, but just shy of 365mm. 365mm is 14.37 inches, which is .12 inches larger than my rotor. .12 inches is 3mm, so do I assume that using a tape measure on a mounted rotor, being not the most scientifically accurate way to measure would account for that 3mm discrepancy? But if mine are 365mm, then why do they have the ribs that would indicate 350mm? A previous poster stated that the rotor size is dependent on the wheel size, so mine being 20” wheels would appear on paper to be the 380 front/365 rear setup, which doesn’t add up since they have the ribs, meaning 350mm. Scratching my head over this. Keep me posted on any more info you gather in your parts search. Thanks.

 

After several calls to brake parts suppliers and getting conflicting information, I paid a visit to my dealers part department. Inputting my VIN, he pulled a rotor off the shelf which was indicated for my ‘22 Defender 110 X Dynamic SE, with 20 inch wheels. Having brought a tape measure and physically measuring the rotor, the correct rotor for my application is 350mm. So, it appears that the wheel size is not a determining factor when replacing. Additional confusion is added when I called Summit Racing and they run my info and come up with 365mm rotors. Never had such a hard time ordering a set of pads and rotors. My speculation is that the three sizes, 380/365mm, 363/350mm, and 349/325mm may be related to the three engine choices, 5.0, 3.0, and 2.0L. I will update once I finally get the correct size rotors delivered.

 

Per the published spec sheet:

Bear in mind P300s w/ the 19" wheels get the same brakes as the 18" wheels - that's what I have on my P300 that came with 19" wheels.

 

It's really not that complicated.

If you really want to, you can look at the different three types of brakes and how to service hem in the shop manual. The little differences will become readily apparent. Failing that, look under the hood and have a look to see what type of engine you have.

 

The complication comes in when calls to two different parts suppliers, visits to numerous manufacturers and suppliers websites still returns different results. The specs chart provided above would indicate 380/365mm rotors on my P400 - petrol since I have 20” wheels. But nashvegas says a good indicator is that the 350mm have the flutes or ribs on them. My original rotors have the ribs, so I’m assuming mine are 350mm. Not fully convinced which are on mine. I guess I’ll have to pull them off, although I would have preferred to do it all at once.

 

Don’t listen to what salesbros are telling you.
Most don’t know what they’re talking about. Your brake type is tied to your ViN.

It really is as simple as outlined.

I am 100% positive you’re on the middle sized rotors if you have a P400 and it didn’t come on 22” rims

Why?

because they all come that way. No exceptions..


By all means make it more complex if you must.

pop a wheel off and measure them. Then you’ll have zero doubt. Couldn’t be easier. 5 minutes you’ll have your data confirming same.

Or just use your VIN

 

That’s what I’m going with, the VIN I provided to the parts counter at the dealership. But after nearly 50 years of wrenching, I’ve never come across such a difficult process of purchasing replacement parts. And who likes shipping wrong parts back? Once the parts are in my hands, I just want to get the job done.
